Promise fasttrack raid, changed disk, unable to boot.

Paul,

I recently ran across something similar after having received a warranty replacement drive. Mine turned out to be some real funky geometry being reported by the ide-disk layer. I came up with a fix, that worked for me, not sure how universal it is. See the thread at:

http://marc.theaimsgroup.com/?l=linux-kernel&m=105840994419059&w=2

My patch that is attached in the first message of the thread is not recommended, but the final simple fix worked also in my case. Does Linux perhaps see the other drive with strange geometry? You can check with

cat /proc/ide/hd?/geometry

In my case, the head count reported by Linux was 255, which was bogus and caused the problem. Hope this helps,
