So I'm totally confused now.

You said it was 'linear', but the boot log showed 'raid0'.


	You aire absolutely right. Me bad

The drives didn't have a partition table on them, yet it is clear from
the old boot log that the did.  Are you sure they are the same drives,
'cause it doesn't seem like it.

That's the root of my problem...when I moved the disks to the new system the disks showed up as unpartitioned.

You could try hunting for ext3 superblocks on the device.  There might
be an easier way but

 od -x /dev/hdb | grep '^.....60 .... .... .... .... ef53 '

should find them.  Once you have this information we might be able to
make something work.  But I feel the chances are dwindling.



Me too. In any case the data was not that critical, so I will play around a little more before I give up.


	Thank you all for your help:)
