I am trying to delete files from my Sansa Express which I use as an external USB drive. When I try to delete at the folder level, Vista tells me the "storage is write-protected" and that I should remove write-protection and try again. I am able to delete the files individually, however, with no problem at all.
When I go to Properties, the folders are read-only. The individual files are not read-only, and they delete fine individually. The problem is only encountered when I select a folder and try to delete it. I can not disable read-only from Properties, because it is grayed out.
It may or may not be relevant that most of these folders were loaded onto the drive from my other computer, which runs XP. However, not all those folders are running into this problem: only the ones which say "read-only" in Properties.
Things I've already tried:
There is no write-protection switch on the device. There is a hold switch, and that is definitely in the off position. So a switch is not the issue here.
I've gone through the lengthy and confusing process of taking ownership of files before, but there is no way to do that here. The only tab in the Properties screen is "General" and there's nothing in there I can click on or change.
I've also tried running Windows Explorer as Administrator, but that doesn't help either.
Formatting the drive is not a practical solution for me, because I can't just format it every time I encounter this problem.
