Disk partitioning

parted

when creating a partition, you should prefer to specify units of bytes (“B”), sectors (“s”), or IEC binary units like “MiB”, but not “MB”, “GB”, etc.

Script mode:

sudo parted --script /dev/sdX COMMAND

Or interactively:

sudo parted /dev/sdX

Use GPT as partition table:

mklabel gpt

Or for sdcards/compability with legacy devices:

mklabel msdos

Create partition (GPT):

mkpart "data partition" ext4 0% 100%
mkpart "ventoy" ext4 0% 64GiB
mkpart "data" ext4 64GiB 100%
quit

Then format the disk:

sudo mkfs.ext4 -m0 -L usbstick /dev/sdX1

or for vfat:

sudo mkfs.vfat -n fotos /dev/mmcblk0p1

Create a new single patition on i.e. a usb drive and format it with FAT32:

sudo parted -s /dev/sdX -- mklabel msdos mkpart primary fat32 2048s -1s
sudo mkfs.vfat -F 32 /dev/sdX1
