Hi Gert,

I'll try what you suggest tomorrow. It is all very strange since my last
email another of the 4 disks now has the same error. I am that unlucky
that 2 disks fail? 

When the machine boots the SCSI bios says:

ASYN start unit request failed

It does seem to be spinning.I can hear it and if I rotate it I can feel
the centrifugal force from the disks spinning inside.

If i boot with my linux boot disk it sees the drives sda sdb and the two
partitions on each but it says 

"sda spinning up disk....................." 

and ultimately fails It can also identify the vendor and model number on
the linux boot.

I'll take this to another list but its just interesting so I thought I
would post (I'd still like some advice for my original question though
regarding rebuilding from what is now 2 disks of 4 in my LVM)
