Perhaps. The harddisk is a FreeAgent Seagate, connected via USB. It used to go into sleep mode every 15 minutes and I would often have to restart cwfs - this is probably cause for a lot of damage.

Makes sense. But does this also mean that when time comes for a dump, the data will be duplicated in the WORM? Viz., I'll have two copies of the same file, in different dumps? Thanks, ak
