the data cable could have come loose...might want to take it apart if you know what you are doing.
I thought of that. Looked under the inspection plate for the ram and could see that the drive plugs into a fitting that appeared to be directly soldered on the circuit bourd. Do you know anything about filters? SD\MMC took its place and drive letter in device mgr. and my computer. I uninstall it but didnt do anything to bring the drive back. Do you think im on the right track?
