Cpy%Sync column - high disk activity after reboots

Hi

Cache is always flushing it's content to disk - so if you have the 'writeback' variant and there were some unwritten data which sits only in cache, they are automatically pushed to origin (cached) device - which is likely your disk activity.

I'm sorry if I was unclear. But I'm not using writeback mode yet. The period of disk activity after reboots occurs with writethrough mode.
