Locked myself out of Mac Formatted WD passport external hard drive
I Did a general verify disk permissions to my mac formatted WD Passport external and it's now locked me out of doing anymore time machine updates, moving data etc. It keeps saying it's now "read only" and can't see how to change the permission back.
I've read some of the other threads and it all draws to re-formatting my external but that will wipe everything. Surely if I've some how changed it to "read only" that I can change it back to "read & write"
Any help would be much appreciated. Thanks
MacBook, OS X Mavericks (10.9.1)
