I use a program called wipe (forgot where I got it - likely freshmeat). I
usually just use the default settings. But, if memory serves me correctly it
allows commandline parameters for the number of passes over a file.
As for your method, /dev/hda is the whole drive. Linux commands likely would
want partition names to write to. That could explain the failure, though I'm
not inclined to try it just now to see.
