13.1 Data In Commands

These commands are:

Device Configuration Identify

Identify Device

Read Buffer

Read Log Ext

Read Multiple

Read Multiple Ext

Read Sector(s)

Read Sector(s) Ext

S.M.A.R.T. Read Attribute Values

S.M.A.R.T. Read Attribute Thresholds

S.M.A.R.T. Read log sector

Execution includes the transfer of one or more 512 byte (>512 bytes on Read Long) sectors of data from the device to the host.

Note that the status data for a sector of data is available in the Status Register before the sector is transferred to the host.

If the device detects an invalid parameter, then it will abort the command by setting BSY=0, ERR=1, ABT=1.

If an error occurs, the device will set BSY=0, ERR=1, and DRQ=1. The device will then store the error status in the Error Register. The registers will contain the location of the sector in error. The erroneous location will be reported with CHS mode or LBA mode, the mode is decided by mode select bit (bit 6) of Device register on issuing the command.

13.2 Data Out Commands

These commands are:

Device Configuration Set

Format Track

Security Disable Password

Security Erase Unit

Security Set Password

Security Unlock

Set Max Set Password

Set Max Unlock

S.M.A.R.T Write Log Sector

Write Buffer

Write Log Ext

Write Multiple

Write Multiple Ext

Write Sector(s)

Write Sector(s) Ext

Execution includes the transfer of one or more 512 byte (>512 bytes on Write Long) sectors of data from the host to the device.

If the device detects an invalid parameter, then it will abort the command by setting BSY=0, ERR=1, ABT=1.

If an uncorrectable error occurs, the device will set BSY=0 and ERR=1, store the error status in the Error Register. The registers will contain the location of the sector in error. The errored location will be reported with CHS mode or LBA mode. The mode is decided by mode select bit (bit 6) of Device register on issuing the command.
