I would like to completely wipe all partitions and the master boot record and to make sure that the disk is zeroed out. I was looking around and see different variations of the dd command.
1. Is this the correct command to run?
Code:
sudo dd if=/dev/zero of=/dev/sda bs=1M
2. Will this erase the Master Boot Record?
3. What does each part of the command mean?
4. Would this command erase all of the drives on the PC?
Code:
sudo dd if=/dev/zero of=/dev/ bs=1M
Thanks!
