my wd15ears 1.5T hdd is down. have no clue how it happened. no clicking nor beeping sound noticed from the hdd. it was used in my HP desktop and just suddenly can't be recognized no more. i moved the hdd to another computer and went into the bios and looked. the hdd shows up in the CMOS yet clicking into it for detail settings, it shows 0 on capacity as well as cylinder, head, precomp, landing zone and sector. can anyone shed some light to how to fix please?
