Hardware Access

[Guest]

I am using WindowsXP

There are a set of commands that can be passed to an ATA drive to preform several Security and SMART functions
DeviceIoControl seems similar but does not implement the required command set or give access to the required registers and the _outp() command of course does not work in XP. Also I want to do these functions from a standalone program rather than replacing the device driver

I am using WindowsXP.

There are a set of commands that can be passed to an ATA drive to
preform several Security and SMART functions.
DeviceIoControl seems similar but does not implement the required
command set or give access to the required registers and the _outp()
command of course does not work in XP. Also I want to do these
functions from a standalone program rather than replacing the device
driver.

I'm afraid this sort of access must be provided by a device driver - in
particular, the ATA driver. You might want to re-post
on microsoft.public.win32.programmer.kernel with a more specific description
of what you're trying to do and what constraints you have.
