I used the Startup Disk Creator to make a bootable USB stick and now it can only be mounted read-only.
Output of sudo mount /media/user/Volume_Label/ -o remount,rw
:
mount: cannot remount /dev/sdb1 read-write, is write-protected
Output of mount
command:
/dev/sdb1 on /media/user/Volume_Label type iso9660 (ro,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500,uhelper=udisks2)
Output of dmesg
command:
[108080.964308] sdb: sdb1 sdb2
[108080.966929] sd 12:0:0:0: [sdb] Attached SCSI removable disk

How do I make this USB stick writeable again?
mkfs.vfat
does not modify partitions. You just created the filesystem without any partitions. That’s also valid and supported on USB thumb drives, even on Windows.
