I recently removed the 5400rpm harddrive that came in my Digital Audio, and replaced it with a 7200rpm drive. The problem I'm having is that every time I have to reboot, I get the gray screen with the flashing icon, which I assume is the computer looking for a boot disk. I then have to power down, press the CUDA button, then power back up to boot from the new drive. I have to do this every time. Anyone know how to fix this?
