time machine won't recognize backup file

I set up a new backup drive at home and backed up to it.


I also have one here at work which I've been using for over a year.


After setting up at home, it won't recognize the old backup. when I go to select that drive it wants me to completely erase it.

However it will do a restore using the old backup files.


Anyone know how to fix this?


thx,

17inch powerbook, Mac OS X (10.6.8)

nothing there seems to address the problem.

My backups are there; I can access them with the Browse function.

But when I click on the icon in the menu bar, the top item says "Time Machine Not configured"

and when I go to select my backup drive it wants to erase the whole thing and start over.


I need to activate the backups that are already there and continue on with them.

Well I just tried to do it like an idiot and it erased my backup drive.



I tried to do this:


Before starting: Log on as an Admin user, and make sure the backups in question are connected to your Mac.

Select them as your backup destination via Time Machine Preferences > Select Disk, but immediately turn Time Machine OFF so a backup won't start.
