I've been reordering photos without a problem until now, when this message; that I've never seen before, started to pop up.


The issue appears to have something to do with "the source", but what is "the source". I thought it was the location of the images, on C:, but I'm in the folder where these images are stored.

Once this message appears, and I close it, I can no longer select a photo to drag to a new location.

I have all filter off and I'm in Library Mode, and in "Custom Order".

I shut Lr down and reopened it and the pop up hasn't, yet, returned when I tried to reorder my images
After I posted this I got this message again and couldn't continue until I shut Lr down and reopened it.

But now I know why it's happening. I've been having trouble, of late, with my external drive; where the catalog is stored, going unrecognized. When that happens I get this error when I shut Lr down.

I've learned, when that happens, to check my ext drive because, for some reason, it loosed touch with the computer and the system stops seeing it. If I switch the USB port Off and On it come back up again and this error stops.

This is also the cause of the "source" error; the "source" was gone missing. When I shut Lr down and switched the USB port Off and On, the drive came back on line and the "source" returned and I no longer got that "source" error. Until the drive dropped out again!
Might be the cable, or the HD could be going bad..

But a more likely reason that I'm thinking is that, judging by you saying you switched off the USB port, you have a multi-port USB hub. I've encountered similar issues with those - where the device will work if plugged into the computer itself, but has issues like you describe when on the USB hub. (Not happening with my LR catalog&raws though - those are on an internal SSD/HD.)

I'm thinking it's related to how much power those things are getting supplied with.. My next thing to try is to add yet another mains-powered USB hub to the chain and see how that goes when reducing the number of things connected to each.

It's a SSD and only a few months old and I didn't have this problem with the Asus, just on this new machine.

It hasn't happened since I posted this but I am moving it to a port om my machine, that should address the power issue.
