I got a JTag from a member on here, and while I wait for a replacement DVD drive, I put XeXMenu 1.1 on my HDD using Xplorer360.
It boots, but it won't detect my 1TB External My Book. I formatted it to FAT32 using Partition Magic and it won't detect the drive at all. I had it in the back USB port.
I'm trying to format it with Fat32Formatter now, but here's the kicker: my Xbox itself DID detect the drive(it came with 9199 dash). Is there anything special that I have to do for my USB drive in XeXMenu(other than putting my games in the "games" folder)?
