Figure 109 Write Sector(s) Ext Command (34h)

The Write Sector(s) Ext command transfers one or more sectors from the host to the device, then the data is written to the disk media.

The sectors are transferred through the Data Register 16 bits at a time.

If an uncorrectable error occurs, the write will be terminated at the failing sector.

Output Parameters To The Device

Sector Count Current	The number of continuous sectors to be transferred low order, bits (7:0).
Sector Count Previous	The number of continuous sectors to be transferred high order bits (15:8). If zero is
LBA Low Current	specified, then 65,536 sectors will be transferred.
	LBA (7:0).
LBA Low Previous	LBA (31:24).
LBA Mid Current	LBA (15:8).
LBA Mid Previous	LBA (39:32).
LBA High Current	LBA (23:16).
LBA High Previous	LBA (47:40).
Input Parameters From The Device
LBA Low (HOB=0)	LBA (7:0) of the address of the first unrecoverable error.
LBA Low (HOB=1)	LBA (31:24) of the address of the first unrecoverable error.
LBA Mid (HOB=0)	LBA (15:8) of the address of the first unrecoverable error.
LBA Mid (HOB=1)	LBA (39:32) of the address of the first unrecoverable error.
LBA High (HOB=0)	LBA (23:16) of the address of the first unrecoverable error.
LBA High (HOB=1)	LBA (47:40) of the address of the first unrecoverable error.
