I’ve got a 320 GB My Book on a Mac G5 PPC running 10.5.8. When I started the machine this morning, the drive mounted just fine, but the disk and LED would not stop spinning. I’m not running any files directly from the external drive, as I use it for backup and storage. When I try to eject or drag it to the trash to turn it off, it tells me the disk is in use and could not be ejected, even though I don’t have any applications running. Anyone have the same problem or have any advice?
