Using A Hard Disk; Backing Up The Hard Disk - Epson ActionNote 4SLC/25 User Manual

When you swap diskettes this way, it is a good idea to
write-protect the original diskette so you don't accidentally
write over it. (See "Write-protecting Diskettes" earlier in this
chapter for more information.)

Using Hard Disk
The hard disk installed in the ActionNote has been prepared
for use at the factory. It also may have MS-DOS and Windows
installed. If you plan to use MS-DOS or Windows, you can
install your application programs and begin work. See the
documentation that came with your programs for instructions.
Follow these precautions to protect your hard disk from
damage and to avoid losing data:
Never turn off or reset 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.
After turning the power off, wait 20 seconds before moving
the computer. This allows the disks in the drive to stop
spinning and the hard disk read/write heads to lock in
place so you do not damage the drive.

Backing Up the Hard Disk

Although the hard disk is very reliable, be sure to back up your
files onto diskettes in case you lose some data accidentally.
Make copies of all your system and application program
diskettes before copying the programs to the hard disk. See
your operating system manual for instructions.
