So my question was, using the enclosure I already have, if I replace its drive with a 1 TB drive, will it work as-is or does it have to be formatted or setup in some special way.
The message seems to have gotten garbled.
As far as I know, the relative sizes of the internal and external aren't the problem.
The problem is using a different size for the internal than it came from the factory with.
The TiVo approved Western Digital external drives are, or were, available in 500GB and 1TB.
A TCD658000, which has a 1TB internal drive when it comes from the factory can use one of those 500GB external drives. Or one of the 1TB ones.
The Series 3 HD, the TCD652160, comes from the factory with a 160GB internal drive and a very short list of Western Digital drive model numbers (all of which are 500GB or 1TB models) to which it refers when someone attaches an external.
If the the raw drive inside the external is not one of the models on the list, it won't accept it.
Neither will its "big brother", the HD XL, the TCD658000, nor any of the Series 4 or Series 5 TiVos.
In addition to that, any of those TiVos I just mentioned won't accept an external if you've replaced the internal drive with a bigger one than the one it came from the factory with.
So an HD can't use a bigger internal than 160GB if you want to use an external with it, but the HD XL can use a 1TB internal with an external.
If you need more storage than the 1TB internal you have, get a 2TB and copy the 1TB to it with WinMFS and then check the 2TB drive with
(which is a command available as part of WinMFS)
and only then expand into the rest of the 2TB with
(which is another command available as part of WinMFS)
I wrote some of the above and then went back and added more stuff so that's why it may seem not in completely logical order, but I'm too lazy to fix it.
