The READ DRIVE STATUS command requests the drive to report its specific drive status to the
initiator.
The drive terminates the DATA IN phase when Allocation Length bytes have been transferred or
when all available Drive Status data has been transferred to the initiator. When Allocation
Length is set to 0, no data is returned. This does not cause a Check Condition.
Page Parameters

Page Length of the page.
Page Length is the number of bytes of status data following the Header
Page Code 01h
