ATA COMMAND BLOCK AND SET DESCRIPTION

SSD-CXXX(I)-3600 DATA SHEET

Read Sector — 20h, 21h

The Read Sector command allows the host to read sectors 1 to 256 as specified in the Sector Count register. If the sector count is set to 0h, all 256 sectors of data are made available. When the command code is issued and the first sector of data has been transferred to the buffer, the DRQ bit is set. The Read Sector command is terminated by writing the cylinder, head, and sector number of the last sector read in the task file. On error, the read operation is aborted in the errant sector.
