My Seagate Barracuda 7200.12 ST3500418AS SATA 3.5" HDD does not load into Windows anymore even though BIOS recognizes it. The failure happened about 3 to 4 weeks ago.
After completion of POST, it reports Windows did not shut down properly and offers the options to continue in either Safe Mode, the last know good configuration or starts Windows normally. I have tried both the Safe mode and Normal mode and it does not load into Windows in either case.
I have also tried the Seatools diagnostic software. The acoustics test can make it go idle and make it spin back up. But it fails both the short and the long tests reporting it has bad sectors. I have run the Seatools long test on it several times now. The first time after the failure Seatools does the scan up to (from memory) about 10% of the total drive capacity before getting stuck. Now the long test does not scan any area of the HDD at all and reports bad sectors virtually right away.
Your help is appreciated. Thank you.
