Removable drives (hard drive, CD-ROM drive, DVD-ROM drive,
diskette drive, SuperDisk LS-120) are fragile computer
components that must be handled with care.
Back up the hard drive before removing it. Failure to back up
the hard drive can result in loss of information stored on the
drive if it is handled improperly.
If there is a diskette, CD, or DVD-ROM in a drive, remove it
prior to removing the drive from the computer.
Do not remove a CD-ROM drive or DVD-ROM drive while
the drive drawer is open. Before removing the drive, ensure
that the drive drawer in fully closed.
Turn off the computer before removing or inserting a hard
drive.
If you are using Windows 95, Windows 98, or Windows NT
4.0 pre-installed by Compaq, it is not necessary to turn off the
computer before inserting or removing the DVD-ROM, CD-
ROM, or diskette disk drive from the MultiBay.
If you installed Windows 95, Windows 98, or Windows NT
4.0 on your own, additional software is required to swap these
MultiBay devices while the computer is tuned on.
NOTE: The computer must be turned off to insert or remove
the SuperDisk LS-120.
