WD Element portable 1Tb drive not seen after Big Sur download

Had a download of Macos, got an notification saying drive incompatible yet I can see it - what do i do to get my data?

Hello,

Please be informed that it is a plug and play drive which comes preformatted in the NTFS file system which is supported by the windows computer. However, if you want to use this drive on a Mac computer you will have to reformat the drive in MAC OS (Extended Journaled) format.
