I have a problem with my zip drive and I was wondering if you guys can help me out. My zip drive was working perfectly fine on my Mac since I bought it. I just bought a new PC laptop. Out of curiosity, I plugged the USB zip drive to my laptop. Well, it works great with my laptop. Now I brought it back to my Mac. It either can't detect a disk in there and it isn't able to write on the disks. I had to restart in order for the zip drive to detect anything. All I could do was drag FROM the zip disk to the Mac, but I can't write or copy ONTO the zip drive. It just gives me an error (-36) and says I didn't properly unplug the device by "ejecting" it. I didn't even unplug anything! I plug it back into my laptop to make sure the device isn't busted and sure enough, the drive functions perfectly fine under XP. This sucks. Any advice is appreciated. I've been using zips for years for school work (I go to an art school and they use zips a lot) and I've transferred files from PC to Mac and vice versa all the time. I'm running OS X 10.2.6 on the dual G4 and Windows XP on my laptop. I'm seriously considering a USB pen drive now. A classmate of mine has one and it functions really well from PC to Mac and vice versa. =/ As for the external hard drive question. I've been thinking about getting a firewire/USB hard drive just for data storage for both my PC laptop and the Mac (for videos, MP3's, etc). I was wondering if I'll have any formatting problems or will both machines just read it as an external storage device? I'd hate to dump $150 on one and it only works well with one machine.
