Thanks for the link. I have used an adapter with my PCs before, but didn't think about trying one with the TiVo. One thing I'm not sure about is the maximum supported single drive capacity. I've seen some mention of the limit being 750GB on the HR10-250.
Is TiVo Desktop now compatible with the old HR10-250 DirectTiVo? Last time I checked, it wasn't, which is why my unit is hacked to offload shows.
Thanks for pointing me in the right direction. I'll have to look into the partition limits. I'd prefer not to offload all shows and restore them, since I haven't had the best luck with that (and probably can't use TiVo Desktop).
Worst case, I may just pick up the closest match size (maybe 500GB) and just do a straight clone without further expansion. I'm mainly interested in getting a longer life out of a new drive, rather than expanding capacity.
That 750GB limit you heard about was probably due to that being the largest PATA/IDE drive made. The adapter thread I linked for you shows two people running 1TB SATA drives in their HR10-250s.
First of all, make sure you aren't using a GigaByte brand motherboard unless you've got a sacrificial hard drive attached as Primary Master for it to create a Host Protected Area on so that it'll be satisfied and won't put any on any other drives.
Here's something I copied from "the site which may not be named"

That's for the original 250GB drive.
When you went from the original 250Gb to the 400, you probably added 2 more MFS partitions, so if you want to keep everything on the 400 you'll have to settle for only using 400GB of a 500 or larger, at least using the MFS Live cd v1.4.
backup -Tao - /dev/hd'x' | restore -s 250 -pi - /dev/hd'y'
where 'x' is the 400 and 'y' is the new 400 or larger drive.
I haven't been playing with WinMFS long enough to know if it can enlarge existing MFS partitions or not. I've got to look into that.
Find the link on what's currently the last page of the adapter thread to the Avolusion adapter on Amazon and get a couple of those (cheap enough to have a spare) and find yourself a good deal on a 500GB or larger SATA drive.
