Why is the WD My Passport read-only?
Sometimes, the WD external hard drive is read-only on Mac when you just got a brand new WD external hard drive. In other times, it suddenly became read-only after you have been using it for a while. The most common reasons for a read-only WD external hard drive, like WD My Passport, are listed below:
- 1. Your WD My Passport hard drive is NTFS-formatted
- 2. You have read-only permission to access WD My Passport hard drive
- 3. Your WD My Passport hard drive is corrupted
If you are not sure which reason has caused your Mac external hard drive read only, check the scenarios one by one. If you know the reason already, you can jump to the scenario that best describes your situation.
Scenario 1: Your WD My Passport hard drive is NTFS-formatted
For WD My Passport Ultra and WD Elements, check if the hard drive is formatted with NTFS file system. By default, macOS can read NTFS drive on Mac or drive in read-only mode. You can view the files saved on the NTFS-formatted partition or drive but can't make any changes to them. In addition, the WD My Passport hard drive won't let you add any files to it. To check if your WD My Passport is NTFS formatted, follow the steps:
- Go to Finder > Applications > Utilities > Disk Utilities.
- Click the WD My Passport (you may have changed its name) at the left sidebar. The file system information will be displayed on the right.
Note: You can also right-click the disk icon on the desktop and choose "Get Info" to check the file system information.
After having confirmed that the WD My Passport is formatted with NTFS, many people will choose to reformat the WD My Passport hard drive to make the WD external hard drive compatible with Mac. But as you know, directly formatting WD Elements or My Passport on Mac causes data loss.
In fact, installing a WD NTFS driver for Mac is a much easier way.
