SOLVED Synctoy poblem with multiple USB Drive backups

[Temanu]

I want to use SyncToy to backup data folders to external USB Drives. I want 2 backups. When I remove the first drive and plug in an identical 2nd drive, SyncToy thinks it is the same drive and finds no files to backup. Sometimes (But not always by any means) I have had it work after a reboot. This time however a few days after the 1st backup, it ill not recognise the 2nd drive as a different drive and says there are no files to sync when a directory clearly shows there are. Any ideas please ??

SyncToy maintains a hidden list of files on each device which it checks to see what was last copied/updated so if you want to make backups of the same folders to two different external Drives then create two different named backups merely having the same sources and destinations such as Backup-Ext1 and Backup-Ext2
