Years ago I upgrades my Series 1, I think I put in 160 or 200gb hard drives. Of course only 137gb was recognized.
Is it now possible for me to update the kernel and access the previously inaccessible space?
If it is possible, will I lose existing recordings, season passes, etc?
Finally, if it is possible, how do I do it?
Thanks in advance
Its is possible; there are a variety of methods; the easiest way is using InstantCake. The more difficult ways, including ones that will allow you to preserve your existing recordings, involves DIY methods discussed at places like tivocommunity.com.
