    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.

    OK, of course.

    Yes, I see.  I could just leave the name of the new disk as it is and live with the fact the old backups are there.  I may bite the bullet and delete all the old backups for this drive to make things less complicated.  If it comes to it I have all the original installers.  Food for thought anyhow.  Many thanks for all your assistance.

    Cool. 

     

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

    Oh, yes it did, inasmuch as it made a folder called 'Library HD' on the new drive (Lib A HD).  I just moved all the content out of that folder to the top level of the drive and deleted the folder.  I haven't had a chance to see if the samlpe libraries will get re-associated with their instruments yet.  Probably not, because of the file path naming.

     

    That is the reason it would be good to rename the new drive 'Library HD' of course.  Just problematic keeping track of the backups in TM then.

     

    So overall this was a more straightforward approach, although it didn't appear to matter whether I 'restored to' from the backup of the original drive in TM, or from the TM drive itself in TM.  I got the same result either way.

     

    I will probably get a chance to check the instruments/libraries out tomorrow afternoon/evening.  That will also give me time to give this a bit more thought.

    Quick update, I renamed the new drive 'Library HD' as per the original drive and every software instrument worked staright away, having found its sample library content, so that's a result.   I will change the name back and check to see how many cannot be pointed to where their libraries are.  That would mean re-installing them which in some cases is a pain on account of the number of discs/time involved and possible authorisation issues.
