    FORMATTED CAPACITY At the factory, the Maxtor Atlas 15K II 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.

    MB/second. It is fully compatible with Ultra2 LVD devices operating at slower transfer rates. If an Maxtor Atlas 15K II 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 228: Diffsens

    HVD devices pull DIFFSENS up to +5 volts via a resistor. The Maxtor Atlas 15K II 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.
