You are seeing the (hex) contents of the error register of the
disk controller chip:

Bit 7:	Bad Block Detect
Bit 6:	CRC Error
Bit 5:	Not used
Bit 4:	ID not found
Bit 3:	Not used
Bit 2:	Aborted command
Bit 1:	Track zero error
Bit 0:	Data address mark not found

So response = 4 means Aborted command, and response = 10 would
mean ID not found.
