I've been out of touch with the upgrade community ever since getting my S3. However, now that the drive is failing and it's out of warranty, looks like I'm being thrust headlong back in. I'm fairly sure I have a lead on an image to use (since I dind't make one, more fool me) but I'm rather confused about this WinMFS utility that seems to be recommended. Back when I was involved in upgrades with my ancient s1 and its following s2, there was one piece of advice that was always, always made - never boot windows with a tivo drive attached, it will ruin the tivo drive. Yet, WinMFS runs in Windows. Is this really safe to boot Windows XP with a sata tivo drive attached? Also, WinMFS's site strongly recommends against using WinMFS with XP (original release) and recommends XP SP2, without a mention of SP1. The only computer I have available right now runs only XP SP1, and certain applications I must run for work don't run under SP2 so upgrading is not an option. Is WinMFS safe to use under XP/SP1?
