2TB Western Digital 2nd Opinion

Hard Drive Data Recovery

Case Study

Drive: WD20EARS-00MVWB0
Problem: Clicking. Previously diagnosed by a third party as unrecoverable due to media damage.

We are always keen to test our services against our competitors, just to make sure we’re still up there with the best of them. When we heard from one of our service partners (ABC Rawpaw) that one of the top ranking data recovery companies on Google had given up on a customer’s drive, we were curious to take a look. It’s also worth mentioning that the client had paid £234 to the other company, despite them recovering no data.

Third party report

We received a copy of the original diagnosis report with the hard drive. The report mentioned incorrect head alignment and also damage to the head assembly preventing the drive from functioning correctly. It also stated that they had subsequently replaced the old heads with new ones but due to suspected disc damage, recovery was unsuccessful. A plausible enough report, but was it accurate?

Booking in

The drive was booked into our process. We noted that the warranty seals had been removed and the top cover showed signs of being previously opened. Whenever we receive a drive in this state, we always want to make sure the drive has been rebuilt correctly. We need to do this in our cleanroom to prevent any contamination getting in from the air. Our office is clean, but it’s no place to open a hard drive.

Findings

The inside of the drive was examined in our cleanroom and found to be spotlessly clean. There were no signs of disc damage or particles, but we did notice that the screws were not factory-tight, suggesting previous work had taken place. Happy that there was nothing untoward inside the disk, it was rebuilt for further diagnosis. The drive was powered on and initially failed to reach a ready state. This is common for Western Digital drives as they often have firmware corruption. We used our proprietary firmware tools (and John’s keen knowledge) to repair some of the firmware area of the drive which then allowed the drive to reach a ready state and allow access by our imaging tools.

Imaging

We did find that one of the heads was not performing within spec, but we were able to work around this, again using specialist tools. After imaging the majority of the drive we replaced the heads to allow better access to the missing areas. This helped improve the amount of successfully recovered data.

Result

We ended up with over 800GB of data recovered from the drive in good condition, even though one of the biggest companies (according to Google) was unable to get anything! This is not the first time we’ve recovered data where others have failed, but we always wonder how many people give up on ever seeing their data again, even though it may be recoverable with the right knowledge.

In the end we had an extremely happy customer (and service partner), and were able to test ourselves against one of the biggest data recovery firms in the UK. A great result for us that shows the importance of getting a second opinion.

Why Choose Dataquest

Safe Data Recovery

When your hard drive has failed, where do you turn for help? In many cases the supplier or manufacturer of your computer or hard drive are not the best place to deal with your data loss. Also your warranty only covers the hardware and not your lost files.

So why choose us at Dataquest ?

With over 15 years of experience we are very familiar with all types of hard drive failures. Unlike many other companies our costs are fixed and based on how quick you wish to have your recovered data returned. Like many other companies we offer a free diagnosis, but unlike many others this does not determine eventual recovery cost but decides wether the hard drives problem is mechanical or not. We use the latest hardware and techniques to produce the best results possible.

On a more personal note customer service is a large part of what we do and understanding customer needs is paramount. We will in many cases go beyond what other companies would deem cost effective when recovering lost data. We use all our acquired knowledge to exhaust all possibilities.

We are also partnered with many IT support companies around the UK, to enable us to connect with customers who would other wise have not known of our services.

PGP Whole Disk Encryption

What is Hard Drive Encrytion

PGP WDE is an encryption tool that uses a boot loader installed on an internal hard drive. This utility launches before Windows and prompts the user to input their password. Without the password you cannot gain access to the data.

This utility is widely used by IBM personnel and is now part of IBM’s  process that has to be adhered to by end users. Prior to this utility IBM hard drives were restricted access by a low level ATA hard drive password setup  by the internal IBM IT department.  As computer systems advanced and maybe as a result of a reduced IBM IT department,  IBM adopted the user friendly PGP encryption process.

We regulary receive these hard drives from IBM, and we find that the major problem is related to the PGP boot sequence. PGP does not like a hard drive that is suffering from bad sectors, especially within the partition table. It results in the user being unable to load their access code on startup, or in some cases the code is accepted but does not boot correctly due to bad sectors further along.

We have a lot of experience recovering data from PGP whole disk encrypted hard drives and as a result our data recovery process has a very high success rate.

Mavericks (10.9) Western Digital Data Loss (UPDATED)

Portsmouth & Southsea Mac Support

We’ve been hearing reports of data loss with certain external hard drives after an upgrade to the latest Mac operating system Mavericks. The blame seems to fall to the disk management software that Western Digital bundle with their external hard drives. In response WD has removed WD Drive Manager, WD Raid Manager, and WD SmartWare from their website until they figure out the problem.

We have already had first-hand data recovery enquiries for such disks, so it remains to be seen if these issues can be resolved, or if the data is permanently damaged. One notable case involved a 6TB RAID with two 3TB drives in a mirrored array. After the update to Mavericks, the volume appeared as an empty 3TB drive.

It’s worth noting that even if you use a Western Digital RAID drive set as a mirror, this problem can still cause data loss. Both disks in the mirror are susceptible to the same problem. Remember that RAIDs need to be backed up even more than single disks!

Update – 8-11-2013

We’ve now completed the recovery process for one of these hard drives. It appears that the drive we received had been formatted to an empty MyBook volume. The way the Mac filesystem stores data means although most of the files can be recovered, it is not possible to restore the original file and folder structure. This causes issues for files like InDesign which link to external files by name when you add graphics to the document.

We’ve not yet seen enough of these disks to know if this is a common outcome for all affected disks.

What To Do When You Run Out Of Space

It’s a common problem that as we generate more data each year we start running out of space to put it. This is now even more of an issue in the smartphone market, where built-in cameras are generating increasingly large photos and videos, without providing much in the way of additional storage. The most common iPhones are still 16 & 32GB but the photos they now produce can be megabytes in size, with videos easily reaching 1GB.

What To Do When You Run Out Of Space
What To Do When You Run Out Of Space

It’s tempting to take that data and put it somewhere else, so either a laptop or external hard drive. Then once you’ve copied it all you delete it from the phone and gain back all that space. Problem solved.

Not So Fast…
If that copy on your laptop is now the only copy, then you could be one spilt coffee from disaster. If the laptop goes up in smoke, gets stolen, dropped or any of the myriad other ways of failing then it’s bye bye data.

The Fix

The key to making backups is redundancy. The key to making backups is redundancy. The key to making backups is redundancy.

You need to make extra copies of your data to different types of storage. This could be an external hard drive, NAS, USB Pen, SD card, anything. But don’t just pick one of those. Make a few backups. Put one in a locked safe somewhere. Send photos off to the cloud. Store a copy of your music at your nan’s house. If any of those copies gets lost or broken you can just replace it with another copy.

So let’s run through an example. All those photos on your iPhone have filled it up. Here’s what I would do:

  1. Copy the photos to my computer. Check them.
  2. Backup the computer as usual. (You’re already doing that, right?)
  3. Make another backup, or copy the photos to an online storage service like Dropbox.
  4. Now it is safe to delete the photos from the iPhone and revel in all that fresh space.

Note: Deleted photo recovery is virtually impossible for all modern iPhone versions due to encryption. 

Here’s another example for when your computer runs out of space instead:

  1. Is it possible to upgrade the internal storage? If it is then you should do that.
  2. If this is not possible, or too expensive then you will have to get creative. It will be more fiddly but copy all data to two external hard drives.
  3. You always want to avoid just leaving your data in one place. All electronic devices can (and will) fail, and they have a terrible habit of doing so at the worst possible moment.

So, just remember that no single copy of your files are safe. Making extra copies is cheaper and easier than waiting until something fails.

Maxtor DiamondMax Clockwise Discs

You have heard of the myth about water behaving differently from the northern hemisphere compared to the southern hemisphere. Especially when draining water out of a sink or bath. Well apparently this is a myth and not fact.

So what has this got to do with hard drives? Well the same was said about some of the old Maxtor hard drives and why they were built with clockwise disc rotation. Where they built for the southern hemisphere market and do they work as well in the northern hemisphere. Built in mid 2000 the Maxtor DiamondMax 10 hard drives were designed to spin in the opposite direction to the conventional mechanical hard drives.

I could not find any information as to why they were built this way and whether this design did improve performance depending on location in the world. Maybe this question will never be answered.

See pictures below of a the internal working of a conventional hard drive compared to the Maxtor DiamondMax 10 hard drives.

Time Machine Must Create A New Backup For You

Time Machine must create new backup for you
Time Machine must create new backup for you

The other day I got an error message from Time Machine that it wanted to start from scratch with the backups on my Time Capsule. As I only use the Time Capsule as one part of my backup routine that was no big deal. I made sure my other non Time Capsule backups were up to date and then clicked Start New Backup. But what if the Time Capsule had been my only backup? I’d have been running without a backup for as long as Time Machine takes to backup my machine from scratch. Somehow I’ve trimmed my work laptop down to 78GB but it still estimated 6-14 hours until completion. (Yes, over wireless. No, I can’t relocate my office for the day.) What if my laptop died in that time? I’d have a dead laptop, a deleted Time Machine backup and an unfinished Time Machine Backup. In other words I’d be stuffed!

Now don’t get me wrong, I think that Time Machine has been brilliant in getting people making regular backups and I applaud the ease of use. The problem I have is that the language they use in their warnings is not strong enough. People should be more scared of losing their precious family photos or business files. There’s no need to sugar coat it. Also instead of deleting the old backup first, Time Machine should start a new backup and then delete the old one after the new one is verified. As long as there is enough free space of course. In my case there was plenty of free space.

I have included the original warning text below, along with my own version. I’ve not gone totally overboard, and sure it could use some work, but little details like this could really costs somebody some important data. It’s worth spending some time on.

Original Message Text

Transcript: Time Machine completed a verification of your backups on “Time Capsule”. To improve reliability, Time Machine must create a new backup for you.

Click Start New Backup to create a new backup. This will remove your existing backup history. This could take several hours.

Click Back Up Later to be reminded tomorrow. Time Machine won’t perform backups during this time.

My Version

Time Machine must create new backup for you. Fixed
Time Machine must create new backup for you. Fixed

Transcript: Time Machine has found a problem with your backups on “Time Capsule”. First backup any important files, then click Start New Backup. This will create a new backup and then delete the old one. This could take several hours and you will be at risk of data loss until it completes.

Click Back Up Later to be reminded tomorrow. Time Machine won’t perform backups during this time.

Notes

There are a few interesting things to point out here. As you are starting from scratch with the backup, you lose any old versions of files that Time Capsule had stored. It’s bad practice but some people will happily delete files from their computer, safe in the knowledge that Time Capsule has a copy. In that scenario, deleting the backup would be a disaster!

I still don’t know exactly what caused the problem with my Time Capsule backup, but since starting again I haven’t seen that message.

Data Survival Guide Mac

Many hard drives we see have been more damaged by a failed recovery than they were in the first place. We have released the Data Survival Guide to help people avoid some of the common mistakes. This first version is for Mac users but we have more on the way.

Why not print this out and keep it in your laptop bag in case of emergency!

Troubleshoot Buffalo External Hard Drive

Like most external hard drives, Buffalo external drives are simply a wrapper around a regular hard drive. Aside from the protective shell they also have some electronic parts to convert between the internal hard drive and the external USB, Firewire, eSATA or Thunderbolt connections.

If you have problems with an external drive, you can perform a relatively simple test to check where the fault lies. Be aware that opening the external drive case will probably void your warranty, and if there is crucial data on the drive you should seek professional data recovery. That’s the obligatory warning out the way, so lets have a look at some troubleshooting.

Troubleshooting tips.

  • First check all cables are plugged in securely, and not damaged or frayed near the ends.. If you have an identical drive with spare cables try them, but make sure you don’t plug in a power supply with different voltage! Hard drives don’t handle extra voltage well so you’ll end up in a worse position than you started.
  • If you know how, you could remove the hard drive from the external case and attach it directly to a PC to see if that allows access to the data. If it does, you should copy the data off straight away. The drive could still be faulty & fail again soon.
  • Whatever you do, don’t dismantle the actual hard drive. Hard drives are built in controlled clean-air environments and even the smallest spec of dust can cause permanent damage to the drive.
  • Since the introduction of unique ROM chips on the hard drives, it is often no longer possible to exchange circuit boards with another hard drive to access the data. In our experience circuit board problems are far less common than they used to be.

HTS5450 Second Generation

Now in a new 7mm slimline form factor, and Advanced Format specification, the HTS5450 hard drive is proving a popular choice for vendors with limited space. The drives are especially popular in Ultra thin laptops and slim portable external cases. Now being manufactured by Western Digital under the brand name of HGST, the 500GB boasts just a single media platter to store all that data. Part of the redesign also brings Advanced Format to these drives. Certain older operating systems such as Windows XP require the use of the HGST Align Tool provided by Western Digital. Users of the latest OS X systems and Windows 7+ do not require the use of this Tool.

Advanced Format has been introduced to cram more data on a single platter. To do this the manufacturer has increased the standard 512 byte sector size to a 4096 byte sector. This format design also incorporates better data integrity, hopefully giving the customer all round better performance and reliability.

If you’ve lost data from a HTS5450 drive, try our Hitachi Data Recovery Services to get your data back.

Remember, electronic devices can malfunction at any time, so make sure you always backup your precious data.
