I am trying to set up a Time Machine backup through my AEBS USB Disk.

The USB disk is formatted GUID with a single partition (1TB Fantom) and appears in the shared menu and mounts in the finder on all three of my computers on the AEBS.

I just cannot get it to show up in Time Machine as an available drive to back up to.

I partitioned using GUID as many posts suggest.
Drive appears in shared menu and mounts in finder
In Time Machine drive does not appear as a destination from all three of my computers on my network

In Airport Utility
Firmware version 7.4.1
File Sharing Tab: Enable File Sharing is checked
I have tried "with accounts", "with a disk password" and "with airport extreme password".
Remember this password in my keychain is checked
Airport Disks Guest Access: Read and Write
Share Disks over WAN (I tried checked and unchecked)

I am running 10.5.6 on all three Macs. A G5 tower and two MacBooks.

I have read a lot of troubleshooting posts on this issue, but I believe I have tried everything I should. I imagine it is something simple at this point.

Any thoughts and guidance greatly appreciated.

Time machine only works with directly-connected drives, or with the Time Capsule.

Network drives will not work.

There's a hack you can use to turn it on, though, at your own risk.

Search the forums; it's been covered a dozen times and more.

My understanding is that Apple re-initiated Time Machine over AEBS with the latest AEBS firmware 7.3.1

Spheric is incorrect. AirDisk has worked for Time Machine backup for quite a while now (though it didn't with the initial release of Leopard).

I'm sure you've done this, but did you mount the Airdisk before or after trying to select it as a TM backup?

Something else would be to try hooking the disk up directly to the machine you want to backup. Select it in TM preferences and make your initial backup (which is what you should do anyway because it will take forever over wireless). Then reconnect the disk to your AEBS and make sure you can then connect to it for backups.
