No you can not. Someone asked about this & it does'nt work. You can only do it on a HDD extender. The USB is just for HDD extender.
I haven't heard anyone able to do this as the Software may not allow it.
While some people have said they have got the drive to be viewable on a pc and see the files.. they are encyrpted, and not able to play back.
(pretty much all companies PVRs are the same way, bell, etc. Trust me, my boss just tried )
Also with the rogers units.. when you plug in a drive as an extender... it actually set it up as a STRIPPED drive.. as in were it takes the internal and the external, and the rogers box views it as ONE large drive.
Any recordings, could be have data split being stored on both and internal and external.
no you can not
plugging any device into the usb port, will try to EXTEND the hard drive (if a pvr) over the size of the hard drive and what was plugged in USB.
Moving to another unit, would cause it to re-try to format the drive..
If you want to play back from another box in the house, you can get the whole home PVR setup.
