I'm having a bit of trouble with a HDD. I believe it's dead and I plan on RMA'ing it tomorrow, but I thought I should just check up here first to make sure there are no other options.
I posted a similar question on askubuntu.com two weeks ago but as yet I haven't got an answer that helps. I don't intend to spam this question all over the place but I feel it's a legitimate question for SU as I believe it doesn't particularly deal with Ubuntu or *nix in general.
Initially the HDD was just acting in an odd way. I could change permissions, etc. but some files were being missed and I wondered if some of the sectors were failing. This progressed to complete drive failure. It wasn't detected during POST and a look in BIOS didn't turn up anything.
I switched it to a different SATA port and to my surprise the drive worked again. I concluded that the SATA port was defective. But then after another week or so of use the old problem recurred. Odd behaviour when setting permissions, followed shortly by total failure.
I again switched SATA port. This time I switched to a JMicron controller. (I have Intel, JMicron and Marvell SATA controllers on this particular board.)
The drive isn't detected during POST.
Is there anything at all I can do? It's formatted as ext4. I wonder if changing the location of the superblock might help?
