Looks pretty good overall to me; however, I do have a couple things to note:

* It's possible to also wipe individual partitions using this (as the code
  suggests) so maybe a it would be beneficial or more user-friendly to change
  the text of e.g. the button to "Wipe Partition" if the user clicks on a
  partition instead of a disk? Or maybe just change it to "Wipe" to cover
  both cases?

* An error will be thrown if one attempts do wipe a disk / partition that's
  currently mounted:

# proxmox-backup-manager disk wipe sdd
wipe disk sdd
Wiping block device /dev/sdd
TASK ERROR: command "wipefs" "--all" "/dev/sdd1" "/dev/sdd" failed - status code: 1 - wipefs: error: /dev/sdd1: probing initialization failed: Device or resource busy

  Maybe this case could be handled in a more user-friendly manner as well?
  E.g. checking which disks / partitions are mounted first and then showing an
  error with a more expressive message.

* There are a couple things clippy seems to complain about, but nothing that's
  an immediate code smell.

Overall it looks pretty good to me though; the things I mentioned above are
somewhat bikesheddy can also be addressed in a follow-up.
