Is it necessary to create a "partitioning standard" for a usb, usb card-reader, or hard drive?
What benefit does it offer?
I created a partitioning standard for my usb card-reader and ran into difficulties and eventually had to change from 'gpt' to 'msdos', though it is for use solely on linux.
I imagine if I do not create a partitioning standard, the micro-sd in the usb reader is likely set to msdos by default. In the past when I formatted it to 'ext4', the sd didn't allow me to add files to it in linux os; maybe this is why.
UPDATE: I read the following info, which is what led to this question, in addition to what I wrote above.
"Partition the new drive. We'll create a single partition using entire disk. CHOOSE A PARTITIONING STANDARD: To do this, we first need to specify the partitioning standard to use. GPT is the more modern partitioning standard, while the MBR standard offers wider support among operating systems. If you do not have any special requirements, it is probably better to use GPT at this point. To choose the GPT standard, do: "sudo parted /dev/sda mklabel gpt"; To choose msdos: "sudo parted /dev/sda mklabel msdos"
