Re: [gentoo-user] Preserving the initial partionin/formatting of an usbstick

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
