Hi

I got 2 raid arrays, both raid0.
=46or some weeks the raid array md0 have had errors, indicating one of =
the=20
disks where gonna die, so i jused the array as an temp partition untill=
=20
the array died.
Today was the day, but somethign else seem to have happend.
The other raid array is also broke now, and i can't get it it working=20
again, so im looking for suggestion for how to get it back and working=20
again.(this array is fully working and the disks are new)

Heres the info on the raid arrays, fetched from raidtab

raiddev /dev/md0
        raid-level      0
        nr-raid-disks   2
        persistent-superblock 1
        chunk-size     4
        device          /dev/hde
        raid-disk       0
        device          /dev/hdh
        raid-disk       1

raiddev /dev/md1
        raid-level      0
        nr-raid-disks   2
        persistent-superblock 1
        chunk-size     4
        device          /dev/hdf
        raid-disk       0
        device          /dev/hdg
        raid-disk       1


The array md0 is the array with a broken disk,
MD1 is the array that is suposed to be working, never had any errors on=
=20
it, the disks are relativly new.

Here is the error code, fetched from dmesg
