Uhmmm....What should I make of this comment...
The folder you posted the details for stated the \root had ownership of the folder. I have to assume since you have been using this device for two years, you are familar with this situation. I cannot go through the permissions in the Owners manual and try to check what may need changing since I do not have a device like yours. It seems like a good device to have, but something seems to have changed recently that is causing problems.
I asked you earlier if there was a difference in the folders that exhibit the problem and those that do not. Since you state those are the only folders you do not have admin privledges for, I would think that is a clue. Why do those folders show ownership as \root if none of the others do.
Right now, I am limited to suggesting perhaps the size of the folder might be involved or the content. Can you see anything that might suggest folder size in relevant to your problem. If it isn't the size of the files in the folder or the content, or the fact they are not on the computer that originated them, I would suggest you go back to the manufacturer and see if they have seen any problems with the device.
You may be able to copy a folder to another location, even though you do not have ownership or permissions. Someone set the files to read only..was it you?
