Thanks for post 46.

I bought a 2G mini SD card for backup. From the terminal I

cp -R /media/mmc2/folder_name /media/mmc1

for each folder in mmc2. I then used the usb cord to upload these to my mac. After this I could not see either mmc1 or mmc2 on my mac.

I did steps 8,1,..6,9 and was able to restore files to mmc2.

I can use mmc2 (save email enclosures etc) but cannot see it when plugging in the usb. For now I will use sftp for file transfer -- until this gets sorted out.

Thanks to all for helping out in this.
