6-4 Preventive Maintenance
Protecting the Disk Drives
To protect the disk drives and data, back up the system disk periodically on
diskettes or the optional SuperDisk drive. Periodically use a head-cleaning
diskette in the disk drive to prolong the life of the drive and to help maintain
data integrity.
Here are some maintenance procedures to use when servicing a hard disk:
n
Always back up the data files from the hard disk.
n
Run a virus detecting program to check for possible virus infected areas
on the hard disk.
n
Use the preinstalled ScanDisk program to correct any errors found in the
directory and File Allocation Table (FAT). This also frees up space from
any unused sectors.
n
Never turn the computer off when the hard disk is being accessed.
n
Never move or raise the computer while the hard disk is being accessed.
Be especially careful not to jar the hard disk during access, this can cause
a hard disk crash.
n
Use hard disk maintenance program like DEFRAG under DOS, or
acquire Norton Utilities SPEEDISK programs. These programs
reorganize your hard disk by eliminating fragmentation and improve the
hard disk access time.
