I am having a heck of a time restoring a machine with Time

Customer Question

I am having a heck of a time restoring a machine with Time Machine. I had a bad HD replaced in my Macbook Pro running 10.5.x. It is a long story involving machine hangs during restores and backups. The laptop had no problems before the new HD install (by Apple). At one point I though I had everything working - I upgraded to 10.6.1 and tried a TM backup to the same disk. It hung and now the disk (data) seems corrupt to some point. The last time I tried to use it the machine said:

The backup was not performed because an error occurred while copying files to the backup disk.

It now seems to be mounting read-only.

I am now running 10.6.1. It seems to be running fine but I don't know if I got all the data off the backup. I'd like to move the TM backup data to another disk, re-format the TM disk, and start a fresh backup. I formatted another USB drive to "Mac OS Extended (Case-sensitive)" like the TM disk. When I try to copy a folder from the TM disk to the new disk I get a messa

Hello my name is Dan.
One of the biggest problems you have is the format. Case Sensitive is rarely a good idea.
Reformat as Mac OS Extended (journaled) NOT case sensitve.
This may solve the TM issue.
If the original TM is still intact then I would check to see what the new drive is formatted as.
It may be that it has the wrong format. Like I said case sensitive is something that software developers use and not many others for the very reason you are experiencing.

Let me know.

Thanks for the input. The TM disk was "default" formatted by the OS when I told it to use as a TM disk. I never explicitly told it to be case-sensitive. I tried setting up the second disk as you stated before. When I tried to copy the files it told me there was a mis-match between he formats. I reformatted the second disk to exactly match the TM disk but now I get a generic message "The volume is the wrong format for a backup.". Interestingly, when I check the info on both drives, they both say "Mac OS Extended (Case-sensitive)" so they do match.

Why does it give the message "wrong format for a BACKUP" when I am simply attempting to drag-and-drop (copy) the directory from one machine to the other.

(Incidentally, just FYI, I am a developer with 30 years experience with Windows and Unix.) It seems like the TM disk is not treated like a regular volume. Thanks. XXXXX

It isn't treated like a regular disk. Just because TM formatted it doesn't mean it did it right (see below).
I am giving you a link to a TM trouble shooting KB that I use and it will save me a lot of typing.
And this also. I find both good with some overlap.
Let me know.
