On Digidesign Pro Tools, I get the following error when opening any project: “The original disk allocation for this session could not be used…” and then “Audio files are on volumes unsuitable for playback. Would you like to copy them to a suitable volume?” and cannot open any projects. What can I do?
That means the drive is not designated in Pro Tools to be an audio drive, this is a known, not uncommon, glitch that sometimes happens with external Firewire and USB audio drives. This does not mean there is a problem in your system, but likely just that a drive was accidentally disconnected while Pro Tools was open.
In Pro Tools, go to the Windows Menu, choose Show Workspace, and make sure under the A (for Audio) column the drive in question is labeled with an R (for Record). T (Transfer) and P (Playback) do not allow recording. Changes should take effect immediately and without restart, you can simply load or create your session immediately.
