I was having hard drive issues last night. Ran seatools and it failed. I shut off laptop for the night.
This morning went to get a hard drive and the windows setup wouldn't find a hard drive for install. I check the BIOS and it showed a drive after I re-seat the cables. Every time as of last few boots, the bios will show the hdd but when i run the windows 7 setup at the screen for I would usually format it wont show me any drives. I have tried 2 discs (I don't have any more to test) and also I used the new drive and my old one and both same results.
I have reset the bios also. I'm hoping the SATA controller isnt hosed. The The laptop is out of warranty and has been running properly. I'm albe to run live OS (linux) but nothing hard drive related.
