Properly Wiping A Drive

[Westyfield2]

I want to securely (write blanks etc.) to a drive but then still be able to refromat it and use as if it were brand new. (So not the smack it with a sledgehammer option). And it want to do this via a floppy @ bootup.

I've read of KillDisk & DBAN both of which are available free, but Killdisk also has a pay version (which I'm not interested in).

I've assumed that these two are the best of the free ones, so which one is best?

TY

Just done some more reading and DBAN seems the better of the two.
Anyone know what it's like with SATA drives?

Moreless decieded on DBAN, but which method should be used:

What's the most secure?
I'm guessing that it's DoD 5220.22-M

 

[Westyfield2]

Just read that the Gutmann Wipe does it 35 times so is that more secure?

EDIT But now just seen this so DoD 5220-22.M should suffice...

Got a DoD 5220-22.M going; How long is it gona take on my 300gb maxtor?
It's been going 3hrs and says 20% - but then says 15hrs to go (or is it 15hrs total?)

If you want an proper wipe then it's going to take a while.Leave it over night.

Did just that, DoD 5220-22.M through DBAN took 15hrs on a 300gb Maxtor but only 3hrs on a 74gb WD raptor.

I recently did a 5220-22.M on my 160Gb Samsung P80 and it took around 8-9hrs.

I used dban from the ultimate boot cd available at http://www.ultimatebootcd.com It has lots of HD manufacturers diagnostic utils and a selection of drive wiping apps inc dban and killdisk. One of the most useful utils I've come across.

is this basically a low level format which replaces all the sectors with 1 or 0 (i cant remember) so no data can be recovered?

i used Peter Gutmann's algorithm last time i had to wipe a drive. A whopping 35 passes, with 27 random-order passes using specific patterns combined with eight passes using random patterns, took me about 9 hours on 40 gig hd Disk Wiper by paragron is good software.
