Hard Drive Stops?

[JimmyJam]

I recently installed a 500GB SATA Hard Drive in my computer. I partitioned 80GB to Windows, 2GB to Swap, 512MB to /boot and the rest to /. When I leave my computer idle, I return to find it off. The only way I can get it back on is to unplug it from the wall and plug it back in. I am wondering if this could be an issue with APM on the Hard Drive.

I ran:

$ sudo hdparm -B 255 /dev/hda

and received:

/dev/hda: No such file or directory

So I tried /dev/sda

$ sudo hdparm -B 255 /dev/sda

/dev/sda:
 setting Advanced Power Management level to disabled
 HDIO_DRIVE_CMD failed: Input/output error

Any help would be greatly appreciated, preferably before my new hard drive dies.

Thanks

What does it do? Shut down?

Same behavior in Windows as in Linux?

I'm not entirely sure what it does. It appears to shut down, but I can only start it back up after I unplug it from the wall and plug it back in. This does not happen in Windows.
