More Troubleshooting For Drives
This section provides more information on how to solve problems with your drives or
accessory boards.
WARNING Be sure to disconnect the power cord and any telecommunication cables from
your computer before you remove the cover to check the cable connections or
jumper settings.
To avoid electric shock and harm to your eyes by laser light, do not open the
CD-ROM drive enclosure. The CD-ROM drive should be serviced by service
personnel only. Refer to the label on the CD-ROM for power requirements and
wavelength. This workstation is a class 1 laser product. Do not attempt to
make any adjustment to the laser unit.
If The Hard Disk Has A Problem
1. If you receive a S.M.A.R.T. alert during Power-On-Self-Test, there could be a
potential problem with the hard disk drive. Carry out an immediate data backup,
then contact HP Support.
2. Check that the disk power and data cables are correctly connected (refer to Chapter
6 for information about cables and connectors).
3. Check that booting from the hard drive has not been disabled in the Boot menu of
the Setup program, accessed by pressing F2 at startup.
4. Check that the hard disk drive has been detected (refer to the Hard Disk Drives
submenu in the Boot menu in the Setup program, accessed by pressing F2 at
startup).
5. Run ScanDisk and Disk Defragmenter to see if they detect a problem with the hard
disk drive. To access these utilities, select Programs > Accessories >System Tools from
the Start menu.
6. Run IDE or SCSI tests from the Advanced System Test option from HP e-DiagTools
(described on page 182).
If The Hard Disk Activity Light Does Not Work
If the hard disk activity light does not flicker when the workstation is accessing the hard
disk drive:
1. Check that the control panel connector is firmly attached to the system board.
2. Check that the disk power and data cables are correctly connected.
CD-ROM, DVD or CD-RW Drive Does Not Work
1. Check that a CD (or DVD) is inserted in the drive.
2. Check that all cables (data, power and audio) have been properly connected both to
the drive and to the system board.
