My users have to wipe and format drives on an almost daily basis in a linux environment and they are not very apt with the command line. I want to build a tool that will let them plug in their external drive and run the tool and let it format it for them. This could include:

  • USB
  • HDD
  • SSD

I would have recommended GParted but there are more specific needs (INode settings etc) that need to be used that GParted doesn't support so I need to use Parted or something else.

My question would be what considerations would i need to take into account when singling out an external drive, that is without selecting an internal drive in the machine and accidentally wiping it!

I understand this may be difficult but i don't believe that it can't be done. Is there anything in linux (CentOS7) that points to unique elements of mounted drives? I was thinking of using UUID and storing the internal drive UUIDs in a json file to refer to but i feel this is too static and can cause a mishap.

I'm using python to build the script, i have a running script but the user must select a drive from the CLI and a single slip of a key could make a mistake, i dont want to give the user the option to make that kind of mistake.

    You can set thinks up so that new drives belong to group floppy (rw), and built in drives are in group disk. Something about rules in USB sub-system. You then add your users to group floppy. – ctrl-alt-delor Feb 2 '18 at 18:55
  • Thanks for responding! How does one go about "grouping" drives? – jamalm Feb 5 '18 at 9:51

    I don't know, but here is a similar question I asked a while ago unix.stackexchange.com/q/168176/4778 (you need to look at udev rules). – ctrl-alt-delor Feb 5 '18 at 10:02
