The effort to examine the drives to figure out how they would go
together in a raid 0 is the same effort to figure out how they go
together in the original raid 10,n2.  So, no.

But look again at my e-mail from earlier today for scanning the
individual drives.  Please also answer whether you used '--assume-clean'
each time you recreated the array.
