Why Is My External Hard Drive Read Only On Mac

Why is my external hard drive read only on mac screen
  1. The Seagate hard drive read-only mode can be easily changed in a click by using a third-party NTFS reader - EaseUS NTFS for Mac. EaseUS NTFS for Mac is a robust NTFS mounter, which features to change the drive from read-only to read-write mode on the hard drive, external hard disk, SSD, USB drive, Thunderbolt drive, SD card, CF card, etc.
  2. Another common cause for the external hard drive 'Read Only' problem on Mac is the formatting errors of the storage device itself. If you see a warning that says the device is only being mounted in read-only mode while connecting, your hard disk is diagnosed to have formatting errors that prevent you from writing files to it.

I recently purchased a WD external 1TB hard drive from target. The sales associate assured me several times that the device would work on MAC and PC out of the box (Target’s fault not WD). I took the device home and downloaded some footage from my PC expecting to be able to pull it up on my MAC laptop, which did work, but when I tried to put new footage from the MAC on the hard drive, I got the message that the hd ws “Read Only”. So I decided to visit the Western Digital website and see what was up. I found the tutorial for reformating the hard drive for use with both MACs and PCs, but I am ot very tech savvy, and I’m concerned about the risks. If the situation were reversed, and my PC could only read the files and copy them, it wouldn’t be a big deal, but I need to be able to store things from my MAC laptop to the hard drive. If anyone has any advice I’d greatly appreciate it.
