iomega REV drive

So - I've got an iomega REV (35Gb removable hard disk) drive, and am trying to use MicroLite's BackupEdge software. 9.2 and earlier worked fine - with SuSe Professional 9.3 it broke, and it's still broken with 10.0 The issue seems to be related to blocking. It WRITES just fine (returns no errors) for any size files, and it will READ small files just fine, but when I try to back up a whole directory, it returns a bunch of errors - edge says "Directory not in proper format"; but there's nothing in /var/log/messages or anywhere else that I can find. Has anyone else seen this? Has anyone else got a REV working with 10.x Thanks in advance! Clay Jackson
