I am not very experienced using Linux and I have the following situation that cause me some doubts.
I have wrote RaspBian (the RaspBerry linux distribution) on an SD card using this command on Ubuntu:
sudo dd if=2014-01-07-wheezy-raspbian.img of=/dev/sdb bs=1024
So if now I run the
fdisk -l command I obtain that I have 2 partitions on my SD card:
Dispositivo Boot Start End Blocks Id System /dev/sdb1 8192 122879 57344 c W95 FAT32 (LBA) /dev/sdb2 122880 5785599 2831360 83 Linux
And now the first doubt: the dd command creates two partitions on the SD card:
- /dev/sdb1 that is a litle FAT32 partition (what it means (LBA)?)
- /dev/sdb2 that is a larger Linux ext3 partition
The question is: why it also creates a FAT32 partition and not only a Linux ext3 partition?
If I go into my computer resource I can see a device (related to my SD card) into the devices list that contains some RaspBian file, following a screenshot:
And if I see the property of this device I obtain this:
So, looking at the previous screenshot it seems to me that this is the small FAT32 partition, and now I have the followings doubts:
If it is the smallest FAT32 partition, what contains? The RaspBian boot or what?
Why, in the devices list, I have only the FAT32 partition and not also the Linux one (/dev/sdb2), to see it have I to mount it? How?
