Just checked the Avaratec website. The only drivers they seem to have are for XP.http://www.trigem.com/us/support/drivers.asp
This site claims to have them, but charges $14.99http://www.do-download.com/System/Backup-Restore/Averatec-7100-122862.html
In the meantime, I'd Fdisk and re-load XP. The compatibility Wiz only works for programs, not drivers. If the company hasn't made drivers for Win 7, you may be looking for a new laptop.
