I have an external firewire drive (Esquest) that I use for video editing. I've had the drive since 2005. The problem is it keeps causing problems on all the macs I've used it on (PowerBook G4, iMac and MacBook). The drive works well but after ejecting it and shutting it down, if you power it up again it doesn't show as 'mounted'... I have to go to Disk Utility to remount it. Sometimes it won't even show on Disk Utility or it seems it makes 'Disk Utility' hang... the whole computer will become slow (when powering up or shutting down). The only way to fix the problem is to switch off computer and the wall power! (Apparently that resets the FireWire Bus...). Is this problem unique to my external drive or does everybody experience this with Firewire? None of my USB ext-HD's has this problem.. Any suggestions short of getting another drive?
