I wrote a short bash script that tests SD cards with [F3](https://3ds.hacks.guide/f3-(linux).html) to see if they're fake, deletes everything on them, creates a new partition table and one exFAT partition on them.
|
||
|
|
|
||
|
|
Here it is:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
#!/usr/bin/env bash
|
||
|
|
|
||
|
|
set -euox pipefail
|
||
|
|
|
||
|
|
sudo umount --force "$1"1 || true
|
||
|
|
sudo f3probe --destructive --time-ops "$1"
|
||
|
|
sudo parted --script "$1" "mklabel msdos" "mkpart primary ext4 0% 100%"
|
||
|
|
sleep 1
|
||
|
|
sudo mkfs.exfat -n Stavros "$1"1
|
||
|
|
eject "$1"
|
||
|
|
```
|
||
|
|
|
||
|
|
Save it as `formatsd.sh` and run it as `./formatsd.sh /dev/sdX`.
