I have a Western Digital Caviar Black 500gb 7200rpm 32mb cache HD. The HD was working perfectly for the first 4-5 months. Now when I turn the computer on in the morning the bios does not detect the hard drive until I manually reboot the pc a few times. After that my pc works flawlessly all day long. However I cannot put my computer to sleep or standby/hibernate, because after a few seconds of waking it up I get a blue screen and once again the HD is not detected by the bios until I reboot it a few times. I've tried increasing the time the bios allows the HD to try and boot up to 15 seconds, Ive tried switching sata ports on my mobo, and I've made sure the sata cable is securely connected, none of which has worked. can anyone help me out, I have no idea what to do?

I'm running Windows Vista 64 bit.

Run manufacturer hard disk diagnostics.

i had a similar problem i had to boot my pc 2-5 times to get it to work every now and again. i coundnt figure out what the problem was so i left it for 2 years it never got worst or better when i upgraded the mb there was no problem
try updating the bios
if you have a spare hard drive try that if it still happens then i say its the mb

I tried to run a quick 2 minute test but it hangs and never finishes.

it may be as easy as unplugging it blowing out the dust and crap from the mb and plugging it back in..thats worked for me many times in the past

So I plugged in an old hard drive and it reads it right from the start.. I guess its the hard drives fault, anything I can do?

I'm RMAing it back to Western Digital. Thank god i don't have to spend another 80$ on a new hard drive. Western Digital owns, even if their hard drives fail every few months :p
