Ok so, this is pretty weird. No matter what I have tried, I cannot remove the ./rockbox from the root of my Sansa e280. It spits out a "Cannot delete file "./rockbox/blah/blah". Read-only files system" error. I checked permissions on this directory and I have full rights. I also get this error as root. I can delete and add files from the rest of the directory structure. It's only the rockbox directory that is throwing this error. Recommendations?
