This is weird. I have been running 2 500G Seagate Barracuda drives through the X33 port on my MacBook Pro. The interface is a SeriTek/2SM2. It was awesome, very fast. I use one drive for audio and the other for SFX and Video storage and playback. It worked great until I upgraded to 7.4. Now
Pro Tools will not allow me to change the the drive assignments from transfer to playback, or to record for that matter. Both drives are formatted correctly, i.e. OS Extended (journaled). My drive enclosure have the correct Oxford chipsets. I have trashed prefences and data bases but I still can't open any files in PT. Any Ideas?
Digi says to do all of the above and I've done it. Would it help to transfer all the files to another drive and then re-format? I really don't want to go back to 7.3.1, as I think the elastic audio function of 7.4 could be really useful in my work. (same problem when trying FW 800.)
Any help would be great. Thanks
