Do you have an objection to my original suggestion of 1750GB in that
case?  It saves faffing around with fractions and it's unlikely to
confuse the user.

BTW, I do appreciate Simon's point about df showing a different number.
How about we print:

sd 7:0:0:0: [sdc] 1099511627776 512-byte hardware sectors (563TB / 512TiB)

(or perhaps a more realistic number ...)

sd 7:0:0:0: [sdc] 976562500000 512-byte hardware sectors (500TB / 455TiB)

It's perhaps a more gentle way of informing our users that they may not
have quite as much capacity as they thought they had.
