* NT- Nook Tablet, * OF- Original firmware (B&N version of Gingerbread)

I have a rooted OF NT8GB with the following issue

missing SDCard when Nook Tablet 8gb connects to my Acer C7 chromebook running ChrUbuntu
so I see the 4GB internal data partition of the Nook Tablet 8gb but there is no hint of the external SD Card


I really only keep stuff on the SD card because we all know the internal partition can be wiped out and reset by the device

lsusb will list the NT8GB but not the external SD card

I certainly do not want to eject the SD card from the tablet

Note: when I connect the Nook Tablet 8gb to my other WIN7 Acer Laptop i see both the Nook tablet and the external SD card in the tablet
as 2 separate drives with 100% success

I really want to resolve this so I can switch over to Ubuntu completely
I do not plan on replacing nook firmware;


TIA
Dave
