I have an external 3.5" Firewire drive connected to my eMac at all times. If the eMac goes to sleep (say when I leave it unattended for awhile), the Finder gets a bit wonky with the external drive. It's still mounted, but I can't access it (the Finder freezes when I try.) I can turn the drive off which basically gets things back to normal, but then I get the warning message about not properly removing the device. I don't think any harm will actually be done, but since my family uses the computer this is sort of inconvenient. Does this happen with all external drives? My drive enclosure was relatively cheap, so I'm wondering if a different enclosure would do the same thing.
