    It won't cause a problem for Time Machine, as it keeps track of drives/partitions by their UUIDs, not their names.

     

    If you don't delete the old backups, though, it may cause you a problem, in looking at the backups, if you forget which ones are which. 

     

    As now, the backups of the original drive are named "Library HD" on the early backups;  on subsequent ones, they're "Library HD 1" and the replacement is "Library HD."

     

    If you disconnect the first replacement and start backing-up the second replacement, the first replacement's backups on earlier backups will probably be called "Library HD 2," and the second replacement will be "Library HD."

     

    There's nothing you can do about that on Snow Leopard;  on Lion, if you're careful, you can "associate" the backups of both old drives with the new replacement, so they're all called "Library HD."

     

     

    And, that's not going to save a great deal of space on your backup drive:

     

    • If you upgrade to Lion and do the "associatedisk" before starting to back up the second replacement, you'll still have two full backups (of the original and the first replacement), plus incrementals.

     

    • If you start backing-up the second replacement before doing the "associatedisk," you'll have three full backups -- the original and both replacements.

    Cool. 

     

    So, did the restore to the second replacement drive work properly?  Or is it not done yet?
