The drives support the following Maxtor specific commands:
• READ DEFECT LIST
• READ CONFIGURATION
• SET CONFIGURATION
4'#& &'('%6 .+56
The READ DEFECT LIST command enables the host to retrieve the drive’s defect
list. Prior to issuing this command the host should issue the READ DEFECT LIST
LENGTH command. This command will not transfer any data. It instead, stores the
length in sectors of the defect list in the Sector Count register (1F2), and the Sector
Number register (1F3), with the Sector Count register containing the LSB of the 2-
byte value (see Table 6-3). The defect list length is a fixed value for each Maxtor
product and can be calculated as follows:
length in sectors = (((maximum number of defects) * 8 + 4) + 511)/512
At the completion of the command, the task file registers 1F2 – 1F6 will contain bytes
necessary to execute the READ DEFECT LIST command, and the host will only
need to write the extended command code (F0h) to the Command register (1F7) to
proceed with the READ DEFECT LIST command execution.
