Weird problem occuring on one of my external hard drives; in the library it acts as though the files are exactly were they are supposed to be (they are), but when i go to work in develop or export, I get a "File not Found" error, but no option to locate or search for that files new location. The other hard drives are working fine and not dispalying this problem. I even moved one of the folders out of the bad drive to a different one and was able to access them, edit and export. I tried syncronozing some of the folders and its calclauted to delete all the iamges in the folder because it was reading that the folder in the drive is empty, when it isn't. Thanks for your help.
Thanks for the quick reply; by adding LR to have full disk access solved this problem, I am so relieved. The drive seems to be working well with everything else, except with its backup protocal; for some reason I have multiple backups stored from today and yesterday when normally it is only one
