Imac doesn't "see" my flashdrive

[darciem]

I have a flashdrive that I have used without issue before, but now my imac doesn't "see" it. It works on my macbook just fine. I have investigated the issue by checking DU, but it doesn't show up there, either. I have OSX 10.6.3 on the imac and OSX 10.6.2 on the laptop. Got any suggestions?

Whats file format is the flash drive formatted to? OS X can't read and write to certain file formats. The software that is required for it to write may have been already installed on your Macbook, and not on your iMac.
