Formatting disks

Martin Wells — Fri, 21 May 2004 07:56:28 GMT

We are about to sell on some old K580 servers and want to format the internal disk so no information is left on them.

What is the best way to make sure no data can be recovered once they are in someone elses hands

Martin,

For non-root disks, you can use dd:

dd if=/dev/zero of=/dev/rdsk/cNtNdN bs=1024k

For the root volumes you can just cd to / and do a "rm -rf *". It's the only time in your admin life that you get to do it, so enjoy!

pvcreate will only erase the PVRA and not the data blocks!
You can also write junkdata to the disk with DD, select a random source, the kernel or so and write it to all the blocks on the disk.
