Edit in PS from LRC makes PS stall when images are on external SSD

[Charlie_Butterworth]

I spent a couple of hours on Friday with Adobe online chat. Ther nature of the problem was that whenever I try to edit an image in LRC in PS, PS would stall.

In the end, we created a new test LRC catalog and imported images into it. Then the import worked. The new catalog and images were stored on my HDD rather than external SSD. Anyway, we figured that the problem had been solved.

The problem recurred when I rebuilt my entire catalog, which I store on a SanDisk external SSD. To be specific:

1. When on the HDD, jpegs, Raw files can be opened in PS directly from LRC

2. When on the external SSD, jpegs and Raw files cannot be opened and PS stalls

Can anyone suggest anything, please!

Thanks,
