Oliver is on this list; why not ask him?

I think they may be talking about USB keys or flash memory sticks.
These are not the same as hard disks.

*Some* system firmware treats memory sticks as being like floppies.
Floppies do not need partitioning; the filesystem is written direct to
the medium.

*Some* firmware can only boot from a USB key formatted directly,
without a filesystem.

However, the correct way is to partition it, then format the partition(s).

For hard disks, I would call this a necessity.

The disk is defective. Return it and ask for a replacement.

No, you cannot reformat a disk that you cannot format in the first place.
