I have a bootable Fedora 64 GB flash drive. I use it
to troubleshoot customers' computers -- mostly Windows.
Windows loved to eat these sticks. (I have had great
luck switching to a Samsung stick.)
I have previously used dd to backup these sticks and
reverse dd when they go corrupted. But this one is on
the large side. So I was looking for some compression
The point of Eyal's method is to ensure that all the free space on the
drive is filled with zeroes, thus improving the compression. Otherwise
you are just uselessly compressing junk.
