In the process of replacing the drives in a TiVo S2 with new WD GP 1TB dirves, I managed to mess up the new drives. (I think it was because I did not add -r4 when doing the mfsadd.) I have tried using WinMFS, but it does not show my drives even though they show up in Drive Manager (No I did not init them in drive manager.) Mfsinfo also throws a ton of errors. I tried pdisk, to delete partitions, but it does not seem to work. So my guess is the drives are messed up.

How can I reset the drives and start over? Or is there some other way to fix the drives?

Thanks!
