Solution
1. Run Computer Setup.
2. If the system still does not
recognize the new device,
check to see if the device is
listed within Computer Setup. 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 is a newly installed drive,
enter Setup and try adding a
POST delay under Advanced
> Power-On.
If the drive is a secondary drive that
has just been installed on the same
cable as the primary drive, verify
that the jumpers for both drives are
set correctly.
Run Computer Setup and enable the
Primary and Secondary IDE (ATA)
controllers in Storage > Storage
Options.
Run Computer Setup and increase
the POST Delay in Advanced >
Power-On Options.
Remove the media from the drive.
1. Insert a bootable diskette into
the diskette drive and restart the
computer.
2. Check hard drive format using
fdisk:
If NTFS formatting, use a third
party reader to evaluate the
drive.
If FAT32 formatting, the hard
drive cannot be accessed.
Replace the MBR image.
3. 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.
