Hi-ho... On the security end, you should have the data encrypted with good pass-keys in place anyway, so erasing the drive is kinda academic. Just saying. :-) -----Original Message----- From: "Fraser McGlinn" <[email protected]> Sent: Tuesday, 18 August, 2015 13:50 To: [email protected] Subject: Re: [Linux-users] Data security and privacy (Re: PATA drives - 80/40G)

Without any further arguments, this will eventually fill the disk and terminate when running out of space. You can give is a block size "bs=..." and count=... to exactly fill the disk. I definately agree with Criggie on this - You need to be a bit more diligent in wiping your data. I prefer DBAN as well. If its an old drive such as a PATA drive which will have no foreseeable use, i'd probably demantile it and use the platters as coasters too. Also to grab the magnets as a fiddle toy. We should be taking data security seriously since even stuff such as SSH private keys, SSL private keys, DNS DNSSEC keys etc, are definitely sensitive and can be used for years without rolling them to new ones. But at the end of the day, each to their own. I can't force others to take data security seriously.
