My regular exterternal audio hard drive which is an OWC firewire 800 drive, which I´ve been using with protools 6.7 fluently for more than a month now is SUDDENLY not recognized as a valid audio location for protools sessions. I have panther 10.3.9 I can't imagine what happened. I don´t touch my setup at all. which is a powerbook, a digi 002, monitors, microphones and the external drive. There is a lot of work inside that "invalid" drive, which had been always recognized as the default audio location, so any help would be really appreciated.

All you have to do is go to the workspace window in protools with your drive plugged in. There is the name column and right next to that is a column labeled A and next to that V. In the column A there should be an R relating to your drive. What the A stands for is audio, V for video I think. Pro tools has this thing so you can change your drive to playback drive (P), transfer drive (T), or record drive ®. You want it to be a record drive. To change it just click the letter in your drives column and a pull down menu should pop up that lets you choose. I've had this change in pro tools without having done anything to it. I guess sometimes pro tools feels like giving you a little scare.

Very unusual. Pretty scary too. Is this behaviour what some people call a bug? Has it been corrected in more recent releases? Anyway Banevt, you were right on. I did exactly what you wrote and everything´s back to normal. Thanks a lot.
