I'm using a Western Digital 320 GB USB drive, which has been partitioned into 2 separate parts. The USB Loader application tells me I need to format one of them, but when I press A nothing happens. It resets when I press B, but I can't get it to format the drive as WBFS. I tried formatting both partitions as FAT32 on my computer but that didn't do anything, either. The drive I'm using was listed as compatible on the list of devices so... Any ideas? And sorry in advance if I'm asking a stupid question.
