I tried with my dock, I don't have another machine that can use this HDD that is easily accessible.Try with other machine if problem is same then go with disk utility.
Hello,
1) Have you tried looking for it with Disk Utility?
2) Boot from the recovery partition and see if Disk Utility sees it from there. (It will eliminate a whole of of variables from your regular login.)

Hello,
Just to make sure: did you try to boot using the recovery partition, *not* to try and reinstall, just to access the disk utility from a "neutral" and safe boot volume.
Last thing, do you have an old Apple DVD you could boot with, using an older OS?

Ended up being a physical issue. Some odd coating on the DATA pins of the drive. A screwdriver and some alcohol wipes fixed that!
