http://www.unix.com – Guys can anyone tell how can we do faster disk cloning Below i found in google 1. dd if=/dev/sda of=/dev/sdb bs=4096 conv=noerror,sync So adding "conv=noerror,sync " makes it faster looks against not adding it 2. Enable write cache activated (hdparm -W1 /dev/sda) then run dd .. Is above correct ? Any other ideas ? Thanks! (HowTos)
