Surely they are spec'd for normal running temperature, 45 deg C not -21
deg C? I'm a great believer in Physics though.

I'd agree a serious chill ought to make every thing looser. It depends
want the problem is though.
Well they were old 2G SCSIs that had sat in attic. They wouldn't spin
Also a company assembling PCs and formatting drives circa 1992 in a very
chilly warehouse found that there was a lot of bad blocks, to extent of
boot crashing. When the PCs where left on for 15 min for drive to warm
to normal temperature, and formatted there was no problem. About 40 PCs
I'd guess modern glass platter drives are different. I just replaced
the 5 year old 40G drive in my laptop with a 120G. I have 360M, 13G,
2x 30G and other 40G drive knocking about. With a bit of a search you
will find a matching drive. I used a desktop PC with both drives
plugged in on adaptors and partition Magic to copy. I'd only use
Partition Magic on a 100% OK drive.
The little torx screw drivers are same size and sold cheaply for DIY
phone LCD replacement. Usually the PCB unclips simply when the screws
removed. Much easier than fixing broken packet dependencies :)
