Scrub Disks

[Nobody's Hero]

I have to scrub a lot of Jamaica drives. Like 100 or so.

Is there a script available that will do something like an ioscan and remove the data for every device?

Or a dd script available ?
I remember destructive data blocks as an alternative but I dont remember how to do it.

Use dd with the device special file /dev/zero as input i.e.

# dd =if=/dev/zero of=/dev/dsk/c#t#d# bs=1024k

How about the OS disks?

Hi,
did you find this earlier thread:

The same technique can be used for the OS disks. Do them last and at some point the box will crash but enough data will have been clobbered that it will suffice for all but the most rigorous security demands. For those, the best solution is a hammer.
