If you're gonna dd a drive you either go the same space or larger. To be sure you get everything you can just
dd if=/dev/oldstick of=/dev/newstick Replacing old/newstick with the correct device. You can even keep a backup image with dd if=/dev/oldstick of=/home/user/whateveryounamedit.img Which you then can replicate to any drive dd if=/home/user/whateveryounamedit.img of=/dev/newdevice On Tue, Mar 29, 2016, 11:43 <meino.cra...@gmx.de> wrote: > Hi, > > since companies know their usbstick internals best, they > format their drives in a way, that the performance is best. > > That's why I want to make a complete image "backup" of my > new usbstick first before using it in case of needing to > reset the whole thing. > > The stick is a 64GB vfat formatted device. > > How much of the usbstick do I need to dd/pv from > the stick to preserve *all* informations to do a > "true factory reset" later if needed? > > Thank you very much in advance for any help! > Best regards, > Meino > > > > > >
