2.6 Hard Disk Drive (HDD) Troubleshooting
To determine if the hard disk drive is functioning properly, do the procedures below starting
with Procedure 1. Continue with the other procedures as instructed.
Procedure 1: Partition Check
Procedure 2: Message Check
Procedure 3: Format Check
Procedure 4: Diagnostic Test Program Execution Check
NOTES: 1. The contents of the hard disk will be erased when the HDD troubleshooting
procedures are executed. Transfer the contents of the hard disk to floppy
disk or other device. If the customer has not or cannot perform the backup,
create backup disks as described below.
2. Check to see if the Microsoft Create System Disks Tools (MSCSD.EXE) still
exists in the System Tools Folder. (This tool can be used only once.) If it
exists, use it to back up the preinstalled software, then use the Backup utility
in the System Tools folder to back up the entire disk, including the user's
files.
Refer to the operating system instructions.
Procedure 1 Partition Check
Insert the Toshiba MS-DOS system disk, turn the computer on, then perform the following
checks:
Check 1 Type C: and press Enter. If you cannot change to drive C, go to Check 2. If you
can, go to Procedure 2.
Check 2 Type FDISK and press Enter. Choose Display Partition Information from the
FDISK menu. If drive C is listed, go to Check 3. If not, return to the FDISK
menu and choose the option to create a DOS partition on drive C. Recheck the
system. If the problem still exists, go to Procedure 2.
Check 3 If drive C is listed as active in the FDISK menu, go to Check 4. If not, return to
the FDISK menu and choose the option to set the active partition for drive C.
Recheck the system. If the problem still exists, go to Procedure 2.
Check 4 Remove the system disk from the FDD and cold-boot the computer. If the
problem still exists, go to Procedure 2. Otherwise, the HDD is operating normally.
