Hi Ia, thanks for your reply ! :)
The usbstick I want to make an initial backup is 64GB of size. That means, I will backup mostly zeroes. Where are the partioning/format defining on the device? If there are only stored the beginning of the device: How much do I need to copy? or: If there are tools to extract all needed informations of the partioning/formatting and to recreate exactly that kind of partitioning/formatting later with that or other tools: Which tools do I need and how to use them? Thank you very much in advance for any help! Best regards, Meino Ian Bloss <ianlin...@gmail.com> [16-03-29 18:12]: > If you're gonna dd a drive you either go the same space or larger.
