mkfs may run at heavy-load time. The only safe time to do timing-sensitive
probing is at device driver initialization time, and that is
inconvenient. And it may still fail due to caching and buffering
in the disk itself.
The task isn't easier for swap partitions, although a simple
optimization can be done by preferring to use the fastest side
of the partition first. This can be determined by a simple program.
