transini Posted July 17, 2008 Share Posted July 17, 2008 When I plug in any USB stick or SD/MMC card, Ubuntu 7.10 mounts it read-only. In the terminal I try to do: $ sudo mount -o remount,rw /dev/sdb1 mount: block device /dev/sdb1 is write-protected, mounting read-only In desperation, I upgraded to Ubuntu 8.04 to see if this fixed it, but the problem remains. My fstab is the unmodified, original version that came with Ubuntu. What is going wrong? Thx Link to comment Share on other sites More sharing options...

Since I had my USB stick plugged in when Ubuntu flaked out, forcing me to reboot, it got branded with the 'unclean' flag. To reset the flag, I had to plug my USB stick into a Windows system and reboot it, which apparently 'blesses' connected filesystems in some way. Now Ubuntu allows my USB stick to be mounted read-write. Kind of a pain. I don't remember having to do this before... Link to comment Share on other sites More sharing options...
