How do I quickly delete time machine backups
My Time Machine backup tells me it is too full to do further backups. I thought it was meant to delete old files automatically, but presumably that's not happening. I'd be happy to delete most — even all — backups and start over, but deleting through Time Machine is too slow to be practical. An option would be to reformat the entire Time Machine partition, if possible. Can I do that without reformating other partitions on the same (external) drive?
