If you use WinMFS, this will allow you to use more of the 1.5TB drive on an original Series 3 (TCD648). I have done this and have been able to use 1.35TB of the drive for use in the TiVo. There is a 1TiB size limit on TiVo partitions, which equates to about 1.1TB. And since the original drive is 250GB, you get 1.1TB + 250GB = 1.35TB.
If you have Windows and WinMFS, making backups and restoring to new drives is extremely easy. You can use external eSATA enclosures, USB to PATA or USB to SATA converters, or directly connecting the drives internally on the drive bus. I've done all of these and I have a dedicated computer for drive upgrades and backups. It runs Windows XP, so I don't have to remember to run the program in Administrator mode every time.
The MFSLive Boot CD will not let you use more than 1TB for use with any TiVo. This is a function of the current build.
Hope this helps,
