[Digikam-users] Problem with new hard disk containing existing images

I have had my own fights with it, but finaly know how to handle it. I 
think the usage of the UUID is usefull for safety, not to mess up 
different db´s and probably for other reasons I don´t know about. If you 
think it is wrong and want to have it changed, I advise to make a bug 
report, that gives the best change for programmers attention.

If you sofar not have it the way you intended, I might be able and 
always willing to help, I dealt with it several times before.

Best regards
