When copying partitions or whole disks, I usually use larger buffers like bs=128M or bs=1G. The problem arises if one of the physical input blocks is corrupt, then the whole output block might be padded with Zeros.
and without notice :-(
That's why ddrescue (or dd_rescue) are more specialized in such a failing disk case: they copy with adaptive block sizes, trying to rescue as much data as possible around the failing blocks. For healthy disks, dd(1) perfectly fits my needs though.
but who know if a disk is healthy sector copy is only good for cloning, that is duplicating indentical disks in a number jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
