verify ATA devices

OSR_Community_User · February 20, 2002, 11:37am

Hi all!

Do we have any API (under Win2K) to verify availability of an ATA device?
I just want to check to see whether \\.\PhysicalDriveN is ready.
Note: this drive can be unpartitioned.

Thanks
Vu

I don’t think a symlink will be there if the hardware is not discovered yet.

Hi,

Just send TEST_UNIT_READY SCSI command to this device. Use SPTI for this or
whatever you want…

Anton

Thank you Anton!

However I have looked at this section before. There is no
obvious command like “TEST_UNIT_READY” in those IOCTL_SCSI_XXX;
Can you help me out a little further?

Thanks again
Vu

Hi Maxim!

If disk Managemer can see the drive then the LUN, port, and
TargetId are available. I could send
IOCTL_SCSI_GET_INQUIRY_DATA to the device. PhysicalDriveX
actually works at this stage.

Hi Vu,

Right. There is no such command. This is SCSI command that you need to
send to the device. See spti.c sample (AFAIR it send such a command) in
DDK. Keep in mind the fact that if the device is not claimed(there is
nothing like
\.\PhysycalDriveX:) you’ll not be able use Partition Mgr services, TEST
UNIT READY will still work. Think about it! -)

Regards,
Anton

Thank you Anton!

However I have looked at this section before. There is no
obvious command like “TEST_UNIT_READY” in those IOCTL_SCSI_XXX;
Can you help me out a little further?

Thanks again
Vu

TEST_UNIT_READY is not implemented as an IOCTL, but is implemented as a
SCSI command (CDB). So, you will need to build your own SRB and CDB and
send it to the ATA device via a passthrough.

ATAPI does implement the SCSI TEST_UNIT_READY_COMMAND, See NT 4.0 DDK
ATAPI.SYS miniport driver to see the specifics on how it is implemented
(faked).
