Troubleshooting the Hard-Disk Drive
During POST, the computer checks the hard-disk drive,
comparing its characteristics with the system configura-
tion information. (The hard-disk drive/CD-ROM drive
access indicator blinks as the computer performs this
check.) If a failure occurs with the drive, make a copy of
the Diagnostics Checklist found in Chapter 5 and fill it
out as you complete the following procedure.
NOTE: If you have another hard-disk drive that you know
is in good condition, install it in your computer before
you begin this procedure and perform the operation that
caused you to suspect a hard-disk drive failure. If there is
no evidence of a drive failure with the second drive
installed, the first drive is probably defective. If the sec-
ond drive fails, reinstall the first drive and start the
following procedure.
1. Reboot the computer. Does the drive access indica-
tor blink during the boot routine, and does the drive
boot the operating system?
Yes. If a message appears on the display, see
Table 3-2 for an explanation of the message and pos-
sible corrective actions. Then go to step 6.
No. Continue to step 2.
2. Insert your operating system diskette into drive
A, and reboot the computer.
3. Check drive C in the Windows 95 Explorer. Are
the root directory contents for drive C displayed?
Yes. Go to step 5.
No. Continue to step 4.
4. If your hard-disk drive has more than one logical
drive, check drive D. Are the root directory con-
tents for drive D displayed?
Yes. Continue to step 5.
No. You may have a corrupted boot sector or file
allocation table (FAT) on drive C. Go to step 8.
5. Rename your autoexec.bat and config.sys files,
remove the operating system diskette from drive A,
and reboot the computer. Does the operating system
load now?
Yes. You have an error in your autoexec.bat or con-
fig.sys file. Use a text editor to examine the contents
of these files and locate the error. For information on
the correct syntax for commands in these files, see
the documentation that came with your operating
system.
No. Continue to step 6.
6. Insert your diagnostics diskette into drive A, and
reboot the computer. Then run the Hard-Disk
Drive test group. Does your drive pass all the
tests?
Yes. Continue to step 7.
No. Go to step 8.
7. Replace your diagnostics diskette with the operat-
ing system diskette, and reboot the computer.
Does the operating system load now?
Yes. The hard-disk drive may contain a corrupted
operating system or it may have bad sectors. Re-
install the operating system as described in the
documentation that accompanied your operating sys-
tem. If reinstalling the operating system does not
correct the problem, continue to step 8.
No. Continue to step 8.
8. Call Dell for technical assistance.
