Check drive for errors Formatting errors can also cause a drive to be read-only. While in many cases formatting errors are relatively minor and tolerated by the system, there are times when the system may determine it safest to only mount the drive in a read-only state to prevent corruption to the data on it. When this happens, you should see a warning when attaching the drive that states it is only being mounted in read-only mode, and in these cases you should first back up all contents on the drive.

Then use Disk Utility or another robust disk or volume repair tool like DiskWarrior to check the drive for errors and attempt to fix them. Sometimes errors can go unnoticed on a drive, so if these tools report the drive is working OK, then consider wiping the drive and repartitioning it. This can be done with Disk Utility by selecting the drive device in the program's sidebar, then going to the Partition tab that appears and choosing "1 Partition" from the drop-down menu.
