Thanks for all the answers guys, I'm at work and rehearsing so haven't been able to try anything yet. @ parlapitas, I tried FAT32 on XP but didn't work. @ anthonie, yep no switch, the switch in the photo is on the adapter, i've ordered one off ebay though but it's not going to arrive for a few days, and may not work. I'll try your filesystem check when I get home - about 6pm @ switch It's XP, can you let me know how please so I can try. Thanks again Dan
