Greetings,=20

Had a Mirrored Drive slightly unclipped for a few days. SLES 9 AMD64
It blew the controller, and syncronized the bad blocks... the sda2
partition became unmountable.

I have tried all of the reiserfsck options, with no luck. even the
badblocks file.
Always failing on 8210...=20

I have dd_rhelp the partition to an external usb partition.
and have dd the partition of a another (sdc2) for diagnostics.
debugreiserfs -B bb.txt /dev/sdc2
states no bad blocks in the copy of the partition
but that is also unmountable and the reiserfsck --rebuild-tree says:
bread: End of file, cannot read the block (17384335).

I believe that the partition is unrecognized as a reiserfs.

How do I recreate the header to specify the filesystem type?

>felix:/mnt # dd if=3D/mnt/disk.dump of=3Dtempfile bs=3D1024 count=3D1
>felix:/mnt # mount -t reiserfs -o loop tempfile /mnt/recover

I'd compiling the Coroners Toolkit now...

Thanks
