I have a brand new external hard drive which frequently ejects itself on a regular basis (every ~20 minutes or so), seemingly only when I have Aperture open (my Aperture library is located on the external hard drive). The disk works perfectly fine for long periods of time when I am not using Aperture.
I have read many places online that this could be related to disk inactivity sleep, disk journaling, Spotlight indexing, faulty Firewire cables, faulty Firewire ports, hard drives which are about to die, etc. However, the disk seems to work perfectly fine when I am not using it for Aperture and none of the many forum threads I have found have pointed me in the right direction.
Does anyone have any ideas on how to identify and fix this issue?
Thanks in advance.
