Cannot regain storage after deleting multiple backups on WD Passport
This is a second posting for clarity. My external WD Ultra Passport external drive won’t release space after deleting several large Backup files. Drive is 1TB and it keeps showing 51.1 GB available no matter how many backups I delete and I do NOT want to erase the entire disk as I need the one backup that I still have left. I can’t transfer that file either as I get format incompatibility messages. I want to use the drive to start backing up my MAC M1 before I upgrade to Sonoma but I still have the IMAC 27” that the remaining backup belongs to - does anybody have any ideas?
