It's formatted with FFS and has 2 partitions.
When I checked the device manager with both USB's plugged in, it showed up there but no drive letter was assigned in Windows. I had to unplug one of them (the second being for extra power) so I don't know if Windows lost it.
I didn't have time to try it again yesterday with both plugged in because I was setting up an old 933MHz Gateway E1600 for my parents with a clean install of Win2k. So much fun...
Once I get the checksum error fixed, it goes back into the SX-1. Eventually, the whole setup may go for sale by the end of the year. I just want to make sure it all works. My Wii will be giving me an internet connection in the living room with the bigscreen. The CD32 looks nice using the S-VHS out connector. If Nintendo starts charging a monthly fee for using the browser after 6 months, I'll just have to hope the hacker community get AROS on Wii to bypass that...
