Zero is a bloc device, not a directory. The command should be :

sudo dd if=/dev/zero of=/dev/rdisk0s3 bs=1m count=100

no slash after zero.

same prob, not a directory..
I looked it up and disk was labeled disk0s3, not rdisk0s3
do you need to set it to /dev/zero/ or /dev/zero ?
thanks in advance

Have you correctly enter the “of” disk. Are you sure it is labeled /dev/rdisk0s3? To know that, you can go to the Disk Utility (Applications-Utilies) and look for a partition under your MBP hard drive (if you’re using a MBP of course…)
