After I replaced my Mac's system drive, Time Machine won't go back prior to the change, even though the data's still in the Backups.backupdb directory.


Here's my system:

MacPro 2x2.8 GHz Quad-Core Intel Xeon, 6GB RAM

320 GB internal drive = "MacHD" = system drive

1 TB internal drive = "HD1" = new internal drive that will replace MacHD

2 TB external drive = "BKUP_TM" = Time Machine drive


Here's what I did:

1. Install and format HD1 as Mac OS Extended (Journaled)

2. Clone MacHD to HD1 using SuperDuper, with "copy all files" and "make bootable" options enabled

3. Remove MacHD and reboot computer with HD1 as new system drive

4. Mount BKUP_TM

5. Allow Time Machine software run overnight to do whatever it wants (it recognized the BKUP_TM drive immediately and without my input)

6. Launch Time Machine software after it completes its activity. This is where I noticed that I could only look back in time 1 day to the point of step 5 above.

7. At the finder level, open the BKUP_TM drive and notice that:

A. The data is all held in one directory (as expected)

B. The data still goes back to August 2012 (as expected)


Here's my overall question:

How do I get Time Machine to access the data correctly?


If I have to, I could reinstall the MacHD drive, erase HD1 and start over, but I'm concerned that even that would not get me back to being able to access the full depth of my Time Machine data in the Backups.backupdb directory.


Thanks, in advance, for the help,


Mac Pro (Early 2008), Mac OS X (10.6.8)

    Do you have all your files on your new internal drive? (HD1)

    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

    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.
