Trying to recover a crashed disk....

I was under the impression that using LVM tools like 'pvscan' and
'lvscan' could find the LVM partitions, if you could get past the first
few sectors/cylinders of the disk. That is the volume groups info was
'out there' regardless of the tables manipulated by fdisk.


PV label is located withing first 4K on device (whole disk or
partition), usually second sector. If partition table was corrupted, PV
will not be found. You could search the whole disk for PV label header
LABELONE.

I'm having trouble doing the latter, outer cylinder may be corrupted.

Ideas?
