External Hadr Drive problem

So the situation is as follows:

I have an external Hard Drive. The one, which is powered only from USB. It's difficult to tell the model, as it was bought from the Internet as Western Digital 500GB, but when delivered it turned out to be fake ( well it was suprisingly cheap, and should've read the description more carefully). However it worked fine, so it wasn't really a problem. Two weeks ago it suffered an airplane transportation ( i say suffered, because it was transported in the luggage , somewhere in the bottom of the bag), and after that it doesn't mount in to OS.
When plugged in,  it starts working, so the power is supplied, but the OS doesn't react. Tried using different cords, the effect is identical. Also tried on Windows Vista, and then tried manually mounting the drive on PC-BSD OS. Both systems couldn't detect it. Other drives mount normally.

I suppose, that it's not really possible to make it work normally.  ???
Are there may be ways to, at least, extract the data from it ?

Re: External Hadr Drive problem

Take the drive out of the case.  Try using an ATA/SATA to USB adapter and see if you the OS sees the drive. 

If that doesn't work, it could be a number of issues with the drive itself.  If the drive is not making any unusual noises, like clicking, then it could be a firmware or ROM issue.  Otherwise, it's something mechanical or electrical.  Either way, you would need to send to a DR shop.

Re: External Hadr Drive problem

Apparently sometimes if you put the drive in an airtight bag in the freezer for a day or so that can help by contracting the internal components wiorth a try

Re: External Hadr Drive problem

That absolutely does work from time to time for mechanical problems.  I've saved at least 3 or 4 drives using that method.  It won't do anything for firmware or electrical issues.

Re: External Hadr Drive problem

I've heard this method referenced on this board and in the SANS Advisory Board list and have a question.  If putting a drive in the freezer would you want to use silica gel packs?

Re: External Hadr Drive problem

I've never used silica gel packs.  What I do is use an anti-static bag that can be sealed.  I then use a straw to remove the air from the bag as much as possible.  You only need about 5 to 10 mins in the fridge.

Re: External Hadr Drive problem

Thank you all for your response  :).
I was already going to use ATA/SATA adapter to test the drive, and then was going to put it in the freezer, but apparently he got scared of that and started working  ;D.
magic :o.

But that freezer thing is, actually, interesting. Never heard of that before. Thanks a lot!

Re: External Hadr Drive problem

I tried it some time ago as well and it worked here too - though I would recommend once it is running again to backup the files somewhere else and use the previously damaged hdd no longer.

Sorry, probably because of my bad English, you understood that I did put it in the freezer, but actually I didn't. I wanted to, but the drive started working by itself.
Still, big thanks for a great advice, it is still usefull, as I'm not sure that it won't happen again. So i think i'll follow it.  ::)
