Mount RAID on Knoppix/rescue Windows - help!!


I have an ALienware Area 51 7700 with two Seagate 100Gb 2.5" IDE's in an ATA-RAID (striping)


I get INVALID BOOT.INI.....Windows could not start because the following file is missing or corrupt: c:\windows\system32\config\system.

I know that means my registry is f^&*ked up, so I ran the recovery console off the WindowsXP CD (I reinstalled the Promise FastTrack 100 driver
for the RAID controler before getting into the console) and I tried the process described in the Microsoft knowledge base, article 307545
but when i try to make the new directory tmp I get Access Denied. When I try dir on C:/ I get:
Directory of C:\
There is no floppy disk or CD in the drive



I tried setup instead of recovery console and the Windows installation doesn't recognize any partitions. I checked the status of the array on the
FastBuild Utility:
Array No RAID Mode Total Drv Capacity(MB) Status
Array 1 Stripe 2 200060 Functional

I can't boot in safe mode, last known configuration, safe mode with command prompt....I can't boot Windows at all.

Right now I'm using Knoppix in an attempt to either change the registry from there, or salvage what I can and put it on an external hard disk, and then
restore the computer.The problem is I'm trying to mount my NTFS Windows partition in Knoppix so I can get to it, but I don't know how to mount an
already existing, BIOS-configured ATA-RAID in linux. Do you know how I might do that? Or, if you know any other way I could fix this problem, while keeping
my data, that would be appreciated.

My practical knowledge of RAID is limited - but I believe you can not mount a Win RAID under Linux without damaging it - least that came up in my research for a new PC with RAID...

So I would be careful in what you do. Might be that others have more experience and can give you a more detailed and better answer - but so far I CAUTION you.

May I ask a stupid question - 1) why a RAID in the first place and 2) why RAID 1

RAID 0, actually. And it's RAID because I wanted 200Gb on a laptop...those two seagate 100Gb drives were the closest thing I could find. Why a RAID in the first place? Not my choice....OEM-configured.

I ran RAID 0 on a desktop, my idea, for several years before I realized that if either drive failed, then all -- not half -- my data was lost. I broke the array down almost immediately. Had to buy a new 160 to have room, but it was worth it -- one of the original 40's that comprised the array has since failed.

Perhaps you should consider running your drive as separate drives.

Which should be the best advice, I mean the if I would be using RAID then I would most prob. be using RAID 1 for my /boot and for the rest something like RAID 3 or even better 5 || 6.

But all this going on about which RAID is the best doesn't help him in getting some of his data back under Knoppix ...

You're right, talking about RAID is like closing the barn door after the horses have gotten out.

Back when I was running that ill-fated striping array, I seem to remember it showing up as hdf & hdh; but also remember it being accessible in Linux.

I Googled on:
  • Your error message.
  • knoppix "hardware raid 0"
I got hits, but no answers.

the most productive was a Linux Google on:
"hardware raid 0" OR "hardware raid-0"

Take a look at:
http://www.linuxquestions.org/questi...583#post835583
"linux expert hde=noprobe hdg=noprobe" might put you on the right track.

Mounting / reading hardware RAID

Somehow your Ubuntu forum link goes to the 2nd page of the thread, but the HOWTO is the 1st post; this should go directly to p. 1:
http://www.ubuntuforums.org/showthre...7&page=1&pp=10
This should maximize the posts per displayed web page for those w/ fast connections:
http://www.ubuntuforums.org/showthre...7&page=1&pp=40

BTW, the Ubuntu thread seems to be for SATA, does it have value for PATA also?

same problem

I have the exact same problem on my windows xp home system running a raid 0 array. While I am proficient in Windows, I have never used linux and am a bit confused by the .iso files. When I click to download the Gen2dmraid live cd, I get a bunch of garbage mixed with text. Do you still have a copy of the cd/dvd you used to fix your system? Is it possible to share? Being confused by Linux, my panacea would be to throw a cd/dvd in the drive, fire it up and click fix (or at least follow just a few instructions). My sense from visiting the boards is there are a zillion other folks out there like me who have lost all data foolishly using a ntfs raid 0 setup on windows xp).

Looks like there was an easy fix after all. By the grace of God, I came across a post on another page that mentioned having to manually load the windows xp raid controllers in order to properly access the drive in recovery console (press F6 during windows load from the cd and install the fasttrak promise driver from a floppy disk). Once finished, choose R for recovery console, chkdsk /r and reboot. It worked great. Turns out there was a cd to through in the drive, follow a few instructions and click fix - the windows XP CD - it was fun to learn linux, but I will be glad to leave it behind for now - thanks.
