To avoid the same discussion, take a look at the archive of this mailing list.
I know the limitation already.

You mean, as Linux-2.6 does? That's interesting.

I'm also interested in the way NetBSD does. IIRC, it computes the checksum of
some sectors of each disk. EDD v3.0 is much more reliable, as multiple disks
may have completely identical data (e.g. software RAID), but the advantage of
this way over Linux's is that it works even with older BIOSes.

It is really necessary to discuss this issue more seriously, I think.
