Hi, Hope anyone can help with this? Acer Aspire 5336 Laptop running Win7 Home Premium OA. At boot, windows fails to load giving the above error. Tried to restore factory settings but fails at 52% stage with i/o error. BIOS shows SATA Port0 Disk status=frozen. I have a 'boot any non-loading system to win xp' disc which i tried and loads the 'mini' xp system and Disk Management shows the C: drive as healthy. Not sure whether this is a case of replacing the hard drive or whether it can be recovered ok...if its a new hard drive i've got more problems as there is no recovery disc! Any ideas would be most welcome & thanks for looking.
