The PDF files i keep and modify on my “MyBook Live” Type: WDNAS:1 “open read only” half the time not allowing me to make changes. It started out occasionally and now it happens almost every tiime I open one. I work with a lot of different PDF’s and the problem is random. when I move or copy the same file to my desk top i can open the file with no modification. As soon as i move it back to within the directory of my External HD it locks it again. I change the folder root properties to no avail. I have installed the software for the HD on my main computer and have have the Share settings on Public. I have no problem with other file formats such as word, Excel autoCAD etc… jus the PDFs. can you help?
