Normally there are icons for each hard drive partition on the desktop, similar to what you see for your USB devices (but marked with names like hda1 and hda5 for ide type hard drives). If you don't have them then it's very likely that something happened to the partition table in the crash or that the drive itself is no longer working. If it's just a partition table you may be able to recover it easily with Knoppix, see the man pages for gpart and testdisk for details. But be warned that not all windows crashes can be recovered easily (I have 2 hard drives that I still can't get the files back from).
