ATA COMMAND BLOCK AND SET DESCRIPTION

SSD-PXXX(I)-3521 DATA SHEET

Read Verify Sector(s) — 40h, 41h

The Read Verify Sector(s) command operates similarly to the Read Sector(s) command, with the exception that is does not set the DRQ bit and does not transfer data to the host. When the requested sectors are verified, the onboard controller clears the BSY bit and issues an interrupt.
