OK, I bought an Airport Extreme Base Station primarily for wireless Time Machine backups. I'm trying to connect a 300GB Maxtor drive in a Vantech NexStar enclosure to the router and after hours, I still can't get it to work. After reading of many problem with formating USB drives under Leopard, I finally booted up my Tiger install disks, opened Disk Utility and erased the disk. This finally got the drive working with TM when directly connected to my Macbook via USB. (The USB disk format issues with Leopard are unacceptable BTW) So, I did a full TM backup while the disk was connected to the laptop to speed things up. I then connected the drive to the Airport Extreme and tried to mount it. No luck. The Airport Utility could see the drive but TM said there wasn't enough space for a backup. I tried to erase the disk remotely and start over but that didn't work. The Airport Disk Utility has never seen any of the storage I have connected to the base station. I guess the next step is to get the Tiger disks out (AGAIN) and reformat the USB drive one more time. Will I have any luck doing an initial TM backup wirelessly? I know it will take a long time but at this point I willing to do it if that's what it takes. I truly disappointed about all the problems I'm having. It's almost like being back in Windows land. "It just works" does not apply here.
