(Re-sent with new subject as per Ronni's post)
Hi Alan, Just an off-the-wall thought - you aren't running Windows under parallels or fusion are you? If you are - is the USB drive being "captured" by Windows and so unavailable to OSX (though, if so, I wouldn't have thought Time Machine could see it either - unless it can "override" the Windows allocation). In Parallels, under USB preferences, you can choose from 3 options - so that connecting an USB device: 1) Connects it to the Mac 2) Connects it to the active VM 3) Asks which to connect to. So selecting option 2) would result in the device being "captured" by a running VM if it was connected whilst the VM was running. Just a thought. Cheers Neil -- Neil R.
