UniBeast does not allow to select destination

[Khan]

Unibeast does not allow me to select destination. Tried with two different USB flash drives and get the same error. Keeps asking to rescan but never finds the USB. Thanks!

It's telling you your USB drive hasn't been prepared correctly or is too small. It worked fine here.

Tried with a third USB drive 7.65 Gig and it worked. Other drives where just 7.46 Gig and did not work. Thanks for the heads up!
