Dynamic disk mirror Boot problem

[allenEd]

Hi

I have set up a w2000 server SP4 with 2 disks, disk0 and Disk1. They are set by W2k as a soft mirror. The c drive (mirrored) is the system disk. There are no other volumes, but a couple of Gbs free unused disk space.

When testing this for failure, I disconnect Disk1, (slave), fine...boots up great. When I replace the disk...fine, back to normal. Problem is when I remove Disk0 (master). The system will not boot,

I have made a single floppy W2k boot disk with the amendments to the boot.ini file, which boots fine when pointing to Disk0,

e.g.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Server" /fastdetect

When I change this to

[boot loader]
timeout=30
default=multi(0)disk(1)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(1)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Server" /fastdetect

It wont boot...

am I missing something here?

thanks
Allen
