Time Machine on ext drive. Can't use drive for other backups

[qveda]

I have a MacPro, OS X 10.5.7. I have TM configured to back up to an external 1 TB firewire drive.

I use Adobe Lightroom for photography. it provides a checkbox to allow you to backup all photos as you import them from your camera card. Adobe recommends selecting an external drive for these backups. But for some reason, it does not allow me to select the external drive that TM uses.

Is there any reason why Time Machine might be preventing me from backing up photos to the drive, or to a new folder on that drive ?

You can just partition the hard drive using "Disk Utility" and it will appear on your computer as two separate drives. I'm sure that will enable the photos to be backed up.

Ive been doing this for almost everything I use personally and at work. Ive split up everything from 1TB, 4TB, 9TB and even a 24TB G-Speed Fiber box using TM.
However your problem with Lightroom is a strange one. Would it be persmission errors?
