You should upgrade or use an alternative browser. I have 1 64GB Sandisk Memory Stick which is presently 'formatted' as 'Windows NT File System (NTFS)' and want it to go back to 'Mac OS Extended (Journaled)'. It will not do it and says 'Erase process has failed' There is another message which says 'Couldn't modify partition map. : (-69874)'. None of this means anything to me. is there a way to do what I want in the Terminal? Otherwise I have got a useless 64GB drive. I have a MacBook Air M1 if that's any help.
Thanks
Brian
