Diagnostic Tools 4-39 SCSI Error Codes This section includes the error codes for the following SCSI devices: s Hard drives s CD-ROM drives s 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 Table 4-26, Table 4-27, and Table 4-28. s AA (Table 4-26) identifies the drive type being tested. s BB (Table 4-27) identifies the type of test. s 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: Y Table 4-26 to identify the meaning of the first two numbers, 65. This indicates a hard drive problem. Y Table 4-27 to identify the meaning of the second two numbers, 23. This refers to a random read. Y Table 4-28 to identify the meaning of 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. Error Code 65XX-XX 66XX-XX 67XX-XX Table 4-26 SCSI Device Names Device Hard Drive CD-ROM Drive Tape Drive
