+1 again on the file manager - something like FILEEXPERT works well for me.
Didn't think you need to root your tablet for that. With the latest update to 3.2, for Honeycomb, has improved support for read only NTFS.
Question is:Think twice before updating to v3.2. I lose my root privileges after that.
Better search for the one with updating to 3.2 with root thread so you'll be saffe.
