I have a Westinghouse Serial ATA Drive 300GB that has a lock showing on the desktop icon, but there is no box in the info window that I can uncheck to unlock it as I have done in the past. I tried accessing it through Terminal, but it would not let me (or I don't know the proper code sequence). Right now I can access the drive, read and write. The one thing I cannot do is create a new folder on the drive, unless I create it WITHIN one of the other folders already there. Can someone please tell me how to repair this? Can I do it by installing Mac OSX on this drive? PS. It will not allow me to verify or repair permissions either.
