similarly misdocumented so that ATA_FLAGS_DATA_OUT really means "Readdata
from the device."Regards,George.

Your link is broken, but the online documentation of the
ATA_PASS_THROUGH_DIRECT structure is reversed from the Jan 2005 MSDN Library
documentation.
The Jan 2005 MSDN Library agrees with your conclusion that
ATA_FLAGS_DATA_OUT means read from the device. However, my working code
that uses IOCTL_ATA_PASS_THROUGH_DIRECT sets ATA_FLAGS_DATA_IN when reading
data from the device, and the online docs usually reflect what the next MSDN
library will look like, so I'm thinking that this is a recent doc fix, and
your problem is elsewhere.
Care to post your code?
Phil
