-====== run dd with progress information ======
+====== Use dd to overwrite disk with zeroes, with progress information ======
 dd is a great tool to overwrite disks quickly to erase all information on it (if you want to return them on warranty or sell them)((if you are required by law or are really paranoid, 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))
 Overwrite entire disk, e.g. /dev/sdX with zeroes, for example to sell the disk or send it in for warranty. Be VERY CAREFUL as overwriting the disk will permamently destroy all data on it.
+CAUTION: Only do this if you know what your are doing. Do this at your own risk!
 . DON'T do this in a hurry
