I purchased a 4 TB Easystore/Easyshare drive several months ago and have been using it exclusively with my iMAC. I formatted it to ExFAT, and it was working fine. Recently I resumed my project of copying photos to the external drive, but it will no longer let me write to the drive. I can’t create a new folder on it either.
WD Utilities are up to date. Do I need to reformat the drive?
