Continuing the discussion from [Increase emonSD pre-built SD card to 8GB min](https://community.openenergymonitor.org/t/increase-emonsd-pre-built-sd-card-to-8gb-min/1730/12):

As suggested by @Andy_Taylor in the thread above we have implemented a custom bash prompt on the emonPi which alerts the user if the file-system is in read-only (ro) or read-write(rw) mode from the prompt e.g.

```auto
pi@emonpi(ro):~$ 
pi@emonpi(ro):~$ rpi-rw
Filesystem is unlocked - Write access
type ' rpi-ro ' to lock
pi@emonpi(rw):~$ 

```

_This updated prompt will be rolled out to all existing emonPis via emonPi update. Just run ‘admin \> emonPi Update’ in local Emoncms to pull in the changes_\*
