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.

Broken USB Stick

USB Broken Connector Data Recovery

I had a call on Friday from a very distraught lady who had dropped her laptop with her USB stick still plugged in. Unfortunately the USB stick took the brunt of the impact and all her work was no longer accessible. She contacted us and I reassured her that although the device was broken, we have a good chance of getting the data back.

With time spent on the Broken USB Stick over the course of the day on Saturday, I was able to recover all of the data. I managed to get the data back to her on Sunday morning, so she could carry on working ready for the week ahead. I was also pleased to find out that the information on the USB stick was part of her charity work for people with special needs.

The customer was local to us in Portsmouth so I had the pleasure in handing the recovered data to her personally.

 

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!

What Is A Clean Room

Some parts of our data recovery process require us to open a hard drive for internal repairs.

John In Cleanroom

We have a walk in clean room area on site, that allows us to carry out the necessary rework. It consists of an overhead air shower unit with a sealed enclosure that cleans and circulates the air within a specified tolerance. To keep particles to a minimum we wear a gown, gloves, and face mask to prevent contamination from outside.

All hard drives are built in a clean room environment. Keeping small air particles out is crucial due the the complexity of the internal mechanism and tiny tolerance between the moving mechanical parts and internal disc surface that holds your data. When a hard drive requires any internal repair, it is critical that this work is carried out in a clean room.

See our video about why you should never open a hard drive without a cleanroom.

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.

Free 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 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.

Easter Backup Tips

Easter Backup Tips

The long weekend is only hours away, so if you’ve got a few spare minutes over Easter, why not get your data in order & sort out some backups. Save yourself the dread of losing all your documents or photos, and then sit back and eat some chocolate eggs!

Simple Start

First, when people talk about backups, they actually mean just make copies of your files. It sounds obvious, but this is often misunderstood. If you have a few really important files, you can make a backup of them my copying them somewhere else. That could be a memory stick, SD card, CD, DVD, Dropbox, whatever. The important thing is when you’ve copied the file, do not delete the original. For a backup to be useful, it must be a copy of some data.

The Plan

If you want to take things a step further, you probably want a way to automate the backup process. That way, your computer keeps track of new & updated files, and you don’t need to think too much about it.

Step 1

You ideally want to have enough space in your main computer to hold all your important data. This may mean investing in a larger hard drive or SSD, but is by far the easiest way to stay safe. Now whenever you use the computer, you always store the files on the large internal disk. This means any backups you make can simply be copies of this main disk.

To sidetrack slightly, imagine if you instead stored photos on one external disk, documents on your laptop, and movies on another disk. This would be a nightmare to keep backed up, as you would constantly need to attach and reattach different disks.

Step 2

Now all your data is stored on the main disk inside your computer, backups are simple. On a Mac, point Time Machine at your external disk. On a PC, point Windows Backup to your external disk. Both will create a copy of your main disk, and then take care of scheduling future copies to keep you up to date.

Never store files manually onto the external disk, as you will lose them if the disk fails. Now, when you make new files on your computer they will eventually get backed up to your external disk too. Just remember to either keep it plugged in, or plug it in regularly to catch up.

Step 3

Once you have a single backup sorted, you might think of a few ways you could still end up losing data. For example, if the external disk is always plugged in, any spike through the power lines could kill off both disks in one go. It does happen, even if you have a surge protector! Also, what if there was a fire or flood. Both disks side by side could get damaged. Then there is also the risk of the computer and all the surrounding equipment being stolen.

Luckily, there are also ways to protect yourself here too. A simple way would be to use another external disk to make a backup, but then unplug it and store it in a safe somewhere. It could be in a family member’s house, or at work, or anywhere really. Ideally not in the same building as the other disks, to cut down the chances of all disks being lost at once.

There is another way to avoid the worry of storing another disk outside your house. Online backup. Sometimes known as cloud backup, online backups give you storage on a server somewhere, and a small program on your computer to send the data over. We’ve heard great things about Backblaze for online backups. Their ex-Apple engineers have created a really simple service, that’s super cheap with unlimited storage.

Done

So now, with your backup disk humming away on your desk, and your files beaming over to a Backblaze server online, you can relax and stop worrying about losing all your files.

If you’re reading this too late and have already lost data, get in touch and we’ll see if there’s any way to get it back.

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…

Macbook Pro Trackpad Not Clicking

Portsmouth & Southsea Mac Support

We recently received a Macbook Pro for data recovery. When we removed the broken hard drive and installed a new one for the customer, we noticed that the trackpad was not working correctly and would not click when pressed. We dismantled the Mac again and removed the battery which was underneath the trackpad. When the battery was removed we found that the underside of battery had blown and was pushing against the trackpad. We installed a new battery, recovered the customers data and now the mac is working fine.
