Wipe Disk - Help

plumberg

Hi, I am letting go a KS server... How can I securely wipe the disk before transfer?

Is this good enough? https://www.looklinux.com/how-to-wipe-hard-drive-clean-using-dd-command-in-linux/

Thanks!

Just reinstall OS and wait until it finishes before proceeding with transfer if you have no previous experience with this and you have sensitive data into it.
Best regards, Florin.

Yeah. Fresh reinstall with only one partition, install tmux and fill it with zeros. Or boot from a live system and dd the whole device.

I just leave stuff on the disks, fuck it, what's the odd your server ends up in the hands of someone who can be arsed trying to recover old data. Within a day it's chock full of the latest linux ISOs anyway.

boot into rescue, run via 'screen':

openssl enc -aes-256-ctr -pass pass:"$(dd if=/dev/urandom bs=128 count=1 < /dev/null | base64)" -nosalt </dev/zero | dd of=/dev/sda

add another screen for sdb, sdc, etc. if there is more than one disk.

edit: if it is spinning rust, this obviously will take a while. hence the screen session. once tabbed out it should continue running, so you can logoff and forget about it...

Will definitely check this screen... never tried this. Thanks!

This is the reason why OVH disks are old age.

Plus you get insurance to buy new drives.
