gregor can help once you find it out.

we need a function thatreturns the size of an sd card given the device

[laszewsk]

do we have a diffenet command that gets only one number?

[laszewsk]

so we can use what we have and use or we just use info and parse the first value split by space and multiply by 1000**3

fix field names looks liek that the split of the info has wrong order. there may need to be other fileds. create as much info as possible, and compare to the result of info posted next from linux
