OK I am trying to completely erase the data of a hard disk so I though I can just do `dd if=/dev/arandom of=/dev/rwd0c` as to my understanding that is the entire hard disk (slice c) of wd0 in 'raw' mode?
But that dd refuse to do it. So now I am doing the same thing but to wd0c instead. Is this any worse? This is the "character device" right? Does that mean dd won't write random bits as low as going to the raw device? This is running off a OpenBSD 4.3 CD, there are no intention to actually destroy the hard disk in any way, just erasing the data off the hard disk so that it can be reused, re-sold, whatever. The data are not some military top secret, but it is interesting to know of what can be done in a home/small office environment when it comes to erasing the hard drive.
