run dd with progress information

dd is a great tool to overwrite disks quickly (if you want to return them or sell them)¹⁾

Overwrite entire disk, e.g. /dev/sdi with zeroes, for example to sell the disk or send it in (CAREFUL)!

cat /dev/sdi > /dev/null

linux

¹⁾

if you are required, use shred, which overwrites the disk with random data, 25 times by default. But: overwriting once is enough to make the disk unrecoverable by professional data recovery services. If i had a disk with real top secret information, i would first overwrite it with shred and then physically destroy the platter
