Thanks for the tips.
1) Is "–d unwritten=0" option is pretty safe?
2) What's the recommended value of "-d agcount=" for?:
10GB disk for web/mail/streaming server accordingly
50GB disk for web/mail/streaming server accordingly
300GB disk for web/mail/streaming server accordingly
Or how can I calculate these recommended values?
