IF you have the time. Stick in it a freezer bag with some desiccant gel packs (more the better) for 48 hours. THEN throw the whole shebang in the freezer. Shouldnt be much moisture in the bag then. ;)

I personally never do it as Im impatient, but if Ben is that worried about condensation...etc etc. Then again I also connect it exteranlly in USB dock so that IF it does go pooof, it doesnt take the rig with it, only the USB add on card in the older testbed (ie rig that if it goes poof... it donna matter).

Either way, once you do it, the drive is toast. This really is the act of last resort....though maybe the hit it with a soft mallet trick should be consider the ABSOLUTE action of last resort. :P

I was thinking for those who are scared of the condensation element.... leave any sata, power, or usb cables attached and seal the bag (or whatever you're using) with the cables left simply hanging out. Then once it's out of the freezer just don't open the packaging. Maybe even set the drive in a container filled with ice cubes to keep it cool while trying to recover the data.

HDs already have dessicant in them. I wouldn't worry about condensation at all.

I've only done it once but it did work....

I've done another 'trick' that I learned from an old hardware guru when I worked at the comp shop in my teen years that may help explain this;

Much like the bad nvidia chipsets soldering ROHS fiasco of about 4 (?) years ago, sometimes it seems it could be a heat/solder/pcb issue. We would take a can of compressed air, do the upsidedown method to chill the main chipset on the HDD off and get data off that way. This probably worked (guestimate) 70-80% of the time on freshly dead drives to get some or all of the data off. It could also explain the freezer method to some extent.

As to the condensation problem mentioned, arnt drives airtight/vacuumed? I always assumed they would be under a vacuum to help reduce friction/drag and spinup times.

Edit: Forgot my disclaimer;

I actually have deep freeze spray for just that reason. It has a place in science , and anyone worth their weight and owning a rework station (I have two , both Hakko) knows to keep a can of that as it can help you sort out where the problem is.

Actually I don't think they are. They have air holes on them in order to equalize the air pressure inside/outside. Otherwise basic stuff like changing elevations would have a dramatic effect on drive functionality.

Hard drives definitely aren't air tight. The label of every HDD states in one way or another not to cover any holes in its chassis.

You're right, I remember this label now. Guess Ive just been using SSD's too long.

I still stand by my Freeze the Chip methodology of fixing dead/dying hdd's tho!

If all other available options have been expended and the drive is otherwise useless, I don't see the harm in trying. There's nothing to lose at that point.

However if the data was valuable enough to justify professional recovery fees, I would bypass this and any method of recovery that had the potential to make the issue worse.

I guess it may also have the *potential* -- although unlikely -- to void a warranty?

I believe it is professionally ethical to include relevant disclaimers, but there's no need to remove the video.
