Exactamente,

So you want Klaus keep the VDR multi-volume capability?
When there are soft/hard-ware that its very purpose is to handle 
multiple volumes.

I had an LVM1 linear with ext3, on disk got corrupt and i didn't lose 
all data.
But i think i was lucky in that case.

I vote for drop the support for multi-volume capability in VDR, so that 
Klaus can make progress
in the very core of VDR and people wont get upset when VDR destroy there 
recordings.

take care,
