I need to wipe out some AIX hard disks so that I can make them
available to the public. I do not want the average hacker to be able
to get to any data. I've thought about writing a script that will
fill a file system with a big file full of 1's then delete it and
start over. Lets say the file system is the same size as the disk,
73gb and I write this 73 gb file on it three times. Should that keep
the average hacker from getting to any data that used to be there?
Thank you in advance for your replies.

Use diag, and just do a "format" and "certify". That is usually
sufficient for most applications.
