Hi all,

sorry, if this has been asked before. But,

I am now working with some Raspberries for around one year, and now I am
confused about the following:

I can download NOOBS 1.4.x as a zip ball, and on a Linux machine, it is
always easy to install the image on a brandnew SD card. These cards are
always formatted with MS DOS VFAT32, and you just have to mount the
relevant partition, cd to where it is mounted, and extract the whole
content of the zip archive to it.

After that you can put the SD card into the Rapsberry, boot from it and
run the setup procedure.

Not so, if you take a used SD card and format it to again have a VFAT32
filesystem on it
( I do something like "mkdosfs -F 32 /dev/sdb1" ).

A card which you have formatted this way can be used in any MP3 player or
camera, but when trying to boot your Raspberry from this card, this
attempt will always fail.

So, there seems to be something different. I just don't know, what
exactly is missing when formatting a used card.

Does there have to be an "MS DOS master boot record" written to it?

I know that those cards can be purchased "ready-to-use", but I'd like to
understand, what's going on here.

Thanks for info,
best regards,

Markus
