- Reference: SSD precondition
Fill SSD with sequential data twice of it's capacity. This will gurantee all available memory is filled with a data including factory provisioned area:
$ sudo dd if=/dev/zero of=/dev/**deviceID** bs=1024k
$ sudo dd if=/dev/zero of=/dev/**deviceID** bs=1024k
dd will finish with the message No space left on device
or an out of space error
. This shows that dd has successfully completed writing to the entire disk and there is no more space left for dd to continue.
