# How to Create an Official PicoCalc SD Card  

The purpose of this wiki is to document the partitioning and creation process of the official PicoCalc SD card.

## Script  

```bash
#!/bin/bash

DEVICE="/dev/$1"

if [ -z "$DEVICE" ]; then
  echo "No disk"
  exit 1

What is the max size of card the PicoCalc will take successfully ?, I have a spare 256Gb and would prefer using that to buying another. The above official Wiki example seems to be using a 64Gb card.

Anyone tested SD card speeds with Pico and Pico2 etc ?

Formatting seems a little messy and I dont have linux available. It seems there’s a need for a one-click Windows app just for this purpose unless one already exists ?.

You can use any size card ≥ 32 GB you want but only the first 32 Gb will be used, according to the format routine you cite.
