To improve things, we need to talk about common user scenarios. Problem is, normal users will approximately never have to format a disk, and it's a perfectly adequate interface for nerds.
If this were the 90s and everyone was still using floppy disks, yeah it would be worth making it slightly more user-friendly.
This interface was perfectly acceptable in the 90s, and it's perfectly acceptable today. Dropping a big graphic with a large circle button labelled format would have been worse. I say this as someone who writes my fair share of aesthetic user interfaces.
My takeaway is different. If your "temporary code" is sufficient to solve the problem, then it may last 30 years. If it was an actual problem, it would have been fixed by now.
