Preventing Damage to Removable Drives
Removable drives are fragile components that must be handled with care. To prevent damage to
the computer or a removable drive, or loss of information, observe these precautions:
Before removing or inserting a hard drive, shut down the computer. If you are unsure
whether the computer is off or in Hibernation, turn the computer on, then shut it down.
●
Before removing a diskette drive, CD-ROM drive, SuperDisk LS-120 drive, or a DVD-ROM
drive, ensure that a diskette or disc is not in the drive. Ensure that the drive tray is closed.
Before handling a drive, ensure that you are discharged of static electricity. While handling
a drive, avoid touching the connector.
●
Handle drives on surfaces that have at least one inch of shock-proof foam.●
Avoid dropping drives from any height onto any surface.●
Do not use excessive force when inserting a drive into a drive bay.●
Avoid exposing a hard drive to products that have magnetic fields such as monitors or
speakers.
●
Avoid exposing a drive to temperature extremes or to liquids.●
If a drive must be mailed, ship it in a suitable form of protective packaging. Shipping the
drive in standard packaging may not cushion it from destructive shock, vibration,
temperature, or humidity. Place a mailing label with the wording "Fragile: Handle With
Care" on the mailer.

and tray upside down. The drive is not secured to the tray and can fall out.
