I'm running a PowerBook G4 with two external hard drives for my media files. When I run iPhoto, I store the files on the external hard drive to keep my local hard drive empty. Last night I was doing some system maintenance and noticed a number of Volumes on my local hard drive that were taking up a lot of space. I deleted them along with some other large files I don't use. This morning I tried to open iPhoto and I got an error message stating the hard drive was locked. Is there a way to unlock this external hard drive so that I can regain access to those iPhoto files?
The files and folder still show up in Finder and I can go through the folders but I can not open the files. Time Machine is also affect and can not back up because it's a read only drive. I can open other files on this computer. It seems to be affecting the mac programs. Please help.
