- 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.
- 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.
