Sudo Can't Open Read Only File System
messed up and accidentally made my usb stick into a read only file system. I have tried a bunch of things to delete the files, including the basic (rm -f myfile) and attempting to allow writing (sudo chmod +w myfile) and then deleting, but none of this seems to work. Any ideas on what I can do. I don't have anything on the usb stick that I need, but I don't want to throw away an otherwise perfectly good piece of how to change read-only file system usb drive equipment. How can I make it work? Am I going about this completely the wrong way? filesystem permissions read-only share|improve this question edited Jun 23 '12 at 23:16 Eliah Kagan 56.1k15162255 asked Aug 27 '11 at 20:24 Jonathon 230139 How to fix read only USB pen drive in Ubuntu –Suragch Jun 20 '15 at 10:31 add a comment| 3 Answers 3 active oldest votes up vote 13 down vote accepted Commands like rm and chmod are done on a mounted file-system. So if the file-system is read only those do not work. What you need to do is to mount the file-system as writeable. Some USB sticks have a switch on the stick to mount them read-only. Maybe that is the reason. It could also just be broken or damaged due to not correctly umounting it. Before you do anything: copy the files over from the stick. If it is not a hardware switch unplug and plug the USB stick and issue a dmesg | grep -i panic This will show you any panic messages. If you are seeing alot of them related to the USB stick and if it is a FAT partition you can use dosfsck to fix it. You can find out how it is mounted with mount and use dosfsck -a /dev/sd{xn} to fix an MS-DOS partition table or sudo mkfs.vfat /dev/sd{xn} to format the disc. Where {xn} is a letter and digit you got with

Or if it is missing putting some tape around the side where it used to be to make the reader think it is no longer write protected? –Anthon Jul 15 '15 at 10:58 It is a USB flash drive. –kRiZ Jul 15 '15 at 10:59 If there is no data on it, have you tried to make a partition table on it or just write something with dd if=/some/file of=/dev/sdc to see what happens? –Anthon Jul 15 '15 at 11:03 dd: failed to open '/dev/sdc': Read-only file system –kRiZ Jul 15 '15 at 11:09 There was data on it.

That said, now that we know that yours doesn't have a write-lock switch, maybe you cou
