Shortly after TiVo announced the TiVoHD, 3rd party TiVo upgraders like DVRUpgrade and WeaKnees began taking preorders for upgraded units with larger hard drives. The stock unit has a 160GB hard drive, which is just large enough to store 20 hours of HD content.

There's just one problem. It turns out the MFS Tools software that has been allowing users to upgrade TiVo drives for years doesn't work with the new box. That's because TiVo made a slight change to the file system, which apparently could enable hard drives larger than 2TB. It's not clear whether that means you could slap a 3TB drive into a TiVoHD right now (assuming one existed), but support may be enabled in the future.

Anyway, it looks like a member of the TiVo hacking community has been hard at work developing a new tool called WinMFS that allows you to prep an upgraded hard drive using Windows. Previous tools required a Linux box. Anyway, he's managed to throw a 500GB hard drive into a TiVoHD, and plans to publicly release WinMFS soon, which means you may be able to upgrade your box by the time it arrives. Or order one from a 3rd party retailer.
