    DISK DRIVE OPERATION SMART capability The following describes the definition for the SMART capability bits. If the value of all of these bits is equal to zero, then this device does not implement automatic saving of SMART data. • Bit 0 (power mode SMART data saving capability bit) – If the value of this bit equals one, the device shall save its SMART data prior to going into a power saving mode (Idle, Standby, or Sleep) or immediately upon return to Active or Idle mode from a Standby mode.

  • Page 84: Standby (96H, E2H)

    DISK DRIVE OPERATION 6.4.25 Standby (96h, E2h) This command causes the drive to enter Standby Mode. See 6.6.3 for the protocol. The drive may return the interrupt before the transition to Standby Mode is completed. If the drive is already spun down, the spin down sequence is not executed. 6.4.26 Standby Immediate (94h, E0h) This command causes the drive to enter Standby Mode.

  • Page 85: Write Multiple Command (C5H)

    DISK DRIVE OPERATION 6.4.30 Write Multiple Command (C5h) This command is similar to the Write Sectors command. The drive sets BSY within 400 nsec of accepting the command, and interrupts are not presented on each sector but on the transfer of a block which contains the number of sectors defined by Set Multiple.
  • Page 86 DISK DRIVE OPERATION If the ID is read correctly, the data loaded in the buffer is written to the data field of the sector, followed by the ECC bytes. Upon command completion, the Command Block registers contain the cylinder, head, and sector number of the last sector written in CHS mode or the logical block address in LBA mode.
