    When I try to set up Time Machine, I only have the choice of one of my two external drives (NOT the one I want to use for it, of course). Is this because they are daisy-chained? It's the only thing I can think of. Very odd.

    Is it a Intel Mac? If so then the ext. drive needs to be formatted as GUID. Try un-daisy-chaining it and see if TM sees it then...

    I'm having the same problem. What is GUID format? I have a LaCie external with two volumes. It is not daisy chained.I've erased the volume I want to use and formated in apple extended journaled. Help!

    It's for Mac Intel machines.

    OK thanks. I realized my external was not in GUID. I partitioned my Mac HD using leopard, booted off Tiger on my external, then cloned Tiger onto the partition on my Mac HD. I then reformatted my external with GUID partition. ***** Time Machine still won't recognize. I've erased, I've reformatted, I've rebooted. It shows in Finder and I can copy to it.

    I give up. Time Machine sucks, because of that Leopard sucks, I've had it.

    And yes, I'm on Intel C2D.
