Re: Freezing HDD

[Clark Martin]

I’ve got a large collection of drive magnets and disk platters from the many 
drives I have disassembled over the years.

Re: Freezing HDD

There is a much less risky step you can try first.  Hold the drive and give it 
a twist around the disk spin axis, as hard as you can.  This can often unstick 
the heads.  If that doesn’t do it then you can try opening it up.

That’s true, cool stuff to salvage. Those magnets are strong, I’ve been pinched 
where I was bleeding by not being careful with those magnets.

I had success once, and failure twice, freezing a bad HD.

I also had a HD that overheated very quickly, I was able to run an air hose 
from a compressor into my house, and start with ‘cold’ (not frozen) HD with air 
blasting over it. I was able to copy all the data off the HD before it died 
from heat, and it would always quit working in only 10 minutes without the air 
cooling blasting over it.

Failing HDs need to be copied ASAP and trashed, they can’t be saved, only the 
data on them can be saved.

Re: Freezing HDD

[Len Gerstel]

It does work OCCASIONALLY for a limited subset of problems. Note that it is a 
last ditch effort. Before you start, have everything you need to back up the 
hard drive should it work and back it up immediately.

Also, there is always the possibility of a circuit board failure on the drive 
and I have known people to buy a working HD off ebay of the same model and swap 
the board. 

Both of these assume a hardware failure, not software.

HTH,
Len

Re: Freezing HDD

[Google]

Do a search for “stiction” and you’ll likely find that some folks will have 
declared that freezing their drive(s) caused the drives to spin up again long 
enough to retrieve the data on them. If all else fails, it’s worth a try. It 
worked once for me, FWIW.

Freezing HDD

The hard drive on my PM 5300 looks like it has failed. Is there any truth 
that freezing the drive might restore it or is it one of those myths?
