Hard Disk Problems
This section provides some guidance on investigating problems
with the hard disk. You should make sure when trying to solve hard
disk problems that you do not erase important files unnecessarily.
Note:
Make regular backups of files on the hard disk and keep backup disks of
applications.
The computer appears to be operating slower than normal
and with prolonged periods of disk access.
• The hard disk may be nearly full or have errors. Check using the
SCANDISK utility (see the Windows Help file). If full, try
emptying the recycle bin or deleting any unnecessary files to free
up some space on the hard disk (e.g. old files or files with .BAK,
.CHK or .TMP extensions).
• The files on the disk may have become fragmented. Check by
using the DEFRAG utility (see the Windows Help file).
You cannot boot up using the hard disk.
• Does the hard disk LED flash during start-up? Run the FDISK
command (see the operating system manual) and check for an
active partition. Note: Hard disk drives bigger than 2.0GB may
have two partitions.
Beware:
FDISK can destroy the information held on your hard disk if you re-partition.
• Check to see whether the BIOS System Configuration screen
(displayed during start-up) reports a hard disk is present.
Note:
Some viruses can change the BIOS configuration so check by running a virus
checking program.
