I installed a new PASSPORT portable drive and successfully backed-up files in “FILE MODE” from one hard drive on my PC.
When I tried to back-up files in “FILE MODE” from another hard drive, I saw the directories tree displayed in the left pane but I could not mark any of the directories selected for back-up.
There was a notice of “ready to perform backup” but no “start backup” button was displayed.
I did not back-up any files from that hard drive in “CATEGORY MODE”.
Thank you for your help.
