Per,
Well.. it were a question for CE, I would suggest you much more interesting and easy to use API to accomplish what you wanted. :-)
But under Windows Desktop, I don't know any good documented APIs that helps you as much. Some info could be retrieved from
GetDiskFreeSpaceEx/GetVolumeInformation/FindFirstVolume/etc.
So, I guess, your decision to stick with DeviceIoControl was right.
Btw, there are some good useful 3rd party "hard disk" SDKs exist. This one I like: http://www.paragon-gmbh.com/n_hdm_sdk.htm.
This is not to say you are better use the SDK but just FYI...
