One common piece of advice is to put your drive in the freezer.
Indeed, you used to be able to fix early drives where the spindle had
been misaligned by suddenly lowering their temperature. This is because
it would shrink the drive’s components by an extremely small degree and
it could move everything back into place. New drives are far more
specific in their design and now shrinking of the components usually
make things even worse. On top of this, putting the drive in the freezer
can cause condensation. When the drive dries out it can cause rusting
and damage to the electronics, which is definitely a situation you don’t
want to find yourself in.
Another method that people might suggest is hitting your drive or
dropping it from a height. Again, with older drives a sudden impact
could knock the drive head back into place if it had become misaligned.
It certainly wasn’t an ideal or reliable fix and that’s even truer with
modern drives. If the drive head has become stuck to the platter,
knocking it in even further can cause damage that will be impossible to
fix. This is because your data will be physically worn off from the
platter.
Some adventurous people may attempt to replace the electronics board on
the hard drive. This is unadvisable because these boards are designed
with your specific drive in mind and contain information that can’t be
found on another board. Applying the wrong component to your drive can
cause damage to the platters. Also, the fault may not lie with the
electronics board and you should never attempt to fix the problem if
you’re not fully confident in what it is or how to sort it.
The fact of the matter is that you shouldn’t try freezing your drive,
dropping it or replacing the electronics in an attempt to fix the
problem. You might feel like throwing it across the room in frustration,
but it’s not going to help anything. In fact, it’ll likely just make
things worse. Hard drives are very precise pieces of kit and as such
they need to be treated with care. You need to send your drive to a data
recovery expect if you want the best chance of getting your data back.
