Help! "Session is saved on a volume set to 'Transfer' only"

[nuemes]

Need help asap - have a session to finnish tomorrow and suddenly can't access files on my external hard drives(!)

Mac Dual 2 GHz PowerPC G5, OS 10.4.9

1. ProTools 7.3.1 opens up fine.
2. When I click on a a PTLE session file on *either* of my hard drives it brings up the following message:

"This session is saved on a volume set to 'Transfer' only. If permitted, set the volume(s) in question to 'P' (Playback) or 'R' (record) in the Workspace. Otherwise, choose OK to save a copy of this session and its media to a valid playback volume. The session copy will automatically open from the chosen location."

3. When I click 'OK' as it requests and try to save a copy it tells me that the chosen file is "not a valid playback volume"
4. I rebooted the computer, hard drives and my Digi 002. Same thing happens.

I should be able to open the session without any of this business as I have in the past.

I HAVE NO IDEA WHY THIS IS SUDDENLY HAPPENING. YESTERDAY IT WAS FINE. I"VE NEVER SEEN THIS TYPE OF MESSAGE BEFORE.

PLEASE HELP.

Thank you

Windows Vista SP2. ProTools Mpowered 8. No problems till today. WTF?

I am horrified. Tried this 'workspace" solution and it wouldn't change to R. It says "this is not a valid audio volume". How in the heck did this happen? I have been recording with this drive for over a year...and out of nowhere I suddenly am told (by the computer) that the C drive is for transfer only.

I saw another post suggesting Re-formatting. I have 600g of software and audio files on this drive. I have to start over? There MUST be an alternative to reformatting? Does anyone know what CAUSES this change in my drive (to transfer only)? I worked on a song this morning........and now I'm trying to open file as usual and all this starts happening. Help! Pleeze?
