This begins with a fresh new install;l of Mint 20.1 or Ulyess. I opened"Disks" just to check things out. But the Disk software has been greatly reduced to nearly useless. It use to show all my drives and could format them how ever I wanted it to.. Now it only shows my main drive. So I opened "software Manger and went looking for a more complete Disk manager. As usual they had several things that looked promising. I installed several to try out.But then I couldn't find them anywhere. So I tried to move on. Clicked on my computer Icon and got zipo! It would not open. Looked like a job for reboot and I went for it. NO BOOT! instead I got a tiny tiny message dead middle of my screen instead of booting it gave me the boot! It said I don't know you. I do not want to know you and I will not boot for you...or something like that, Even with my nose on my screen I could not really read it...But I caught it's vibe! ":O} Fortunately I forced my self to stay up and do a back up last night which made me whole again. But this is the first time Mint has actually screwed up my Mint. So unless you know more that I do...Hey that could happen! And don't like the reduction in force of the new Disks app Don't go crying to the Software manager she has nothing good to say about it. All she said to me was No\w you know why you felt the need to see 3AM getting a backup. Now for the help I'm asking for. Can you fix "disks"? I mean without demolishing my install of course!
