I think geom class will be more useful for this (predictable results) maybe I should try writing one sometime. I my case I suspect power supply, as it's stoch 400W which came with the chassis, and maybe (/very likely) it doesn't support enough current on +12V line for 7 hdds. > The old sectors are not freed if they are referenced by snapshots or > clones.
