I know it’s been a month, but in case this is still an issue for the OP, I might have something to suggest.
I’ve never looked into doing this with a manufacturer utility, so maybe that’s the way to go.
I tried DBAN once (on a single drive), but found it’s just unacceptably slow. I think it doesn’t use any DMA, perhaps out of overkill paranoia, causing it to take forever. I’m afraid this may discourage people from using it at all, and resort to destroying working drives.
I don’t know if you’re comfortable with a UNIX/Linux command line environment, but in case you are:
I found wiping a drive was much faster by booting a live linux CD (knoppix, or whatever you like) and using the ‘dd’ command. There’s also nothing to stop you from doing it against multiple drives in parallel.
From memory, the line would be something like:
dd if=/dev/zero of=/dev/hda bs=1M &
I could have the syntax wrong. This is a destructive operation so you’d want to double check it.
‘if’ is the infile - the source of data that will be “copied” to the target. In this case, you use ‘dev/zero’ which is a phony “device” that generates an infinite supply of zeroes.
‘of’ is the outfile - the target that you are writing to. Hard disks usually have names like ‘/dev/hda’ or ‘/dev/sda’ but it varies depending on the OS. Subsequent drives would be named ‘/dev/hdb’ ‘/dev/hdc’ etc. I think you can use the ‘fdisk’ command to get a list of the names, but I’m foggy on that.
‘bs’ is the blocksize, ie how many bytes will be written at once. The default is much smaller and will slow down the operation.
If you put the ampersand ‘&’ at the end of the command line, it should put the ‘dd’ operation in the background and immediately return you to the prompt. This way you can then enter another identical command for another drive (/dev/sdb, /dev/sdc etc).
If you know how to write scripts, you could script it to launch simultaneous ‘dd’ wipes against multiple drives with a single script command.
If you aren’t familiar with the ‘dd’ command, then read up on it first. You have to figure out the correct device name for the disks you’re trying to wipe. That command can wipe out the wrong drive if you aren’t careful.
Safest way to do this IMO would be to use a bootable linux CD, and the only writable drives in the system should be the ones you want to wipe out. That way no disasters can happen.
