If an error message indicates a drive problem or if a drive seems to perform
incorrectly or not at all, the problem could be a faulty connection, a basic input/output
system (BIOS) problem, a conflict with other hardware, or a faulty drive. If BIOS prob-

troubleshoot drives:
1. Remove the computer cover and support beam as described in "Removing and
Replacing the Computer Cover and Support Beam" in Chapter 2.
2. Remove the interface cable and the DC power connector from the malfunction-
ing drive, and inspect them for damage.
3. Reconnect the interface and DC power connectors to the appropriate connectors
on the drive, making sure they are firmly seated.
