I run PT 6.8.1 on Windows XP, and recently purchased a second hard drive to store my music files to keep my system drive from getting filled up. I transfered the music files to the new drive and went there to open them to make sure they worked, and they did. I then deleted the files from the system drive to free up the space. When I went back to open the files again off the new drive, they would open part way, and then say something about some of the music files being "on a volume unsuitalbe for the playback of music files"--speaking of the new drive---and ask me if I wanted to copy them to a suitable volume. If I put them back on the system drive they work fine, but that would defeat the whole purpose of getting the new drive! As far as I know the drive is the same as my system drive, only larger. I'm thinking it has something to do with how it's partitioned. When I partitioned it, I didn't know exactly how to do it, so I put it as a "simple drive" or something like that. I dont' know much about tech stuff, but need to have this resolved to use the new drive. As you can tell, I'm pretty new to all this. I've only been running PT for a couple months. Does anyone out there know what I need to do to fix this? Thanks!
