Originally Win 8 and converted sucessfully to Win 7 HP. Ran for about a month then the owner contracted an internet social disease trashing it badly. "No Problem!" I thought! ( Went through the same procedure as the first time, Wiped the drive, NTFS format loading from T-Drive (T- Drive is good) Windows begins to install but cant find HDD, asks for driver. I have all available drivers that Toshiba has on site already unzipped on another T-drive. Windows recognizes it just fine and will let me browse and select one but none of them will work. I need the "Mass Storage Controller" a legendary creature that no amount of Googleing can sniff out. Any Ideas?
