Get the Ultimate boot disk forWin. Get it here:
http://www.UBCD4Win.com - normally you have to make the CD yourself, but you can also get them pre-configured. Go to the site and look for the address of the guy who makes them. When I got mine (some time ago) he just wanted a blank CD and a postage paid, self-addressed envelope. May have changed by now. It has the SCSI drivers already on it for most popular brands. Perhaps once it is booted, you may be able to repair one of your mirror drives. You should also get a copy of the Ultimate boot CD for DOS as that has the SCSI drivers too so you can boot and check out some stuff with that as well - the same guy that makes the UBCD4Win would burn copies of the DOS one too. Why not go for the trifecta and get Hiren's boot CD too. I DLed my ISO from
http://www.9down.com . There is a link to the DOS CD site from the Win CD site and on the DOS CD site there are links to people or companies that make and/or sell them. I think John Haberle is the guy that made mine - he's still doing it basically for free - you just send the blanks and let him know which ones you want. You can ask in your first message which ones he makes so you can send enough blanks and postage.
Hoping one of those can help get you going.
You know the Win. install disk can also boot and automatically load SCSI drivers for the popular SCSI adapters (or bring in from a diskette if not on the CD). May be able to fix it just using that.
Peter is the SCSI guru around these parts. I think he searches for SCSI threads whenever he stops by.
