SCSI Error Codes

This section includes the error codes for the following SCSI devices:
Hard drives
CD-ROM and DVD-ROM drives
Tape drives
The SCSI error codes are written in the format AABB-CC and can be determined by looking up
the respective parts of the code in the three corresponding tables numbered 4-25, 4-26, and 4-27.
AA (Table 4-25) identifies the drive type being tested.
BB (Table 4-26) identifies the type of test.
CC (Table 4-27) identifies the exact error received.
For example, if you received a diagnostic error code of 6523-05, you would look at:
Table 4-25 to identify the meaning of the first two numbers, 65. This indicates a hard
drive problem.
Table 4-26 to identify the meaning of the second two numbers, 23. This refers to a
random read.
Table 4-27 to identify the last two numbers, 05. This indicates a seek failure.
When you combine this information, you know that the diagnostics program was testing the
random-read functioning of the hard drive and received a seek failure. The device is faulty and
must be replaced.
