It would probably be more appropriate to use a smaller block size and a larger count, since all the larger blocksize is achieving is wasting huge amounts of ram during the process.

Doesn’t filling files with zeros make them sparse? It would be pointless to test disk with sparse files.

No real reason, I guess. At the time my fear was that only zeroes wouldn’t trigger an error, if there was some sort of limit to the drive. Now that seems silly though.

Is there any particular reason you use random gibberish? I wanted to fill a disk the other day and simply used dd to create multiple files from /dev/zero.
