Hi. I have an external drive where I back up all my photos and videos - it's 200 gig - almost full. I was transferring some images to my Mac when the firewire came unplugged. Now the Mac - nor any other computer can recognize the external drive (It's a Seagate). I've run the Mac disk utility on it - it shows four partitions - or two main and two subordinate partitions. I ran the repair disk and verify on one and it says it's fine - but still cannot read the volume. The second partition and sub-partition I can't even verify. This external drive contains all our archival photos and I can't just back it up to another computer because I don't have anything with enough memory to do that. Any suggestions to make it readable by computers (Mac or PC) so I can salvage the drive? Is there a way to eliminate the partitions? Thanks for your help!
