IF the disks are as we suspect (master and slave relationships) and IF
you now have either a failed or a removed drive, then you  MUST correct
the jumpering.
Sure, you can often see a disk that is misconfigured.
It is almost certain, however, that when you write to it you will simply
cause corruption on it.

Of course, so far this is all speculation, as you have not actually said
what the disks, controller interfaces, and jumpering and so forth are at.
I was merely speculating, based on what you have said.

No amount of software magic will "cure" a hardware problem..
