Replaing 225 with ST-251 on Rainbow (HELP wanted)

I just purchased and installed a ST-251 in my Rainbow 100A and
formatted/initialized it using WUTIL 3.2.  MS-DOS partitions
work fine, but CPM partitions are not correctly understood by
the CPM v2.0 which I have. (The major symptoms:
	a) at boot time there is a message about "files not intact.."
	b) a CPM partitions' DIRECTORY sectors are not
	   located correctly by CPM - so it thinks there
	   are no directory slots available or very few. 
	c) if `maint' is used to delete all "phantom" files,
		then files can be written to partition, but
		the new directory entries show up in the wrong place
		vis-a-vis the partition utilities idea of where
		the CPM partition starts. (So I expect that if
		I used the disk in this state I'd certainly corrupt
		other partitions?)

I can supply more details.)

I suspect this a "known" problem.  Is there a known "fix" or 
patch? (Either to CPM.SYS or the boot loaders?) I'd hate to
have to permanently give up all CPM programs - some are quite useful.

Thanks for any ideas.
