os-prober grub on EFI error on probe
by Nishtya from LinuxQuestions.org on (#6J6MV)
I got a new bigger SSD and I have been using the old one as a playground for trying new shiny or old reliables for nostalgia. Everything is UEFI and that partition sits on the internal disk. Gotten pretty good adding and removing the entries as go and come. On my next to last new acquisition I noticed the following when I ran os-prober on the grub update. From when it pops up it seems to be an issue with the old ssd which is now a removable on USB.

Found Linux Mint 21.3 Virginia (21.3) on /dev/sda4
Found PCLinuxOS on /dev/sdb1

Found Solus (4.5) on /dev/sdb3
Adding boot menu entry for UEFI Firmware Settings ...
doneSomewhere along the line with Manjaro I think it was a grub show stopper after install where it was looking for btrfs system which I don't have anywhere on either disk. I deleted the manjaro and wrote another distro or two to that partition and now things boot normally no problems. But when I update grub and it probes it is getting a hint of a phantom fs. gparted and other disc tools are not seeing anything unusual here is fdisk

All seems to work fine - should I be concerned? That now external ssd is just for playing around with distros and flavors but I also use it as the backup for my data from my daily driver, kubuntu. Should I attempt to fix something that isn't broken or is it unreliable with this file systems warning. The shared partition I use as backup for buntu and windows is ntfs.
