I have to comment--only do this if the data on the disk is NOT very
important to you, if you must do it. If it _is_ important, give the
disk to someone like Gillware (gillware.com) for professional recovery.
They have the tools, up to and including a clean room for disassembled
recovery.
The more you work on a disk with damaged hardware, the greater the
probability that you'll exacerbate the damage, often to the point that
even recovery services won't work.
Now, if there's no hardware damage to the disk--it's just logical
corruption--you stand a far better chance of doing your own recovery,
although I urge the use of a write blocker. But in this case, you
don't need to consider freezing the disk (or some of the other "recovery
techniques" I've heard over the years--dropping the disk a few inches
on a hard surface, putting it in the oven, etc.)
Frankly, while some of these came from real-world instances--for instance,
the bit about dropping the disk worked on some drives, long ago, because
they used the wrong lubricant and there was a "stiction" problem--most are
humbug. Think long and hard about how important that data really is, and
do some serious googling before trying any of these.
