No, DBAN is basically a custom Linux system. Like WinNT, Linux cannot use BIOS INT13 disk services, which are real-mode only. If there's a Linux driver for the FC HBA, and the DBAN people build that driver into their kernel, then DBAN will work. Otherwise, DBAN won't even see the disk as present. > Another option is to use a UBCD4WIN CD ... Another another option is some other Linux boot CD which does include FC HBA drivers (or lets you load them). Then you can use any of several commands to do various overwrite patterns. "dd if=/dev/zero of=/dev/whatever" will fill a device with zeros. "badblocks -w" will fill the disk with 0xAA, 0x55, 0xFF, and 0x00, in successive passes, which is probably as good an overwrite as any other on modern disks. "badblocks -s -v -w" gives you a progress indication. "shred" can fill a disk with various patterns and random noise, in random orders. "shred -v" gives you a progress indication. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
