Yes. The good news is all my data is safe on:
- the original location of MacHD (currently not installed in the Mac)
- the new location of HD1
- the TM drive of BKUP_TM
Might it be a good idea for me to do this?
1. Manually delete any directories on BKUP_TM that are after the change from MacHD to HD1
2. Reinstall MacHD and remove HD1
3. Boot from MacHD
4. Mount BKUP_TM so that it will see MacHD and reassociate itself with MacHD
5. Reinstall HD1 and reformat it
6. Remove MacHD
7. Boot from OS DVD
8. Use Time Machine to restore from backup (on BKUP_TM) or use Migration Assistant to populate HD1.
This idea has flaws (would step 4 work??) and is a lot of steps and time, but it *might* get me back to a usable TM history.
I should note this: NO work has been done on this computer since I first introduced HD1. This means that I will lose NO data if I go back to MacHD as my system drive and use it as the new starting point.
That's just my idea. All ideas are welcome.
steve, Read this as well as peruse the Pondini info previously sent. I am not a TM expert (I don't even play one on TV) and would not want to guess with your data and make an error that could cause you problems. As opposed to guessing the proceedure I would suggest to follow any of the aforementioned, as TM is an entity unto itself. I hope this helps
I appreciate your help and your attention to keeping my data secure.
Deeper reading of the Pondini site has led me to this course of action:
1. Update OS from 10.6.8 to 10.8.3 (required in order to use the tmutil command that is part of the next step)
2. Follow the Pondini instructions here for "reconnecting to your backups"
3. (hopefully) live happily ever after
I was hoping to not update the OS (I still use one or two appsthat require Rosetta) but maybe this isthe kick in the pants I need to find other solutions for those apps.
If this new plan goes poorly, I still have my original MacHD on the shelf and can go back to it.
I'll update this post later to include the final outcome.
If you have all the data on your internal drive that is on your TM B/U you can erase the the B/U drive and start as a new TM b/u.

Thanks for the help. You pointing me to the Pondini site was the thing that led to my solution. I checked my Apr 26, 2013 11:08 AM post as the "this solved my question" item because it holds the steps that were the end solution. I would not have gotten there without your help, though.
And... if I'd done things "your way" from the start, I wouldn't have had any problems along the way.
"Replaced Hard drive in my Macbook Pro but Time Machine archive is now not available" - Thank you very much for posting this. I just followed the ifixit steps to swapping my MBP HDD with an SSD using CCC to clone the old HDD drive to the new SSD whilst I was doing a battery change. All went to plan until once booted up, I checked my Time Machine only to see all my history had vanished. Luckily before dispair dropped in, the above google question took me straight to this Apple Discussion and with a link to the very clearly written Pondini site and a bit of simple keyboard action in Terminal, reconnected my new drive back to the time machine archive created by my old drive. I will make sure this post is brought to the attention if ifixit as if had it been included, the resulting sudden increase in heart rate would have been avoided
