SCSI Error Codes
This section includes the error codes for the following SCSI devices:
■
Hard drives
■
CD-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 Table 4-25, Table 4-26, and Table 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 for
example, indicates a hard drive problem.
■
Table 4-26 to identify the meaning of the second two numbers. 23 for
example, refers to a random read.
■
Table 4-27 to identify the meaning of the last two numbers. 05 for
example, 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.
