Hi - thanks for taking the time to answer. Yes, you are right. I'm pretty sure I probably set the drive letter, so that BIAB could find the files every time. It was awhile back so my memory is fuzzy, but I think at the time, I was working on pictures on another external drive, so wanted each to maintain its own letter. I'm not sure if I should try to change it back at this point. I don't want to have to change the prefs in BIAB to tell it where to find the real tracks, every time the computer auto-assigns a different letter each time I plug it in.

From my research online, it seems a lot of folks are having the issue that these days external hard drives being seen as "non-removable" anyway, even if they didn't assign a letter, as opposed to flash drives. As I said, I'm a bit nervous about it, since windows corrupted one of my eternal drives before. I was just curious how others who are using the BIAB drive are handling this. I know some people run the BIAB program from their external drive. I'm curious about others who have the program on C drive and keeping the real tracks on the BIAB hard drive.

Thanks again for your response. It's one of the things that makes the BIAB forums so great.
