Re: Recover a XFS on raid -1 (linear) when one disk is broken

I have tried this two times now and after about four hours the computer 
crashes with this in /var/log/messages :
 [...]
 Jul 30 20:46:23 d kernel: hdh: dma_intr: status=0x51 { DriveReady 
SeekComplete Error }
 Jul 30 20:46:23 d kernel: hdh: dma_intr: error=0x01 { AddrMarkNotFound 
}, LBAsect=28117754, high=1, low=11340538, sector=28117718
 Jul 30 20:46:23 d kernel: hdg: DMA disabled
 Jul 30 20:46:23 d kernel: hdh: DMA disabled
 Jul 30 20:46:23 d kernel: PDC202XX: Secondary channel reset.
 Jul 30 20:46:23 d kernel: ide3: reset: success

Second time the last sector mentioned was 28117656. Maybe I should try 
to skip over that and start right after that sector? If I read the 
man-page of "dd" right I should add something like "seek=28117718 
skip=28117718" to that command-line to perform that. Am I correct? What 
you think?

Thanks alot for your input,
Jan
