I Installed TI 11 onto my lap top. When i first went todo a bu I got a "can't read from hard drive error" so I ran scan disk and chkdsk and they found nohthing. My HDD is not giving me ANY other issue except not reading in TI. So to be safe a did a back up to my NAS drive vis Vista as TI would not read it and I formated the drive. Loaded a fresh copy of vista and TI and tried to create a bu.Again I got the cant read from HD error. Downlaoded a few utils like Hd Tune and they say that the drive is good. But I can not use TI! Any ideas as to why?
