Sorry I was too late, I'm in the middle of my finals here, bud...
Anyway, sounds like your prob wasn't exactly like mine. But I'll tell you what worked for me anyways: All I did was reformat the HDD > create a FAT32 partition for the backups (primary) and a NTFS partition for my backups (logical). The important thing here is the order, because from what I've seen, doesn't really matter what you number/lavel them, the order of creation defines the order the partitions are read by the Wii system.
If you need anything else PM me and I'll send you my skype address, I'm more active there. (Although I'm sure the guys here can help you much more than I can, specially Cyan, dude knows everything)
