View Full Version : Reformat HD and re-install OS first -- possible?

I have been having considerable problems with iTunes and an Apple "genius" said her (successful) solution to the same problem was to back up her entire system drive, reformat her system drive, install a new system, and restore all her files (which she did by hand). As things have gotten intolerable, I've decided to follow her recommendation -- except I've purchased a new, larger drive (for my Dual 2.5 GHz PowerPC G5 desktop running OS X v10.4.8) to replace my original system drive while I'm at it.

I read the post "Best process to replace internal hard drive using SuperDuper!" below, which appears to detail most of what I need to know. However, two questions:

I intend to install a fresh, new copy of the OS on the new drive first, since part of the solution seems to be replacing any potentially corrupted OS files (and reinstalling over an existing system doesn't always work). If I do this, and then use SD! to copy all my files back onto the new system drive, will it copy my old system files over the newly installed ones (potentially replacing "good" files with corrupted ones), or will it leave the new system files alone (since, in theory, they should have either the same date or a more recent date)?

Also, I currently use SD! to backup my system drive to a (bootable, fully functional) partition of a much larger drive. Can I run all the preliminary tests described in the above post on the partition, and run the entire procedure using that partition to hold my backup files? Or should I delete the partitioning, erase and reformat the whole drive, run the tests, and backup to the unpartitioned drive to make sure everything works flawlessly? (The latter would be a real pain, for the other partitions hold other files -- but it would be doable.)

Thanks in advance for any and all assistance.

Actually, if your plan is to reinstall, I'd just update your backup, do your clean install, then use the Migration Assistant to migrate from the backup to the fresh drive.

I wouldn't touch the backup: no need. But, when you say "fully functional", does that mean iTunes is OK on the backup?

Great idea! Why didn't I think of that? I presume the Migration Asst will have no problem recognizing my backup partition as a "drive".

Another good point. I haven't actually tried running iTunes from the backup. I HAVE run diagnostic tools, email, and a few other things, all of which worked fine. I'll give it a try...

(Meanwhile, I am also attacking the problem from another front: I have just discovered Apple's support document on rebuilding your music library. [They could have made the process a lot easier!] Am in the process right now.)

Many thanks for your help.

OK. Let us know how things work out.

OK, I followed the plan, except that I installed a brand new system on the new drive and then used Migration Assistant to copy back everything (except System files) from my SD! clone.

So far (about 5 days), everything seems to be running OK. The biggest noticeable glitch was that the rebuilt iTunes Library lost track of quite few music tracks and podcasts. Turns out they're all in my Itunes Music folder, just not listed in the Library file; it's a pain, but all I need to do is drag and drop the "missing files" back into iTunes again and voila, they're listed again (right place, right info, etc). Knock on wood -- aside from this one issue, iTunes is behaving well again.

Thanks again for the assistance.

Glad it worked well for you!
