My drive can no longer be seen ...

[SuperdeeeDuper]

Help. I had already cloned my drive over to my 160 GB LaCie. I was doing a disk image copy over as well and realized that my drive was going to fill up and not have enough space. Well, instead of stopping the process I let it continue thinking it'll stop itself. Well, my computer crashed (not sure if it was because of SuperDuper or something else). When I turned everything back on I plugged in my LaCie drive and now it won't show up in the Finder. I hear it running but it's not being recognized. SuperDuper doesn't see it either. I do see the drive in the Disk Utility but I can't do anything. It shows the drive but none of the segments and partitions. What should I do?

EDIT: False alarm guys. I left the drive plugged in for a few minutes and it eventually showed back up and my data is still there. I did a Smart Update anyway just to be sure and to put the latest stuff on there. Thanks anyway.
