Write Log Ext (3Fh)

Table 117: Write Log Ext command

Output parameters to the device

Sector Count Current

The number of sectors to be written to the specified log low order, bit (7:0).

Sector Count Previous

The number of sectors to be written to the specified log high orders, bits (15:8). If the

number of sectors is greater than the number indicated in the Log directory, which is avail-

able in Log number zero, the device shall return command aborted. The log transferred to

the device shall be stored by the device starting at the first sector in the specified log.

Sector Number Current

The log to be written as described in Figure 51 Log address definition. If the host

attempts to write to a read only log address, the device shall return command aborted.

Cylinder Low Current

The first sector of the log to be written low order, bits (7-0)

LBA Low Previous

The first sector of the log to be written high order, buts (15:8)

If the feature set associated with the log specified in the Sector Number register is not supported or enabled, or if

the values in the Sector Count, Sector Number or Cylinder Low registers are invalid, the device shall return com-

mand aborted. If the host attempts to write to a read only log address, the device shall return command aborted.
