What about using dd to zero the partitoins first. Think that might help?
What can I do to make dd zero a drive quickly?
I will try this.
dd if=/dev/zero of=/dev/hda5 bs=4096

Roy, You may want to check to see if there are differences between Debian and Mandrake in /proc/sys/dev/raid/speed_limit_max If so, wind it up a little tighter using: echo -n 500000 > /proc/sys/dev/raid/speed_limit_max Hope that helps, Curtis _______________________________________________ clug-talk mailing list [email protected] http://clug.ca/mailman/listinfo/clug-talk_clug.ca Mailing List Guidelines (http://clug.ca/ml_guidelines.php) **Please remove these lines when replying
