Topic Wiki

Ok so my rule of determining the level of difficulty in data recovery is really 2 questions.
#1 -  is it making any noise
#2 -  is it detected in the bios if you connect it directly to the mobo

If the answer to #1 is yes - then if you want any hopes of recovering the data do not attempt to continue powering it on. It can be making noise because the heads are broken or bent and if that's the case you will scrape the platters and kill the drive beyond any hope of recovery. (data recovery isn't like the way they show it in the movies you cannot actually remove a platter and recover any data off it) And please do not attempt the Freezer Trick - it doesn't work on current drives anymore and actually introduces condensation in the drive that can kill the platters.
If its detected in the bios we can try a couple of things - and i can usually recover the data for about $250 - $799 - over 50% of the time its about $300.

todays tip - guys an external hard drive is not! a backup if its the only place you have the files! I get this all the time - my backup died, ok so use the original files, this is the original - then it isn't a backup!! And btw interesting piece of info -external hard drives are way inferior to internal drives. Basically when the manufacturers test the drives before they go I to production they use the best ones as internal drives - because they figure that's where you put the important data. The ones that aren't as good are sold as external drives.

so external drives are made because of "mistakes"?

Not really mistakes. Basically when har drive were 40gb - 80gb etc the drives were prob 95% perfect - no bad sectors on the drive. New drives today I would say at least 35% have bad sectors straight out of the box. Now the truth is that hard drives are prepared for bad sectors and they have built in error correction - (this doesnt actually repair the sector, but it marks it as bad so it shouldn't be used and it has a special list telling the drives where the bad sectors are and it will avoid it) this doesnt always work right because if it gets bad sectors where the mft is (mft is kind of an index telling the drive where all the data is and what sectors have data) it wont be able to read the drive (there is a backup mft but they can both fail and ive seen this happen many times).
External drives are usually the drives with more errors or the ones that werent built perfectly and they had to make some changes to correct them.

on what you said

And please do not attempt the Freezer Trick - it doesn't work on current drives anymore and actuall introduces condensation in the drive that can kill the platters.

So here is the deal with the freezer trick
THE PROBLEM  - older hard drives especially pre 2000 used a special lubricant to help the read/write heads move smoothly across the drive. Over time (and sometimes due to heat or other conditions) the lubricant would break down, lose some of its smoothness and sometimes become sticky. What followed was when you would stop using the machine or power it down the read/write heads would get stuck in the broken down lubricant and stop moving when you turn it back on.

THE SOLUTION - People did one of two things to try to recover the data - Both of them CAN ABSOLUTELY damage the drive but it did work part of the time. 1) giving the drive a little knock on the side - WHEN IT'S OFF - sometimes worked. Remember this can also damage the read/write heads especially if they are stuck to the drive and can also cause platter damage if the heads breaks off or gets stuck to the platter and then you power it on. 2) Putting the drive in the freezer sometimes expanded the chip (cold expands) and helped the heads move off the platters so you can recover the data quickly. This can also damage the platters as well by bringing in condesation into the drive and when you take it out of the cold the condesation can move over the platter and the heads will destroy it.

THE FIX - The hard drive Manufacturers solved this issue by introducing a little ramp that the heads park on when they power down as a result 99% of the time the freezer trick will do more harm than good.

Sometimes the freezer trick will still work because changing the temperature in the drive can sometimes alter the situation and help the drive work again - however I would say even in that case dont put the drive in the freezer rather get a really cold surface - (You can get a usb powered cooler) and place the drive on the cool surface to achieve the same temperature withought risking additional damage to the drive.
