[GTALUG] 10TB drive seen as a 2TB drive (twice?)

[Scott Sullivan]

Hi Evan,

As other on the thread have zero'ing in on, it is likely an issue with 
whatever USB/SATA adapter your using. This was a known limitation of 
early chipsets, and I recall the marketing shift to 'supports larger 
then 2TB!'.

I looked at the hardware info you attached, and it doesn't go into 
detail about the usb devices.

Can you send along the output of a 'lsusb' command while your USB/SATA 
adapter is attached? We should be able to back search the chipset based 
on the Vendor/Device IDs.
