https://bbs.archlinux.org – Hi,since yesterday I can't delete or create new files on my primary USB flash drive.I then tried my other USB drive and it works without a problem.Both are from the same manufacturer and formated with the FAT16 file system. When I check the permissions of the files/folder I see myself as owner with read/write permissions on both drives.the error message on the console is:rm: cannot remove 'foo': Read-only file systemI'd really like to give you more information but honestly I don't know where to look since one works and the other suddenly stopped working.\edit: Checked (HowTos)
