Old Industrial Equipment Data Recovery

Old Industrial Equipment Data Recovery

It’s always interesting to see how a complex manufacturing line can be run from such old hardware. In this case we were sent a custom PC from a  machine that is used to fill and cap bottles.

The first problem was trying to get the case open to remove the hard drive. There is no ifixit guide for this thing!

Inside I found a 20GB Seagate laptop drive (dated 2007) running Windows 2000 along with the programs that control the machinery. The hard drive was connected to a proprietary motherboard that in turn connected to the machinery via serial ports.

In this case, data recovery was not enough. What the client needed was a full working copy of the failed disk to reinstall into the system. The aim was to get the kit up and running and return it to the customer so they could carry on with work as soon as possible.

We’re set up to handle exactly this sort of problem, so I got this recovered and returned within two days.

The Worst Head Crash Ever?

Worst Head Crash Ever
I’ve seen some pretty serious head crashes in my time. It’s the worst part of my job, knowing I’ll have to tell someone their data is gone forever. Sometimes media damage can be subtle enough that it’s impossible difficult to even detect by eye. Other times the damage is obvious. Today was one of the clearest I’ve ever seen. What’s worse is that we got two of these identical disks from the same Mac Pro, with identical damage. You have to see it to believe it…
Worst Head Crash Ever?

It’s difficult to know how long these damaged disks were left spinning, but it looks like months! If you look closely, you can see that the centre of the disk is worn right through. That black dust everywhere was once the shiny disk surface that stored the data.
 
It’s worth mentioning that nobody in the world that can recover data from disk dust. The easiest way to avoid such serious damage is to power off your hard drive as soon as you hear clicking. If we got these disks sooner it’s possible we could have recovered them.

Seagate Barracuda Ramp Weakness

Seagate Barracuda Ramp Weakness

During a recent RAID 5 recovery attempt, John made an interesting discovery inside the two failed disks. The plastic ramp that the heads park onto when idle had snapped in the same position on both drives. We don’t know if the heads got damaged first, and then broke the ramps during parking, or if the ramps broke first, damaging the heads as they parked. The client told us the disks were not dropped or jolted. Whatever the cause, both disks had scratches to the delicate magnetic surfaces. In this case, two failed disks from a four disk RAID 5 means the data recovery is not possible.

Old vs New

The other two disks in the RAID had different firmware and don’t show the same fault. We don’t know if these disks have the other (older?) more robust ramp system that we’ve seen in similar disks.

These ramp problems are the latest in a long line of faults for Seagate.

Interestingly, the surviving disks in this RAID array were dated 2013, and the failed disks 2014. I would have expected the older disks to fail first.

Seagate SSHD ST4000DX001 Data Recovery

I previously posted about a Seagate SSHD ST500LM000 hybrid hard drive which failed to spin. This hard drive was put into our R&D process due to the type of the failure and further analysis confirmed that the problem was relating to the Solid State part of the drive. At the time I had only seen this type of failure with the Seagate Thin SSHD laptop drives. But since then we have now received Seagate desktop SSHD hard drives with the same type of failure.

Because the SSHD hybrid drives are a cheaper option to SSD drives I am seeing more of them in for data recovery. Also as these are still mechanical hard drives, I am seeing many of the same failures as I do with standard hard drives. For example Electronic Faults, Dropped Drives, Water Damage etc.

Top 3 Coffees in Portsmouth

Safe Data Recovery

It’s probably worth a quick explanation here. Why is this data recovery blog so interested in coffee? Well personally I love coffee, but I also often recover data from hard drives that have been for a drink (or a swim). So there’s my excuse, now back to the coffee!

Fortunately for caffeine addicts in Portsmouth like me, there are plenty of places to get your fix. I’m the sort of person that finds somewhere I like, and then just keeps going back there forever. Sometimes though, it’s worth having a look at the other options. My current top three places for coffee in Portsmouth are below in no particular order. I’ve chosen three, but I’m always happy to try more places so let me know if you’d like me to give your coffee a try!

Portsmouth Coffee

Coffee#1

Coffee#1 is a small chain of coffee shops spreading like wildfire from Wales, across the South West, all the way down to the South Coast of England. The local branch is in Palmerston Road, Southsea. They do great snacks, cakes & lunches (Sausage & Relish roll anyone?) I usually go for whatever single-origin coffee they have in, and I’m never disappointed. They also have beans & equipment for sale. I recommend the Brazillian beans if you can get them. They are my current favourite for grinding & Aeropressing at home. Visit the Coffee#1 Website

Home Coffee

I’ve only just found out about this place, but I’m so glad I did. I recently went for lunch here & had a big granary doorstep sandwich, an Americano, & an iced ring doughnut. I couldn’t have been happier with all those things.  The cosy shop on Albert Road is just a few steps away from the Kings Theatre, but they are set to open a new store on Cosham High Street, much closer to home for me! They have lots of info about their coffees on the blackboards and are more than happy to have a chat with you about brewing at home. They sell kit & beans too which is handy, although I’ve not tried the beans myself yet.(Update – The beans are great!) Visit the Home Coffee Website

Soprano’s

A bit of a wildcard entry here, and also a hearty recommendation if you like quality fresh Italian food. The Peroni on-tap is always delicious, and their after-dinner coffees are the perfect way to finish a meal. Booking is advised as the cosy restaurant is always bustling with customers whenever I’ve been there. Visit the Soprano’s Wesbite

So there you have my top three coffees in Portsmouth. If you’ve spilled coffee, or any other drink on your hard drive or computer, get in touch. We can help recover the data, and you can tell me if the coffee you spilled was any good!

Another Successful Dropped Hard Drive Recovery

No Chance Data Recovery

Last week I was working on another dropped hard drive recovery sent into us by one of our Data Recovery Partners. I immediately took the hard drive into our clean room and removed the top cover for internal inspection. Although the hard drive had been dropped there were no visible signs of physical media damage. I replaced the damaged internal heads, rebuilt the hard drive and successfully recovered the data for the customer and Partner.

Thankfully the partner had advised the customer to stop trying to access the hard drive as described in our blog. When they received the hard drive from the customer.  They sent it straight to us, without attempting anything themselves.
These actions by the customer and partner were critical in the eventual successful outcome.

Hard Drive Data Recovery

Despite offering world-class data recovery from our workshop here in Portsmouth, we understand that sometimes, the data just doesn’t justify the cost of getting it recovered. If you’re going to go it alone and attempt a DIY recovery, we’ve got some handy tips to avoid making things worse. It might be a good idea to print this page to use as a reference. Also feel free to comment at the end of the post if you’d like any questions answered.

Stop Using Your Hard Drive

If you want to recover data, you can’t do it from the disk you want to recover from. When you boot up a computer it writes data to the hard drive. Even browsing the web or checking e-mails writes little cache files to the disk, potentially overwriting the files you want to recover.

Set Up

You ideally want to work from a different and reliable computer, have plenty of storage space for recovered files, and make sure everything is ready before you attach the faulty disk. You don’t always get a second chance with hard disks, so make sure you’re ready to grab the files if they appear.

Now You See Them

If you suddenly gain access to the files, copy them to another drive as soon as you can. The disk is unlikely to have repaired itself, so this might be the last chance to copy the data before if gives up completely. Take the most important files first. If the copy gets stuck, stop it straight away as the disk could be causing damage.

Watch The Clock

If you decide to try DIY recovery, keep a close eye on the time. If the estimated time keeps increasing it could be a sign of disk trouble. Failure to deal with that could cause the drive to fail completely, and beyond repair (even for us). As a guideline, it should take no longer than a few hours to copy a whole 1TB disk over USB 3.0. If your estimate says much more than that, or keeps going up in time, it could be the disk getting worse. Maybe try copying important files in small batches first. Data Recovery Time Remaining

Priorities

Your priority with a failed drive is either to make a copy of the disk, or copy off the files as soon as possible. Don’t try to scan, repair or fix any errors. A failed repair can completely damage your files beyond recovery. This means don’t ever use spinrite, diskwarrior, techtool, or any other diagnostic tool until after you’ve extracted the data. Some people report success with these tools, but it’s far safer to copy the data first, and run those tools later.

Restore or Reinstall?

Don’t re-install or restore the computer. At best it will overwrite some of the data. At worst it will overwrite all of the data and leave you with a factory-fresh (blank) version of Windows. If you’ve already done this, we can often get data back, but it won’t be as complete as a normal recovery.

Brrrr It’s Cold in Here

Never ever put a hard drive in the freezer. Although this trick is a common part of data recovery folklore, it is likely to do so much more damage than good. We have never used any type of freezing process for data recovery, and neither should you. Leaving your hard disk unplugged for a day is likely to be just as successful, and won’t risk contaminating the delicate disks and heads. Hard disks are not air-sealed so even if you put them in a sealed bag, they already have moist air inside them which can freeze and then cause condensation.

Stop Hitting Yourself

If you saw how delicate the inside of a hard disk was, you’d never consider hitting, tapping or knocking it. Even if you did manage to dislodge some stuck heads, you’ll probably either rip them off, or take a chunk of the disk with it. There are careful ways to remove stuck heads, but they cannot be done at home.

Keep it Together

Never dismantle a hard drive. This is a case when the “no user serviceable parts” label really is true. Not only are disk internals extremely delicate, they have an air filter in the cover to stop particles getting inside the disk. If you remove the cover, all sorts of dust and lint can get in. Dust particles are bigger than the gap between heads & disks, so they can cause the heads to crash into the disks and scrape off the magnetic coating. Once the coating is gone, the data is gone.

Good Luck

If you decide to try DIY data recovery, good luck, and be careful. If you’d rather let us look at the disk instead, get in touch.

When Backups Go Bad ~ Revisited

I was recently going through some old posts on here, and found the one with the clickbaity headline When Backups Go Bad. Despite the title, I thought it was worth looking again at some of the common ways backups can go wrong. A bad backup can be as useless as no backup at all. There is an old phrase that applies perfectly to backups. “One is None. Two is One.”

RAID Instead of Backups

This is a common one. Although RAID can protect against some hardware failures, it does nothing to protect against corrupt partitions, virus attacks, accidental deletion, formatting, multiple disk failures. The list is endless. Add to this the fact that you can have 12, 24, even 48TB stored in one massive array, and you stand to lose an awful lot of data in one go if the whole thing goes south.

Same Disk, Different Day

There are ways to partition a disk so it appears to the computer as multiple disks. The danger is, if you don’t know there are two physical disks inside the computer, you could be making backups to the same disk. When it fails, both partitions will go with it. Best backup to an external drive and then you know for sure.

Break the Encryption

Encrypting any data is risky without careful consideration. By design, your encrypted data is not accessible without the password, or perhaps a recovery key that was created during the original setup. If you don’t have either of those keys, you can wave goodbye to the data.

Inbetweener

If you’re ever left with a single copy of your files, you’re on thin ice. If something goes wrong, you’ve lost one copy of the data already. We always suggest multiple backups for this reason.

The Space Maker

New computers can have painfully small storage, (hey Apple) so a common solution is to start dumping files off to an external disk. This is fine if you just move over replaceable movies & music, but you have to be prepared to never see those files again. Don’t store all your photos & documents on an external drive unless you keep another copy somewhere. External disks are no more reliable than internal ones and can fail at any time. If anything, the risk of dropping or losing an external drive is higher as they are so small and portable.

I’m sure there are more ways backups go bad. I could probably make this into a regular feature. Remember, when it comes to backups One is None, Two is One…

Back up as much of the data as possible and replace the disk. See an authorised Apple dealer for more information.

S.M.A.R.T. Status : Failing

If you see the message above, your hard disk or SSD has started to fail and has reported faults to the Mac. If caught early enough, these disks can usually be recovered. You can try to copy important data to another disk but if the copy process gets stuck for a while, it’s safer to stop. If you leave a failing disk in that state it can deteriorate until the disk is ruined.

If the data is really important, and you’d rather not take the risk, you could have a look at our Mac Data Recovery Services. We have been dealing with these sorts of problems for years and have a developed a really safe way to get the data off in good condition.

This drive has a hardware problem that can't be repaired

Whatever you decide to do, don’t ignore this message. The broken disk cannot repair itself, and will only get worse. In many cases, the disk won’t even be readable by the time you see this warning.

It doesn’t matter if the disk is still inside your iMac or MacBook, we can remove it for you, and even replace the drive at the end of the recovery process if you want. Ask about our Mac Setup service if you are interested.

Successful 8 Disk RAID Recovery

This was a RAID recovery with a challenge. The customer could only find seven of the eight disks from the RAID and two of them were not accessible. To make the challenge even more difficult, the customer did not the RAID level or any of the configuration. All we knew was the disks were from an old Dell Server.

The RAID Recovery

We first managed to overcome the failed disks and imaged all disks to our server. Once complete we analysed all of the images to determine the RAID settings and configuration. We found two different RAID’s with completely separate configurations. We used the settings to create virtual copies of the RAIDs and were able to carry out a successful recovery from both RAID Volumes.

The client was gobsmacked by the outcome. You can see his comment below:

DataQuest are amazing, we sent 7 HDD’s in a unknown raid configuration and with a failed hard drive, they managed to recover all the information we needed and more! I believed it was an impossible task, but obviously these guys know their stuff and are miracle workers! I thank the team at DataQuest and would recommend them to anyone! – Matt Bayley – February 29, 2016

We had a very satisfied customer as well as very satisfied RAID recovery Engineer. Well Done Dan, give yourself a pat on the back.
