I couldn't find any resolve from anyone on this topic in older forums, but I have the folder generated and backed up on my iMac and my backup drive, a DROBO. I managed to get rid of the lost+found items on the iMac, but the DROBO says "The operation cant be completed because the item dir_1558208 is in use." as well as the rest of the contents. Its on an archive drive and NOT being used! Any ideas? I know what the l+f is, but don't need anything from it. It takes up about 100GB and really want to lose it!
