Works for me
Authored by: dcclark on Nov 03, '06 07:43:59AM

When my powerbook HD was dying last summer (the temps got very very high, and something expanded too much and started grinding inside the drive), I actually stuck the powerbook in our fridge for a while and then operated it from there. It worked well enough to do a quick backup, but it *only* postpones the death of the drive. If it's gonna die, it's gonna die.

Be very careful about doing this and then taking the laptop out of the fridge/freezer -- the author mentions putting his in a bag, which is a good idea but might not be enough. You really don't want liquid condensing inside your laptop!

I guess I need to post more hints

I've known about this for years.

Biggest use I saw was a batch of bad Portege HDDs about 5-6 years ago. However, they only worked when frozen. Put the drive in the freezer for an hour or so (small item, so cold soak does NOT take 8 hours) and then got about 20 minutes of good runtime before it warmed up enough to fail again. Took about 5 cycles to get all the data pulled from the drive.

Personally, I'd get a longer drive and power cable and just run the drive from INSIDE the freezer. Avoids the codensation issues, and once you remove it, its going straight to the trash, anyway.


Conjecture is that it has something to do with the bearings. This /seems/ to be so, as the drive sounds like its running slower when it starts to fail, then will not spin reliably at all. Not, of course, sure what's actually happening. Coule be motor, voice coil, control circuits, resistors, or anything else, also.

Bag alone helps little, one needs silica gel

A bag alone will not prevent condensation or ice formation since the air in the bag will have maybe 50% humidity at room temperature, which in the fridge/freezer when cooled down will reach 100% pretty quickly, pretty much what you have in the fridge/freezer already.

It will prevent condensation dropping from above on the drive, though.

To really prevent condensation, you need a sealed back plus enough silica gel (or similar material), let the silica gel adsorb the humidity for mabye an hour before you put everything in the fridge/freezer.

Hard drives are sealed anyway, so I doubt any of this is a problem.

Hard drives are not completely sealed.
