    FORMATTED CAPACITY At the factory, the Maxtor Atlas 10K V receives a low-level format that creates the actual tracks and sectors on the drive. Table 4-2 shows the capacity resulting from this process. Formatting done at the user level for operation with DOS, UNIX, or other operating systems, will result in less capacity than the physical capacity shown.

    6.12 DIAGNOSTICS The drive has extensive diagnostic capabilities, including those described below: power-on self-test, periodic self-adjustments, and host diagnostics. Maxtor uses self- diagnostic tests and sense data tracking to manage drive errors, in addition to logical block address (LBA) revectoring.

  • Page 221: Host Diagnostics

    6.12.4 Log Sense Maxtor implements multiple LOG SENSE pages which logically group together parameters related to disk and subsystem activities. Monitoring this data enables users to observe drive performance and possibly predict failures. 6.13 ERROR RECOVERY The mode pages control all error recovery.

    320 MB/second. It is fully compatible with Ultra2 LVD devices operating at slower transfer rates. If an Maxtor Atlas 10K V disk drive is installed on a bus with one or more single-ended (SE) devices, it automatically switches modes to operate in SE mode at the slower, legacy data rates.

  • Page 223: Diffsens

    HVD devices pull DIFFSENS up to +5 volts via a resistor. The Maxtor Atlas 10K V disk drive is designed with a circuit that monitors the level of DIFFSENS at power-on. The drive then enables the appropriate circuits for LVD or single-ended operation, or disables its interface completely if it detects an HVD level on DIFFSENS.

    Figure 6-1 ST and DT CLocking The Maxtor Atlas 10K V disk drive can operate at speeds up to 80 MB/sec in either ST or DT modes, depending on the capabilities of the host adapter. Transfer rates above 80 MB/sec are only supported in DT mode, as required by the SPI-3 SCSI standard.
