I have had 3 archives on an external drive for a couple of years now, updating them at least once a week. On that external drive I also have a Karens Replicator backup of 'my docs' These have existed happily together until this morning. Occasionally I have had to change the drive letter if I have had other things plugged in but it hasn't happened too often, and it's easy to change the archive location in FD-ISR anyway. This morning when I plugged in the external and fired up Karen I noticed the drive letter was one out so I changed it in Karens settings and pressed the 'my backup job' button. I watched in fascinated horror as it deleted everything on the drive at the speed of light and laid on a fresh backup to the drive of 'my docs' My FD-archives are gone and it won't recognise the drive no matter how hard I try. Windows sees it, Karen sees it, I can see it, but FD-ISR cannot or won't. Would formatting the external help? Uninstalling it in device manager perhaps? Any suggestions are welcome.
