Protecting the Disk Drives

To protect the disk drives and data, back up the system disk periodically on diskettes. Oc-
casionally 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:
T
Always back up the data files from the hard disk.
T
Run a virus detecting program to check for possible virus infected areas on the
hard disk.
T
Use the preinstalled ScanDisk program to correct any errors found in the direc-
tory and File Allocation Table (FAT). This will also free up space from any un-
used sectors.
T
Never turn the computer off when the hard disk is being accessed.
T
Never move or raise the computer while the hard disk is being accessed, most es-
pecially don't jar the hard disk as this may cause a hard disk crash.
T
Acquire a hard disk maintenance program like DEFRAG under DOS, or Norton
Utilities SPEEDISK programs. These programs reorganize your hard disk by
eliminating fragmentation and improves the hard disk access time.
