I received a USB flash drive that contains a pre-installed ISO 9660 (Joliet) image on it. To delete the image and free up space on the drive, I attempted to use
sudo rm -rf /Volumes/ISONAME via a Terminal; however, the command failed as the image is a
Read-only file system. How should I go about deleting the ISO?
For reference, I'm running OSX 10.9.5.
Thanks so much!
