WD formatted to handle iphoto (MAC) corrupted? says READ ONLY

Hi! Need some help! Can’t access my iphoto library because the drive reads: 

“Caution: the i{hoto Library is on a locked volume. Relaunch iPhoto when the volume has read//write access or relaunch iPhoto with ,option key held down to choose another library”

I tried to change settings (I am the admin, it’s my personal laptop), nothing works and I cannot reformat it because all my photos are on! (> 200 Gb)

Hi and welcome to the WD community.

See if the steps from the following link help. 


Hi, sorry, no this is not the problem. The library is on my external but it suddenly went into read-only mode. The threats that you recommended do not apply. 

What format (NTFS, HFS+, FAT32, exFAT) are you using for the external hard drive?
