WD Scorpio Black 320 GB 7200 RPM Not Working
Don't know if anyone else has experienced this, but worth a shot.
I just purchased a WD 320 GB 7200 RPM Scorpio Black. It will not work in my brand new macbook. The original apple hard drive works fine, I have a USB->SATA adapter, hooked it up, was able to clone the old hard drive onto the WD drive. It boots up perfectly fine when I boot via USB using the adapter.
When it is installed, however, the hard drive keeps spinning up and down and up and down...to the point where it takes 25 minutes just to boot. I disabled the sudden motion sensor via pmset, reformatted the drive, reinstalled Leopard, had the drive replaced via RMA, used the drive jumpers to limit spinnup voltage, all to no avail.
Still the same situation. Drive works perfectly fine via USB on this computer and others, but will not work when connected to SATA on this macbook.
My theory is that it may draw too much power, being a 7200 RPM drive and is being constantly disabled do to overcurrent then enabled again, causing the spin up/down. Maybe this is why you cannot order one of these from apple with a 7200 RPM drive? In any event, I give up. WD can't think of anything and I am stumped. If anyone has any thoughts, let me know before I return the drive, otherwise, it's going back and I am getting a 5400 RPM drive. If you are considering buying one for your macbook, beware.
