Molle,

interesting, mixed hpt37x *and* hpt45x formated RAID sets...

Did you move one set from an older controller to a newer one
and create the other using the the new controllers BIOS ?

Could you send me the tar'ed and bzip2'ed output (*.dat and *.offset files)
"dmraid -rD" creates in a file named hptxxx-Molle_Bestefich.tar.bz2
and the "fdisk -l" output of the 2 sets, please.

Heinz
