<![CDATA[Head Swap Donor Matching Guide]]> https://www.donordrives.com/blog/matching-guide/ The following instructions are for maximizing compatibility when looking for a donor head stack assembly. Be aware that there is no way to 100% guarantee a match, but following these guidelines will help you increase the chances of locating a successful donor.

Locate the make of hard drive you are working on, and then try to match the specs listed. Please note that we do not cover Quantum or very old Western Digital drives (pre-Caviar) here. For any information visible on the label, we have highlighted where you can find that in the accompanying example label for each type. Your label may look different, depending on the date or the product line that the drive belongs to.

We have prioritized and color coded each aspect. Chances are, you won't be able to find a donor that matches all of these specs, but using the color-coding you can see which information is more important.

  • RED - Essential. You almost certainly cannot use a donor without this matching.
  • ORANGE - High priority. This information often is required to match for a donor to be compatible.
  • YELLOW - Medium priority. This information can help increase the chances of compatibility if a match is available.
  • GREEN - Low priority. This is normally not a factor, but can be used to choose between multiple donors matching everything else.

Western Digital

Caviar 1st Edition

These are generally drives that are 10 or more years old. They can be differentiated by having a PCB that is, more or less, square compared to the L-shaped PCBs of later models.

Use the following criteria to find a donor drive.

  • Model number: Match the entire first part of the model number as well as three characters in the second part. Eg: WD800BB-55JKA0
  • Heads map: Match the physical heads (PH) map exactly. It is OK if the donor has more heads than the original drive, but all heads before that should match.
  • DCM: Locate the J or 2 in the DCM. It should be towards the end. Make sure that the J or 2 as well as the preceding character matches on the donor.
  • Country of manufacture: Should be the same.
  • Date of manufacture: Should be within three months — the closer the better.
  • Serial number: Match the first four digits of the serial numbers.
  • PCB Revision: The PCB Rev should be the same.

Marvell (version 1)

These drives can be identified by the family code in the model number (the 3rd and 4th digits after the hyphen). The following families are part of this type: Mammoth (family codes EY, EZ, FA, FC, FJ, FM, HE, HF, JE, JS, JT, JY), Sabre (JH, JJ, JK, JL, JM, JN, JP, JR, JU, KS, LN, MG), Hawk (MH, MJ, MK, ML, MV, MW, MY, MZ, NC, ND, NE, NF, NG, NH, NJ, NK, NT, NV, NY, PA), Hawk-2 (SG, SH, TG), Starling (RD, RE, RF, RJ, RK, RL), Buccaneer (KE, KF, KG, KM), Zeus (MN, MP, VJ), and Raider (PC, PD, PE, PF, PG). Even if these families of drives say "Caviar SE" on the label, they belong to the Marvell architecture.

Use the following criteria to find a donor drive.

  • Model number: It is ideal to match the whole model number, but if none is available you can try one that matches the entire first part of the model number as well as these three characters in the second part: WD1600JB-40TGB0
  • Heads map: Match the physical heads (PH) map exactly. It is OK if the donor has more heads than the original drive, but all heads before that should match.
  • DCM: Locate the J or 2 in the DCM. It should be towards the end. Make sure that the J or 2 as well as the preceding character matches on the donor. If the three characters before that match as well, it will have an even better chance of being a match.
  • Date of manufacture: Should be within three months — the closer the better.
  • Preamplifier: Exact match for both vendor and revision.
  • Microjogs: Each value should be within 300 of the original drive — the closer the better.
  • Country of manufacture: Should be the same.

Marvell (version 2)

These encompass most newer and modern Western Digital drives.

Use the following criteria to find a donor drive.

  • Model number: It is ideal to match the whole model number, but if none is available you can try one that matches the entire first part of the model number as well as these three characters in the second part: WD1200BEVT-22A23T0
  • Heads map: Match the physical heads (PH) map exactly. It is OK if the donor has more heads than the original drive, but all heads before that should match.
  • DCM: Locate the J or 2 in the DCM. It should be towards the end. Make sure that the J or 2 as well as the preceding character matches on the donor.
  • Preamplifier: Exact match for both vendor and revision.
  • Microjogs: Each value should be within 200 of the original drive — the closer the better.
  • Country of manufacture: Should be the same.
  • Date of manufacture: Should be within three months — the closer the better.

<![CDATA[Donor Drives and ACE Laboratory Partner Up]]> https://www.donordrives.com/blog/ace-partnership/

Donor Drives Partners With ACE Laboratory

Donor Drives is proud to announce a new partnership with ACE Laboratory—the preeminent name in data recovery solutions. Both companies have a long history of being instrumental to the data recovery industry, and we’re proud to take that to a new level of integration.

This new partnership will help data recovery professionals work more efficiently. Purchasing donor parts is about to get a lot easier.

 

New PC-3000 Integration

ACE Laboratory is the maker of the hugely successful PC-3000, which is the gold standard for data recovery professionals. Their latest software update allows users to order directly from Donor Drives without leaving the PC-3000 interface. The model information you need will be automatically filled in so you can quickly search the Donor Drives inventory.

And since Donor Drives has the world’s largest supply of donor hard drives and PCBs, you can be sure that we will have just about whatever you need! If you're a frequent purchaser, you can also use your Donor Drives Rewards account to earn discounts off all the parts and tools you need.

 

How It Works

The new functionality facilitates the process of finding an appropriate donor for hard drives of all families. It is available in the “Utility Status” menu.

The “Search Donor Drives” function initiates the read-out of the vendor-specific parameters (Model, Manufacturing Date, MicroJogs, ROM F/W version, etc.) from a patient drive using the technological mode of a relevant PC-3000 Utility. In addition to that, the PC-3000 user can input such parameters manually.

All these parameters are further used for searching the appropriate donor drives. After you click the “Search” button, the PC-3000 Utility will open a new window of your Internet browser and will send a request with your parameters to the Inventory System.

The external (DCM, Product of, Site Code, etc.) and internal (SN, MicroJogs, Headmaps, ROM F/W version, Hardware revision components, Adaptive parameters, Preamp info, etc.) parameters taken from the PC-3000 Utility are passed to the Donor Drives Search Engine, which delivers the search result within a second, showing the suitable parts for your patient drive.

Currently, the “Search Donor Drives” function is available for the customers in North America, Europe and Australia. We are planning to broaden the coverage to a worldwide scale in the near future.

 

Future Developments

We will be expanding this partnership with ACE Laboratory further in the near future, to help data recovery professionals be even more efficient. Soon, you’ll be able to list your surplus donor inventory on the Donor Drives site through the PC-3000 software to generate revenue for your extra hard drives.

We look forward to more exciting announcements that will continue to change how the data recovery industry does business.

<![CDATA[The State of the Data Recovery Industry, 2014]]> https://www.donordrives.com/blog/future-data-recovery/ This is an abridged version of information originally presented in a webinar on December 10, 2014. If you would like to be invited to future Donor Drives webinars, sign up for our newsletter by scrolling down on this page and entering your email in the "Be the First to Know" form in the right column.

INTRODUCTION

The storage media industry is changing rapidly, and as a result the data recovery industry is adapting. Some have forecast that the industry has peaked, but new innovations are actually providing unprecedented new areas for growth. This article will spotlight the innovations and trends that are shaping the industry as we close out 2014.

 

WHERE THE INDUSTRY STANDS NOW

 

The data recovery industry grew at an elevated rate of 5-8% annually as the economic recovery began, from 2009-2013. That bubble has slowed back to normal growth of about 3-5% annually, which should continue for at least five years, according to projections from Gartner analysts.

Currently the data recovery industry in the United States generates approximately $4 billion dollars in revenue per year, employing more than 35,000 people according to Census and Labor bureau statistics—about 0.03% of the US GDP.

  

STORAGE MEDIA TRENDS

Solid State Drives are certainly becoming more affordable at a rapid pace, and thus, more common. IBM estimates that in 3-5 years we can expect cost parity between disk drives and flash memory.

In the past six years, SSDs have gotten as much as 17x cheaper per gigabyte. In 2008, we were looking at $7 and up per gigabyte, now we are down to about 40 cents per gigabyte, according to ACE Laboratory. In that same time, not only has the cost decreased, but the speed has increased, and read-write speed is now about three times faster than in 2008. So, they are getting cheaper as well as improving performance.

Disk drives, however, are not going away anytime soon, according to Steve Wojtowecz, IBM’s VP of Storage. Beyond that 5-year period, they may continue their dominance by making advances, such as the recent development of helium-enhanced drives that allow for capacity and speed improvements on very large drives without a different form factor.


Solid state drives have caused an uptick in cases already, mostly for erase verification since the majority of these drives are newer. But the growing prevalence of these drives in combination with HDD storage and backups, will cause continued increase in data recovery requests. For now, though, hard drive failure remains by far the primary impetus for data recovery cases.

Cloud storage is also growing rapidly, both as a primary storage medium and a backup solution. According to a study by TwinStrata, over 60% of companies use cloud storage in some capacity. Among those that aren’t, chances are good that their employees are: Cisco predicts that within three years, more than half of consumers will use a personal cloud storage account. And all companies know that not having a full set of data in one place makes recovery take much longer. If you backup most of your company’s files on tape, but many employees are using their own Dropbox or Google Drive accounts to store files, your recovery time in the instance of a disaster is significantly increased. That’s probably why among the companies not already using cloud storage, most plan to in the near future.

 

TOOLS & EQUIPMENT

ER-Tools is a somewhat new tools line for mechanical head stack assembly replacement. They’re going to be more advanced compared to any plastic Chinese tools you might find, but not quite as advanced as hddSurgery tools; however, they are more affordable than hddSurgery.

Furthermore, as far as equipment and software for recovery, the most efficient solution in our opinion is the PC-3000 by ACE Laboratory, still definitely the standard for recovering drives with logical issues and some physical issues as well. ACE Laboratory has also been on the forefront as far as SSD recoveries, which, as we mentioned, are a growing market. They have solutions where some SSD recoveries can be a matter of just a few clicks, which is great because, as you know, efficiency is huge when it comes to profitability for data recovery companies.

 

CONSUMERS

Customers have more and more data every year. To keep up with this, hard drives now have 500x the capacity they did a decade ago. Unfortunately, even with all this new data, users haven’t become much better at safeguarding it. 85% of users said they were “very concerned” about losing their important files; yet only 25% of them regularly back up their data from their computers. The automatic backups built into mobile devices make the picture much more favorable for them. Currently, solid state drive uptake is more common among home users than enterprise users. 

 

ENTERPRISE CUSTOMERS

Data recovery is not going anywhere as a service to the business industry, either. In a Ponemon survey of American healthcare, finance, and government organizations, 85% said they use third-party data recovery services. This is actually up 6% from the previous year. As a major note, 39% said they use third-party data recovery services once a week or more!

While cloud storage is growing in popularity, Twinstrata found that 50% of companies still use on-site backups. For 10% this is their only backup. Hybrid storage solutions (on-site and cloud) are generally becoming accepted as the standard.

Furthermore, as companies with lots of data embrace Bring-Your-Own-Device policies, cloud and smartphone recoveries will become a larger market. Larger companies will shift further towards virtual environments to accommodate various devices. VSAN can be incredibly complex, which complicates recovery. One drive can fail, necessitating recovery on not just that drive, but other interconnected drives in order to rebuild the storage pool. So, if you have the resources, recovering virtual networks is a rapidly growing market to tap into.

 

AUDIENCE QUESTIONS

How do you deal with data recovery from helium hard drives?

These are enterprise drives that we have not yet come across. Some of the larger companies have begun to test recoveries on them, and claim they are able to successfully recover them, but it requires very stringent care and cleanroom standards. I don’t believe there have been many cases yet, and there won’t be for quite some time.

 

How do you get certifications from HDD manufacturer companies?

There are various programs available depending on the manufacturer. Some, like Western Digital just request information about your company and your services to review. Others, like Apple, require specific training programs you can pay for. Seagate is an exception, as they offer their own proprietary data recovery service, so they don’t offer much in terms of third-party certification.

 

Any comment about recent problems with Seagate DM001 and DM003 models and new solutions for these?

Mostly, our clients run into firmware and mechanical problems with these drives. When it comes to firmware, these are mostly typical failures that ACE Laboratory solutions can assist with. As far as mechanical failures, many end up having permanent platter damage and are not possible to recover, so be very careful when doing the initial diagnostics.

 

Any thoughts on the renewed popularity of tape as a backup medium?

Gartner famously predicted that all tape backups would be done by 2011, which has obviously not come true. Understandably, tape backups are economical, and many IT professionals are very familiar with them, which can be seen as a benefit to businesses. Personally, we are proponents of a hybrid backup structure for those for whom it is feasible—offering the advantages of on-site backup (whether tape- or disk-based) with the advantages of an off-site or cloud backup.

 

SSD Recovery seems to be more difficult. Will SSD drives be more standardized in the future and make recovery easier?

In the past year, several general storage media companies have purchased and merged with SSD manufacturers, which should give way to a bit more standardization. For the time being, SSD recovery can sometimes actually be easier than recovering a hard disk drive. Currently, the industry standard, and what we personally use, is the PC-3000 SSD, which works with dozens of manufacturers and a variety of interfaces (SATA, PATA, mSATA, M.2/NGFF).

 

How about recovery of smartphones and tablets?

It depends on the file system and other factors. iOS recovery in general is essentially a USB-interfaced SSD (NAND) recovery, much like a simple flash drive, but newer devices, such as the iPhone 5 and newer models have different encryption that can be difficult. Apple does offer Apple Technician Certification. Luckily, iOS devices are often automatically backed up to iCloud, so recovery in the traditional sense is not necessary.

Many Android devices split their storage between an SSD and an SD expansion card, so you will need to be able to recover both of these interfaces. There is also consumer-level data recovery software available for download for Android that solves most basic issues.

 

Are there alternatives to PC-3000 for SAS and SCSI?

Not really. You can check out the PC-3000 solution for these, and it does offer the widest compatibility we’ve seen.

 

We've seen a larger amount of multi-disk NAS devices in 2014, do you see this trend increasing in 2015?

I think it will. We will see more NAS drives and RAID arrays as the technology keeps getting cheaper and awareness spreads. For example, Western Digital recently announced they’ll be expanding their Red drives for home or small office NAS. They now have up to 6TB NAS-specific drives supporting up to 8 bays, and the storage is as cheap as $0.04 per GB. That’s going to appeal to a lot of people.

 

What are your thoughts about Visual Nand Reconstructor?

We haven’t had a chance to test out ruSolut’s Visual Nand Reconstructor ourselves yet. Their hardware is similar to readers and adapters already out there, but their software looks pretty unique in its approach to logical image reconstruction.

 

As a parts supplier, how do you foresee dealing with the shortage of HDDs as storage moves to flash?

As we mentioned earlier, there is definitely a storage shift occurring, but thankfully, it is happening gradually. Furthermore, we have customers worldwide, but the majority of our business is done in North America and Europe, which, all trends indicate, are moving more quickly towards flash memory than other parts of the world. So, manufacturers will continue to produce hard disk drives for markets like South Asia and the Middle East after the market here has shrunk, which is great for us as secondary-market donor drive resellers.

Currently, we have more of a challenge acquiring enough SSDs and Flash drives to keep up with demand, but as costs decrease and uptake increases that should even out as well.

<![CDATA[A Guide to RAID for Individual Users]]> https://www.donordrives.com/blog/raid/ RAID storage has been around for decades, but those who have heard about it or who use it often think it is only for enterprise users and wouldn’t be practical or useful for an individual. However, recently, more and more individuals are embracing the advantages in speed and protection offered by RAID.

hard disk drive and solid state drive
Two drives that could be used for a Hybrid RAID solution

What is RAID?

RAID stands for Redundant Array of Independent Disks. As the name might imply, you are using multiple storage drives to store your files. The “redundant” part means that your data will be saved in multiple places on these different drives. The computer will view this RAID of multiple drives as a single drive. A RAID can be created of any storage drive, but, for individuals, a typical setup would consist of 2 to 3 hard disk drives (HDDs), 2 solid state drives (SSDs), or one drive of each type. HDDs and SSDs each have their advantages, which we discussed in a previous blog post.

Advantages of RAID

RAID offers advantages over a single drive, including speed and protection of data. Depending on the configuration you choose, you will opt for either more speed or more protection. There are some additional limitations, including hardware-based: you will need to install a RAID adapter if your motherboard is not pre-configured for RAID.

Popular RAID configurations

RAID 0RAID_0 by User Cburnett

RAID 0 splits your data onto multiple drives, which the system will read as one. Here you will have the advantage of increased storage (up to the combined storage capacity of the drives you are using) and increased speed. The downside is that your chances of disk failure are increased since if even one drive fails, most of your files will not be accessible.

This configuration spreads the data equally among the drives, even splitting individual files. RAID 0 can be used with any number of drives, but the most common applications for an individual would be two HDDs or two SSDs.

 

RAID_1

RAID 1

RAID 1 mirrors your data onto multiple drives. Again, this will typically be two HDDs or two SSDs. One drive will act as a sort of “backup” of the other. If one drive crashes, the other can be read from without issue.

This option will not increase your storage capacity or read/write speed, but can be helpful as protective measure if you can’t afford to lose your data, but keep in mind this should not replace a traditional backup.

 

 

RAID 5RAID_5

RAID 5 works as a sort of middle ground between RAID 0 and RAID 1. This is one of the most popular RAID applications for businesses due to its versatility. It requires at least three drives. These can be HDDs or SSDs, but HDDs are more common for an individual due to the cost of using 3+ SSDs. RAID 5 works by splitting your files among multiple drives, similar to RAID 0. This gives you increased storage and read/write speed (not quite as much as a RAID 0 configuration, though). Your file will be split among all but one of the drives, and the final drive will hold a redundant copy of part of the data ("parity"). In the diagram to the right (containing four drives), that is represented as your file split into parts 1, 2, and 3, plus a redundant "p" parity. That way, if the first disk crashes, file "A" can be opened by using parts A2 and A3 in combination with the parity (Ap) to figure out what was in A1. If this happens, it will considerably reduce your speed, though.

Hybrid RAID

Hybrid RAID consists of an equal number of SSDs and HDDs in a RAID 1 configuration. Files are written to an SSD and a mirror HDD. Files will only be read from the SSD if possible. As SSDs are generally faster than HDDs, you have increased read speeds, while having the mirrored file protection that comes with RAID 1.

Great! How do I get started?

First, determine the RAID configuration that best suits your needs. Next, check out your hardware needs. Get the storage devices you'll want to use. You can use your current hard drive plus one or more new ones, provided they're larger than your existing one. Or you can set up a RAID with all new drives. Also, make sure your motherboard is enabled for RAID. If not, you'll need to get an adapter. If your motherboard does already support RAID, note that not all the connections on the motherboard necessarily do. Read your manual. Now you're ready to go! Set up your RAID in the BIOS. Lifehacker has a step-by-step on how to enable a RAID 1 mirrored array. You can make adjustments for the configuration you want. Also, keep in mind, not all systems will be exactly the same.

Note: RAID is not a backup replacement

As you can see, RAID storage can increase your storage capacity, your I/O speed, and your protection against hard drive crashes. But even if you are using a RAID option that provides such protection, like RAID 1, there are many ways to lose data besides a hard drive crash. If something such as a fire or virus harms one of your RAID drives, it is likely to affect all of them. That’s why it is important to also have a proper backup, either in the cloud or on an external drive.

<![CDATA[HDD vs SSD - How to Decide]]> https://www.donordrives.com/blog/hdd-ssd/ One of the most common questions we get at Donor Drives is, “HDD or SSD?” A quick Google search would indicate that everyone should transition to SSD, or Solid State Drives.  The truth, however, is more complicated than this, and you should consider a number of factors when making this decision, whether purchasing a new computer, building your own, or purchasing external storage.

A hard disk drive, or HDD, is the traditional storage device for computers.  It operates with quickly spinning disks coated in magnetic material which store your data. An arm reads and writes the data onto these disks.

A solid state drive, or SSD, is a slightly newer iteration of storage device that has gained popularity over the past few years. SSDs do not have moving parts like the disks in an HDD. Data is stored in stationary chips, much like a more advanced external USB or flash drive.

Solid state drives offer certain advantages, such as faster operating system boot time, meaning you can get to work sooner after starting up your computer. Additionally, thanks to having no moving parts, the sounds associated with a spinning disk are absent, and the power used is much less substantial. Also, unlike a traditional hard disk drive, magnets will not wipe your data if they come too close to the drive. These are some small advantages, but they can be very important to power-users who need to open large files quickly, and need battery life to be extended.

HDDs on the other hand offer two large advantages: cost and storage size. For comparable capacity, an SSD can cost three to five times as much as an HDD. And, speaking of capacity, currently SSDs do not offer the storage capacity of higher-end HDDs. (As ExtremeTech reports, Seagate recently began shipping an 8TB drive to enterprise customers. The largest available SSD is half that size but costs much more.)

The question is getting even more complex as some of the generally accepted benefits to each camp are beginning to be questioned. Some say SSDs run hotter and use more energy than HDDs at high performance levels. And the large lead HDDs had in storage capacity is quickly closing.  

In the end, consider your storage needs, your budget, and your usage. Those who need quicker performance may want to go for an SSD. Those who are need a very large storage capacity or who are more cost-conscious and don’t need the relatively minor speed improvement may consider a traditional HDD.

<![CDATA[Forbes Features Data Recovery]]> https://www.donordrives.com/blog/forbes-data-recovery/ This week, Michael O’Dwyer wrote an excellent article on Forbes.com entitled “How Not To Lose Your Head When You Lose Your Data”.  As he notes, “PC users, almost without exception, are experienced with data loss.” This is an unfortunate reality of computing, but he does mention some important solutions.

If possible, the “goal should be disaster avoidance not disaster recovery”.  Creating a backup of your data can help avoid the stress of data loss in the unfortunate case of hard disk failure. The article suggests regular, automatic backups, such as our Unlimited Automatic Cloud Backup (now on sale for $14.99/mo).

Should you find yourself without a suitable backup, there are other options. You may be able to repair your failed hard drive and extract the data from it. (For advanced technicians we have a guide to PCB replacement and offer plenty of hard drive parts and PCB components for sale.)

If doing it yourself is a bit daunting or the failure is too severe, you can send it to a professional data recovery service, such as Outsource Data Recovery. They offer a $60 hard drive repair service, after which you can extract your own data. If this is not possible, they also offer full data recovery service – you can get a free instant quote by filling out some information on their website.

As the Forbes article says, in our computer-centric world, we all have data we would hate to lose—whether important business documents or priceless family photos—but we increasingly have options to protect or recover our lost data.
