Read only Privilege on External Hard Drive
I am logged on to MacBook Pro (2017) as myself, and I am shown in Users & groups as *****me, the Administrator.
Now, after several months since the last time, I try to reconnect to a SABRENT External Hard Drive I am advised in "Get Info" that "You can only read".
Although, in Sharing & Permissions, I am listed as *****(me) with Read & Write Privilege, it appears that the Hard Drive has not recognised *******me, and thinks I am "staff" or "everyone"
I have unlocked the "Get info" and tried to assogn Privilege "Read & Write" to everyone, but do not have the authotiy
MacBook Pro 13", macOS 10.15
