I have just flashed my N900 with eMMC and them FIASCO aka COMBINED. I left Micro SD card in the phone while flashing.

I have done numerous re-starts but my phone doesn't see/mount external SD card which was working before flashing.

Phone's File Manger doesn't see the memory card.

On Windows 7 PC, I check the Micro SD Card with USB Card Reader and although it shows Device Detected etc but it is in accessible.

Is my card corrupted? What can I do to check it.
I also have a PC with Ubuntu 12.04 64-bit if it can be used to mount/test.

Please help me as I had all my data backed up on Micro SD card and without it I will lose all my data.

Kind Regards
