==<font color="blue">About</font>==
Help tips for formatting:
* SSD (internal or external)
* MMC (&muSD card - normal or recovery)
* USB drive

Can be done either from the camera or PC, the required programs are:
* '''fdisk''' - format into partitions
* '''mkfs.ext4''' - create filesystem
* '''mkfs.vfat''' - create filesystem
* '''dd''' - clean filesystem from the partition for '''fast recording'''



==<font color="blue">SSD or USB</font>==
===camera===
* (not needed for USB) Check if SSD is connected to the camera:
** The default connection is ''camera <=> internal SSD''
** For external drive set: ''camera <=> external SSD'' and power on the drive.
** [[Sata_multiplexer_10389| '''More info''']]
* Find out the device name:
$ dmesg
* Check if it is already partitioned:
$ cat /proc/partitions
* manage partitions:
$ fdisk /dev/sda
* format a partition for file storage:
$ mkfs.ext4 /dev/sda1
* for '''fast recording'''
** Do not make a file system on the partition

===pc===
The same as above except:
* For internal SSD the connection should be set to ''pc <=> internal SSD''

==<font color="blue">MMC</font>==
===camera===
Make sure the camera is not boot from the MMC - in MMC boot by default the camera gets the boot files from /dev/mmcblk0p1 (FAT32) and
mounts /dev/mmcblk0p2 (EXT4) as /.
* check boot mode:
$ mount | grep " / "
* check existing paritions:
$ cat /proc/partitions
* manage partitions:
$ fdisk /dev/mmcblk0
* format a partition for file storage:
mkfs.ext4 /dev/mmcblk0pX

===pc===
* Same as above except the MMC might be detected as /dev/sdX
* If MMC is for boot the partition table type must be '''msdos''', not gpt



==<font color="blue">'Erase' a file system from a partition</font>==
Sometimes there is a need to this:
* if the drive was partitioned several times and the old file system journal starts from a location of a new partition - the file system will surely show up.
* by accident

Examples:
* Use '''dd''':
** 'Erase' a filesystem from /dev/sda1
$ dd if=/dev/zero of=/dev/sda bs=1MB count=1 seek=1
* 'Erase' a filesystem on /dev/sda2, if /dev/sda1 size is ''SIZE'' MB:
$ dd if=/dev/zero of=/dev/sda bs=1MB count=1 seek=SIZE
* To erase the drive's partition table (better use '''fdisk'''):
$ dd if=/dev/zero of=/dev/sda bs=512 count=2



==<font color="blue">Useful links</font>==
* [https://github.com/Elphel/elphel-tools-update github:elphel-tools-update] - '''write_bootable_mmc.py'''
** the script is used to create a bootable MMC from a PC (the camera doesn't have ''parted'' and ''kpartx'' installed)
** it has examples of using '''dd''', '''parted''', '''mkfs''', '''kpartx'''
* [[Sd_boot_rootfs|MMC boot]]
** prepare a bootable &mu;SD card and boot
