Hello,
I've been having some issues with my WD Caviar Green internal hard drive - and it's only been powered on for 13 days according to SMART data. I've had it for about a year, but I keep it unplugged when it's not being used, to try and preserve it.
Last night, I started backing up my documents onto the Caviar Green (as it's my backup drive), and this morning I proceeded to reinstall Windows 7 on my 500GB Caviar Black OS hard drive. While installing, I found out that the partition on my Caviar green was "misaligned by 512 bytes", so after Windows 7 had finished installing I temporarily copied all the contents of my Caviar green onto my Caviar black so that I could fix the misaligned partition. But after 15 minutes of copying, it threw me a "Cannot read from source file or disk" error for a few small unimportant files. Thinking that this was a minor consequence of a misaligned partition and nothing to worry about, I skipped those files but shortly afterwards it threw me the same error for a lot of my movies. This made me very concerned. Thankfully though, all of my important documents and backups are all right - they're all on my Caviar Black right now, but I've just started to get some "Cannot read from source file or disk" errors with some other things on that drive too, so in the morning I'll get some blank DVDs and burn all of the important stuff, just to be safe.
So to try and identify the problem, I have just booted from one of my Linux LiveCD's. I've opened Disk Utility and according to the SMART data I have 101 pending and uncorrectable sectors, 281 read/write errors and the self-test failed. For a drive that's barely been used, has never been moved or dropped and was fine YESTERDAY, that's very unusual because in my spare computer I have a 5 year old Samsung 80GB hard drive that has been in constant use since new - yet it has no bad sectors, no read/write errors and it flies through the self-tests. It's also unusual that the "pending sectors" aren't being reallocated like they should be. I haven't realized it until now, but my Caviar black has had 2 pending sectors since new last year, and despite being formatted several times they have not been reallocated.
I have been trying to fix this ALL DAY and I have such a headache. I'm almost certain that I'll have to RMA at least the Caviar green, which I don't really want to do as I'm concerned that I wouldn't get a replacement before christmas. Also, the only spare HDD I have is an 80GB PATA one and I can't afford a new one due to the hard drive prices skyrocketing lately.
I would really appreciate somebody's help and advice on this matter. Is it something that will go away after reformatting and repartitioning? Is it my fault for having a misaligned partition all this time? If so, does that mean I won't get an RMA on it?
Thanks for taking your time to read this, any replies or help are very much appreciated!
