Placing a disk drive in a refrigerator or freezer is never a good idea. Since the air inside a disk drive is “equalized” it mimics the ambient surrounding air, and hence it contains moisture that condensates or freezes on the delicate platters. Please be aware of the online remedies, many of which are very dangerous to a delicate hard disk. Also, NEVER hit or strike your disk. Most of these processes will only cause more problems to the disk and increase the cost!
