After a search here I see there are many partition threads, but this may be unique. As is my recent custom, on May 14th I did a Windows 7 disk image backup of my boot C out to my external USB. No problems. I also did a Macrium image of C to the external USB, no problems.
Then, one day since then I noticed some un-allocated space on the USB and used EASUS to expand the storage partition
into that space. No problems, and Windows 7 still sees and handles everything on the USB just fine. Except...
Just now I wanted to see the date of the last backups and get ready to do another. The Windows 7 Backup tool reports it "can't find the disk... where the backups are being stored".
Then there's an Options button. Clicking it, I got as far as selecting the USB as the new destination and Cancelled (because I want nothing running, and C cleaned and defragged first).
BTW, Macrium's Restore panel seems to have no problem seeing its saved image. So, questions: should I go ahead and finalize selecting the USB as the new destination in the Windows 7 Backup tool? Is it likely the tool will succeed in seeing the location next time? Is there something else I should do first?
