Discussion heretheom wrote:'Disk drive is empty' means that the RISC OS partition on your SD card can't be detected. This either means you didn't write the SD card right, or RISC OS doesn't like your SD card, or you have power supply problems.
To see if RISC OS can at least find your SD card, press F12 and type
and see if anything is listed.
If your SD card is OK but badly written, it should show up. If RISC OS can't talk to it at all, it'll report no cards
It should be pointed out, once again, that this whole "It shrunk my card! It's only 32M!" idea is completely bogus. It has nothing to do with anything in the Linux world or the Linux side of things. It is merely an artifact of Windows. Repeat: It has nothing to do with anything relevant to the Pi; it is only when you load the SD card onto a machine running that other OS that you see this effect.Only when I ran that did I realise that the card appeared to have only 32 MB, not the 16GB I paid for! The formatter fixed that when I had selected FULL format.
