[ntdev]ATA WRITE Command Help!

NTDEV

Hi All,

I am trying to issue an ATA WRITE (0x30) command using
IOCTL_IDE_PASS_THROUGH. DeviceIoControl function returned status OK but the
status register value is 0x58… Since DRQ bit is set to one does this means
I have to perform the PIO transfer manually… I tried issuing a READ
command on the same address and the data returned is not the data I am
trying to write before…

Also, do you guys know another way of issuing a WRITE command?

Thanks in advance!!.. :slight_smile:

Regards,
Newbie

ATA pass through is basically broken in 2000 and XP SP1. It is working in
Server 2003 and XP SP2, and will require the use of IOCTL_ATA_PASS_THROUGH
from the Server 2003 DDK.

Also, READ/WRITE are not commands defined in the ATA-6 spec. Did you not
mean READ DMA, READ BUFFER or another ATA-6 read or write command?

Based on the opcode he stated (0x30). I’m guessing he means WRITE
SECTOR. (One of only two WRITE commands manadatory for non-packet
devices).
