Epson LT - 286e - Manual (Page 61)

Never remove the hard disk unit when the computer’s
power is on.
Never attempt to open the hard disk unit. The disk itself is
enclosed in an airtight container to protect it from dust.
Keep the AC adapter at least six inches away from your
computer and disks.
Protecting the Data on Your Hard Disk
Although the hard disk is very reliable, you must back up your
hard disk files onto diskettes in case you lose some data
accidentally.
Make backup copies of all your system and application program
diskettes before copying the program files to the hard disk. Copy
your data files frequently to keep your backup diskettes up to
date.
Use the Epson MENU utility or the MS-DOS BACKUP
command to back up your hard disk files. Use the MENU utility
or the MS-DOS DISKCOPY command to make copies of your
system and program diskettes. For instructions on using these
backup utilities, see Chapter 3 or your MS-DOS manuals.
Improving Hard Disk Performance
MS-DOS includes a program called FASTOPEN, and a device
driver called SMARTDRV.SYS, that can improve your hard
disk’s performance. For information about using these features,
see your MS-DOS Reference Manual.
