[KasticK]

I have a serious problem here that i've been experiencing for over a year now,I have 3 firewire drives and i usualy work between OSX with M Box, HD and TDM & 9.2 TDM systems.Going Back & forth between all formats with no issues until July last year one day.I started getting and error message saying " This Is not an Audio Playback Volume,and asked me whether it should copy all audio files to a suitable Playback Volume" it does'nt load any of the file sin My session,but then when i go to a TDM System or HD it loads and plays perfectly well, this error message only happens when i try to load up a session on my M Box system .If anybody caN ASSIST ME WITHT HIS I'D BE VERY VERY GRATEFULL TAHANK YOU.

You need to make sure that your Firewire drive is set as a Record volume in the workspace window. Under the Window menu, go to workspace, make sure there is an "R" under the "A" column. Right now there is likely a T or a P (Transfer and Playback)

This preference seems to get changed sometimes if you open Pro Tools without the drive mounted or if you use the drive on another machine, etc.
