Mac Os Format Disk Terminals

Initially external disks may be formatted for Windows and after you connect it to your Mac it appears in the device list in the Finder, but is a read only disk meaning that you can’t write to it in its current format.

The when the disk is selected in the finder bottom left symbol with the crossed out pencil means that the disk can only be read not written to. Why this is, is because they come formatted as Windows NTFS drive which OSX can only read, so we need to reformat them so we can read and write – thats where a handy utility called Disk Utility comes to the rescue.

Disk Utility

Disk Utility is found in /Applications/Utilities/Disk Utility.app, open it and select your external disk in the list on the left.
