2.6.10: dmraid gets mirror on HPT374 assembled wrongly

Tue Jan 18 17:58:05 UTC 2005

A bit more information.

This is the partition missing from Linux, as Windows sees it.

There's 20 GiB of empty space on the mirror array.  I was
contemplating using it for an encrypted partition (but never got to
it, as Linux didn't work with ATARAID at the time).

C:\>diskpart

DISKPART> list disk

Disk 1 is now the selected disk.
