CD- or DVD-Drive Problems and Solutions

The CD or DVD drive has a single LED that indicates whether the drive is busy. It does

not have an LED that indicates whether a fault has occurred.

Tabl e 3 -9 lists some possible problems that the CD-ROM drive could encounter, as well

as some corrective actions.

Slow response time The disk drive might be full. Ideally, at least 15 percent of the disk drive

should be free for system activity. Delete unnecessary files, or move files

to another disk drive.

You might need to defragment the disk drive.

Mirror regeneration might be occurring. Try to schedule mirror

regeneration for a time when the system is not heavily used. However, if

the disk contains business-critical data, you should regenerate the mirrors

as soon as possible.

The disk drive might be reading a compressed file. In the future, avoid

compressing files that are heavily used.

Many read or write operations might be queued to the disk drive. If the

Express5800/320Ma Software Availability Manager indicates an unusually

high number of disk requests outstanding, you should examine how your

applications are using the disks. For more information about the

Express5800/320Ma Software Availability Manager, see the

Express5800/320Ma Software Availability Manager User’s Guide.

Errors might be occurring on the drive. Check the system event log.
