What transfer cable did you use?
My PC is acting as if it will read the first time and first time only... as if upon communicating with my Xbox harddrive, something is being left behind on the PC which hinders it from seeing the drive.
I say this because the initial use worked on the first plug in and then stopped.
After factory reset of PC (could not find the left behind file) it worked upon first plug in and upon selecting the Partition 3 immediately stopped communicating.
Pisses.me.off. In the meantime I'm in 2009 of my franchise... only a few years til I'm back too reality. Only, Tom Brady plays for Detroit in this new reality.
