Xbox – Do I lose the achievements if I recover the Gamertag

Ok, if you are not connected to xbox live when you earn an achievement that achievement is stored on your local box.

If you then go and recover your gamer tag to a new box, the new box (and live.xbox.com) won't show those achievements. To have your achievements unified across all media you need to sign the box that earned them back into xbox live on that account.

Recovering your gamertag is a special processes where your gamertag is transfered to a new box and retroactively removed from all other boxes. Because you removed it from his old xbox before updating that achievements, you necessarily lost your ability to update those achievement.

I'm sorry, but you should always connect to xbox live whenever possible if you want to maintain your achievements. God forbid your box red rings and you lose all your work.

As long as you sign in with the same Live account, your achievements will be visible on both sides of the fence. That is, when playing a Games for Windows Live game, you will be able to view all achievements in all games for both platforms.

However: The Xbox 360 and GfW-Live versions count as separate games, even though they will have the same title. So, if you play Fallout 3 on both the PC and the 360, they will not share achievements. Yes, this also means that you can earn a total of 2000 gamerscore by earning all of the achievements on both platforms.
