where it will be used, allow the disk drive to gradually reach the temperature of the room. By
allowing the disk drive time to aacclimate, data loss or permanent damage to the disk drive
can be avoided. The proper time is at least one hour for each 10°C (18°F) of difference
between the storage environment and the operating environment.
