Please help WD question

Why do you suspect the drive? With the information you provide it possible (and IMO more likely) to be something else. E.g. powersupply, loose powerconnections, RAM, Graphicscard. etc. Do you overclock? Try memory test.

Hammerbot is right, I almost always find that instant restarts are a bad power supply. Freezing and then not seeing the drive tends to be either the harddrive, or more likely, the ide ribbon needs to be re-seated in the drive and on the motherboard.

Go grab the Western Digital diagnostics wdgdiag or the IBM drive fitness test. See if it reports anything for the drive.

Yes I initially thought the same... but i thought the board, after i was told psu is fine... so i baught a new board and it did it again.. besides the restarting which can be a million things... after it reboots sometimes it cannot find the drive till i reboot it again then it will see it. its a strange problem..

I checked the power consumption of the 100GB drive versus other 40GB drives and at the very worst, the power consumption has stayed the same with a 17W pull at startup, but at the best, it actually dropped.

On the amps side though it increased a little bit. Really depends on which 40GB drive you had.

It still sounds like a power issue though. Consider installing motherboard monitor and checking to see if all your rails are ok.

As I mentioned.. i put in a different harddrive after replacing video and motherboard... and problems seems to have ceased.. So im pretty confident its the harddrive.. else it would happen still with this replacement drive

Asus Probe is the same thing   i had motherboard monitor on before it... 5v line holds around 4.85-4.83
rest was normal... but the 5v line according to most is normal... my friend using same psu with 5 drives.. and he is having no problem with power consuption
