I have an alphaserver 4100 with a rack of attached disks,
which our site regulations dictate I must clean the disks of before
I turn over to excess.
I am booted under single user mode at the moment, using
dd if=/dev/zero of=/dev/rzxxc bs=512 seek=1
Have done two of six of these disks so far, but it is taking >12 hours
for something that's only an 18Gb disk.
Any way to do it faster?
Also, once I get all the scratch disks wiped, what's the easiest way to
wipe / and /usr? boot off CD? Or can I use the existing OS install
to wipe the disk from under me, dying in a glorious panic when the dd
command returns?
Steve
