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 4-26, 4-27, and 4-28.

■AA (Table 4-26) identifies the drive type being tested.

■BB (Table 4-27) identifies the type of test.

■CC (Table 4-28) identifies the exact error received.

For example, if you received a diagnostic error code of 6523-05, you would look at Table 4-26 to identify the meaning of the first two numbers, 65. This indicates a hard drive problem. The second set of two numbers, 23, refers to a random read, as shown in Table 4-27. The last two numbers, 05, indicate a seek failure, as listed in Table 4-28. 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.
