Epson 10020 - Manual (Page 52)

If you have the Apex 100\20, follow these additional
precautions to protect your hard disk drive and its data:
Never turn off the computer when the hard disk drive light
is on. This light indicates that the computer is copying data
to or from the hard disk. If you interrupt this process, you
can lose data.
Never attempt to open the hard disk drive. The disk itself
is enclosed in a sealed container to protect it from dust.
If you need to move the computer, be sure to run the
HDSIT program before you turn it off. See “Preparing the
Hard Disk for Moving,” later in this chapter.
Inserting and Removing Diskettes
To insert a diskette into the drive, hold it with the label facing up
and the read/write slot leading into the drive, as shown below.
Slide the diskette into the slot until it is in all the way. Then
turn the latch down to lock it in a vertical position. This keeps
the diskette in place and enables the read/write heads in the
disk drive to access the diskette.
