Tested by `time dd if=/dev/{s|h}hda7 of=/dev/null bs=1M`, about 4.5GB of data. -jkt -- cd /local/pub && more beer > /dev/mouth ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
