MacRumors members have been very helpful to me. Now I have something else that might stump you. (But I doubt it!) I use a G4 iBook and a G4 iMac at work. At home, I use a G3 iBook, a G3 iMac and a G5 iMac. Here's my problem: Recently, I resurrected the above-mentioned G3 iMac. (iMac 350) I used my 2 GB, EP USB 2.0 flash drive to access some work files, did my work, then re-saved the files to the flash drive. Now, at my work iMac G4, I can't open from or save anything to my flash drive. I do not have the same problem on any of the other computers! (Yes. I've made sure that I have read/write permissions, but I still get the errors messages.) Anybody know what's up? Looking forward to your replies. Thanks, in advance.
