Using a terminal, such as crosh .sh script?

[king1]

the only chromebook i have pulled apart had a screw as the write protection iirc, it would depend on the connector you have I think there are different sizes and spacings, mostly on windows based at least they are all the same...

you could try this - crosh seems to be the equivalent of a termininal or command prompt
