drive empty? what does this mean?

[marilynpogo]

i have a version 2 saturn modded.(32 pin)

i put in a backup to play and it gives me a drive empty error. some games work but ome dont. its not bad burns because the games have played before and they also play in my version 1 with the swap trick. any help will be much apreciated

bad/burnt out, or improperly installed modchip would be my guess. either that or the laser assembly's had it
