How did you "Copy" the contents of your old Macbook
Used SuperDuper to create a bootable clone of the Macbook to an external disk, then replaced contents of MBP with that clone. (The refurbished MBP came with Lion, but I have too much investment in software that requires SL.) This procedure worked perfectly for me last year when I replaced the hard drive in the Macbook. The same external disk is also the one that Time Machine uses. Since transferring files to the MBP, all software works normally on the MBP, as far as I can tell, except for TM.
Given that you have a good backup already,
I would suggest that you reformat that Time Machine drive and start again with it.
Had it been working correctly, it would have done a full backup the first time anyway.
so problem is external, not internal?
Sounds like you are recommending that I completely reformat the drive that time machine backs up to. Seems to indicate that the problem is with that drive, and not with the MBP? Does that mean that TM is hitting that file on the backup drive and can't get beyond it, rather than trying to copy that file from the MPB? Just want to make sure that the problem is in the external drive, and not on the MBP. Thanks.
As soon as you used the Clone on the MBP drive,
the Time Machine backup became useless.
All the dates were wrong, the files were changed, and the index was totally out of whack.
You have what amounts to a decent backup right now, but making another clone before wiping out the external would not go amiss and is encouraged.
Right now I think the problem is with the existing TM configuration on the external.
Clone to new drive?
The LaCie drive that contains the TM backups is also the one with the clone of the MB. SuperDuper makes a clone without disturbing the backups already on that drive, or so it says. If I wipe out that drive completely, I will need to purchase another drive to clone the computer. Am I understanding this correctly?
Time Machine drive.
You can use the TM drive for things other than the backups as long as you have space on the drive.
TM puts the backups into a folder so any space outside of the folder is fair game.
Yes, if you wipe out the external drive everything on it will be destroyed.
For the brief period of time between the re-format and the start of the TM backup, you will be without a backup of any kind.
If this poses a problem for you, then your only recourse is another external drive to create a new clone to.
SuperDuper does not allow backups to be created to a CD/DVD or tape.
Perhaps a re-format and then a new clone followed by a TM backup would be the order to go with.
Wipe Out method?
What is the best way to completely reformat the external LaCie drive? I think with a new MBP I ought to be able to go without a backup for the short time of the reformat. Then I can make a clone, and then fire up TM again with BACK UP NOW, as you suggest above.
Use Disk Utility to reformat the drive
you may have to use the Erase option first, you'll see as you proceed.
OS X Extended (Journaled) is the format you want.
Make sure, under Options (at the bottom of the window) that you have GUID selected.
Don't See GUID
Disk Utility only shows Erase Free Space, Security Options, Erase
Nothing about GUID.?
Erase the disk first and then
close Disk Utility.
Reopen DU and choose Partition.
Then you will see the Options button at the bottom left of the window
I was able to erase the disk and then make a new clone and then TM started working just fine. Thanks for the help.
Pleased it worked for you
