Drive rotation

[paulp]

Hello Dave, June 2008, I asked you about how to configure it so that SD would use two hard drives for backup. (Case 69687). You very clearly explained how to do this and all has been working very well up until a couple weeks ago.
(The solution you gave me was use SDDiskTool to set each drive with the same UUID).

Since I updated my SD to the latest version 2.6.2 (v87) this solution "seems" to have broken in some way. I've re-run SDDiskTool and indeed - the UUIDs were different so I made them the same again. Now each schedule still fails with the message "SD can't find the drive Backup". Are you aware of this issue please and do you have any ideas for how I can resolve this?

Thanks,
Paul

Have you deleted and recreated your schedule?

Hi, Yes I've done that, and I've also erased and partitioned both drives to start again from scratch.

If you partition the drives again, you'll change their low-level IDs. It sounds to me like you haven't properly set that up.

OK possible but - I partitioned each drive for apple partition scheme and gave each the same drive name as before.
Then I did the SDDiskTool routine afterwards. Each UUID was indeed different and I set each of them with the same UUID before then rescheduling a backup.
The backup schedule worked for the first drive attached but then always fails for the second (no matter which is connected for the first run).
I checked the UUIDs were the same only yesterday and they were.
cheers, Paul

I have no idea why that would be, Paul, except if the drive doesn't have the same low-level ID. I assume the 2nd backup works if you don't swap drives?
