ATA commands

NTDEV

Is there an example in the DDK that shows how to send ATA commands to
a hard drive?

Greg

Not in current DDK’s. I think you would have to look at some code from
the NT4 DDK.

I looked under the DDK and there appears to be an IOCTL called
IOCTL_ATA_PASS_THROUGH, has anyone exp. using this IOCTL, any
suggestions/advise.

What layer are you looking to do this at, and more specifically what
commands are you trying to send? (Are you dealing with ATA devices or
ATAPI devices? You said ATA, but I’d like to make sure we are talking
about devices that do not implement the PACKET command set from
ATA/ATAPI standards). What OS?

IOCTL_ATA_PASS_THROUGH is limited and not available on all operating
systems.

I will be talking to a sata hdd and will be at usermode level if possible…
I guess I could write a filter driver if needs be, but would obviously
prefer not having to do that. I want to send down the SMART command, so
synchronous IO is OK. I will be implementing this on a windows 2003
machine.

Thanks,

Greg

There is a seperate IOCTL set for SMART.

…and this is the only way in Windows to send raw ATA commands. No other ways.
Windows just lacks this facility.

You can only send the SCSI commands which are supported as a part of
ATAPI.SYS’s SCSI emulation, but not any ATA command.

IOCTL_ATA_PASS_THROUGH is pretty much undocumented, any examples someone
could point me to?

Who is/are Ur vendor(s) for the sata ?. They should provide scsi pass thru for this. ata is mostly proprietary with very many incarnations !!! Also, I’ve seen problems (during early stage ) of scsi_pass_through for sata …

You will need to build your code using the Server 2003 headers in the latest
DDK. The generated code will work on XP SP2 and Server 2003, but not 2000,
XP, or XP SP1. The documentation is also available in that DDK and though
there are no samples using it, you can use it to produce a functional
driver.
