To check if a drive is NTFS-formatted, open Disk Utility and select it from the sidebar, and you should see its format listed among other details at the bottom of the Disk Utility window. Permissions not ignored Being a multiuser operating system, OS X sets up access permissions for all files and folders on the system, including external drives, which are merely accessed as a folder once attached and mounted.

Since permissions are set up through account UUID and UID numbers, if the drive is used with different systems, it may have permissions associated with it for accounts that your current system does not recognize, or even odd permissions settings that can prevent access to the files on the disk or to the disk itself. This may happen even though getting information on files and folders shows you ought to have full access to the drive. To prevent such errors from happening, OS X includes a setting to ignore permissions on external drives, so all files on the drive should be fully accessible regardless of their permissions settings.

Note that these permissions settings will only be available on drives with formats that support them, so if you are using a FATformatted drive, the option to ignore permissions will not be available. 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.
