A better question is do you need to? If you need the low-level access, sure - it's a standard, well-tested module. But if you're just opening, reading, writing, seeking, etc. there's no good reason to go low-level.

getLogicalDrives() can be a handy function, especially in conjunction with GetDriveType($Root). On the other hand, using IOCTL_DISK_SET_DRIVE_LAYOUT, IOCTL_DISK_FORMAT_TRACKS, and others can trash the hard drive with a simple typo. They're potentially useful, but I wouldn't play with them on anything other than a test box.
