Question: External HD correctly formatted returns error
I have got a WD External hard disk and it has been formatted correctly to Mac OS Extended Journaled.
I then transferred loads of files to it with no problems.
Today, I was doing the second back up session, and I tried to merge two files on the hard disk so I keep whatever on the hard disk PLUS the new stuff I am pasting.
However, I was stopped with an error message:
"The operation can’t be completed because an unexpected error occurred (error code 0)."
This message means the external hard disk is formatted as FAT or FAT32 and therefore it shows this message when I am trying to transfer stuff bigger than 4GB.
But the hard disk is already formatted as Mac OS Extended Journaled.
Any idea how to solve this issue? or why it is happening?
I am using High Sierra.
