Hard drive problems

The directory structure is bad,
or there is a problem with a file.
Improper cable connection
Improperly seated hard drive
The system might not have
automatically recognized a
newly installed device.
Drive responds slowly
immediately after power-up.
System is trying to start from a
nonbootable diskette.
System is trying to start from a
damaged hard drive.
System files missing or not
properly installed.
Hard drive boot disabled in
Computer Setup.
Hard drive is damaged.
Solution
Locate and block the usage of bad sectors. If necessary,
reformat the hard disk.
If the drive is detected by the BIOS, run DPS Self-test.
1. Right-click Start, select Explore, and select a drive.
2. Select File>Properties>Tools.
3. Under Error-checking, select Check Now.
On workstations with discreet data and power cables,
ensure that the data and power cables are securely
connected to the hard drive. (See the Hard drive section of
this guide for connection details.)
On systems with blind-mate drive connections, check for
connector damage on the drive and in the chassis.
Reseat the hard drive and its carrier in the chassis to
ensure a proper connection. (See the Hard drive section of
this guide for connection details.)
1. Run the Computer Setup (F10) Utility.
2. If the system does not recognize the new device,
verify that the device is listed in the Computer Setup
(F10) Utility.
If it is listed, the probable cause is a driver problem. If
it is not listed, the probable cause is a hardware
problem.
3. If this drive is newly installed, enter Setup and try
adding a POST delay under Advanced>Power-On.
Run the Computer Setup (F10) utility, and increase the
POST Delay in Advanced>Power-On Options.
Remove the diskette from the drive.
1. Insert a bootable diskette into the drive and restart the
workstation.
2. If the hard drive is still inaccessible and MBR Security
is enabled, try restoring the previously saved
MBR image by entering Setup and selecting
Security>Restore Master Boot Record.
1. Insert a bootable system diskette and restart.
2. Verify that the hard drive is partitioned and formatted.
3. Install the system files for the appropriate operating
system, if necessary.
Run the Computer Setup (F10) Utility and enable the hard
drive entry in the Storage>Boot Order list.
Replace the hard drive.
