I know that the reason for this is my fault and the warranty is probably void now, but this is the best place to ask...
A while back I was doing some experiments with this hard drive and I was in some utility to access SMART info.
In this program (i think it's a WD utility, but am not sure), the were some values that could be changed. So, I changed one.
Afterwards, the HD stopped spinning up and I was sure I had bricked my HD. A few months later I plugged it in to see what would happen and still it would not spin up. Just a few days ago, I was in a frisky mood and began again to try and revive this drive. When I plug it in and boot, BIOS cannot see the drive, therefore Windows could not see it either, and it would not spin up. I downloaded the DOS version of WD HD diag, and put it on a bootable flash drive. I rebooted on the flash drive, and ran dlgdiag5. Lo and behold! It sees the drive, and reports it to be in perfect condition! So, I reboot (ctl-alt-del) and booted to windows which now sees the drive. Now the drive works perfectly under windows (even spinning down for a rest and spinning back up when I access it), UNTIL I turn the power off. When I turn the power back on again, the same situation ensues. I have to boot to DOS, and run dlgdiag5, then reboot and all is good. Even the SMART info is great.
Does anyone know what setting I changed and possibly how to change it back??
The HD works great, and I can use it as is because my machine stays on 24/7
But it would be nice to have it back to normal.

Thank you so much for the information. It's all begining to make sense.
I looked and I did have a jumper on the drive, which I don't have one on my others, so I took it off.
I get the same results though, as I said, I changed something via software. I downloaded the program from
Hitachi and it did not work, it wouldn't change the settings of the drive, only show them. I guess it has
to be Hitachi?
Well, I am on the quest for a utility then...

I tried everything I could to disable PUIS on the hard drive but was unsuccessful.
I downloaded HDPARM and turn_off_poweron_in_standby by HDPARM and every time
I try to set the PUIS to disabled it returns a failed error.
The article you linked to about no spinning up (flash bug), may also apply to me.
I am just glad I didn't brick it!
If there are any more suggestions, I will be willing to try it.

Well, I doubt you did anything to the warranty. So, if worse comes to worse, you could RMA it.
