Hello everyone, if possible I would like some advice from someone who has experience with Leopard installation problems on a PowerPC G5.

 

 

Background to my problem:

I recently got a Dual 2.3 GHz PowerPC G5, but it came with my old hard drive inserted, which was in my old 1.6 GHz G5. This hard drive already had Leopard installed previously, which I had been using in my old 1.6 GHz G5. To cut a long story, one day Leopard would not start up (on the 2.3GHz). I tried reinstalling it from the installation disk, archive and install, clean install, but none of them worked! The installation disk works, in that you can start up from it, and use things like Disk Utility etc, but just before actual installation of Leopard, it does this disk verification thing, and it fails that (saying something about 'there is nothing to install onto'). I have also been getting really odd noises from the optical drive, as if there is something wrong with the disk! Some of the sounds were quite loud, and repeating. I tried skipping the disk verification and going straight onto installation, more strange noises from the optical drive, and the installation not progressing beyond a very small way, then a message saying it can't install and to restart. Also, it says something about 'base', sorry should have noted it down. Anyway, I panicked, and tried installing Tiger again, which worked fine! So, my optical drive is fine. I then tried reinstalling Leopard from Tiger, and had more problems, so currently just have Tiger.

 

 

I have some questions please:

1) I tried installing Leopard over basic Tiger 10.4, which failed. I have now updated Tiger to 10.4.11, with all software updates. Does Leopard need the updated Tiger firstly, to be able to be installed successfully?

 

2) Is there a way I can check if my Leopard disk is actually broken, without having to go through another potentially damaging installation attempt, which has previously left me having to install Tiger all over again? The disc worked fine when I upgraded Tiger to Leopard on my old 1.6 GHz G5, why would it have problems all of a sudden on a Dual 2.3 GHz?

 

I am just trying to research this a bit, before I attempt another installation. I had a whole day of installation heart attacks the other week, it really got me down.

 

Thank you for reading,

 

Adam

    Hi Adam,

    Does Leopard need the updated Tiger firstly, to be able to be installed successfully?

    Good question, I don't think so, but never tried it actually.

    Is there a way I can check if my Leopard disk is actually broken...

    On 10.4.11 use Disk Utility to Verify that Install Disc.

    ... why would it have problems all of a sudden on a Dual 2.3 GHz?

    Optical drive may be having problems, 10.5 Install is larger than 10.4 Install... & isn't Tiger Single Layer DVD, whilst Leopard is a Dual Layer DVD?

    You should not have to install Tiger to then install Leopard over it.

     

    Some years ago, I damaged my retail Mac OS X Leopard Install DVD and called Apple (1-800-MY-APPLE) and then sent me a replacement disc for about $17.

    Hello BDAqua, thanks for your feedback on this! When I get back to my G5, I'll try to verify the Leopard install disk with Disk Utility, on 10.4.11. If there are problems on Disk Utility, then I'll refrain from attempting another install, and probably look for another disk.

     

    Regarding your comment about the optical drive having problems. Thing is, if I successfully installed Leopard on a 1.6GHz G5, then shouldn't it also install fine on a Dual 2.3GHz? Are you saying there are optical drives which can't handle dual layer DVDs? I suppose it's possible they've put in an optical drive which can't handle a Leopard install.

     

    Anyway, I'll check out the verify on Disk Utility, just perhaps things will be all right now that I've upgraded to 10.4.11!

     

    Thanks

    Hi MichaelLAX, thanks for the comment. That's what I was thinking, that I should have just been able to re-install Leopard again (over Leopard, and not Tiger). My last failed installation attempt, was over 10.4 (basic Tiger), but now I have 10.4.11, so was wondering if that will somehow aid the installation of Leopard.

     

    I'm going to try and verify the install disk with Disk Utility.

     

    Thanks

    On my iPhone so hard to read your original post: but you need a retail Mac OS X Leopard Install DVD, not the grey machine specific restore disc from a different Mac. Is call Apple and order a replacement disc.

  • Adam Simpson5 Level 1 Level 1 (35 points)

    Hi everyone, the DVD I have has all the leopard graphics on it (black, with the galaxy), came in a box with manual etc, I think it is retail, no grey anywhere.

     

    The other day I verified my Leopard DVD in 10.4.11 disk utility, and got 'volume passed verification', so I decided to have another go at an install. As usual, the Leopard DVD works fine up until the checking installation DVD part, where it gets to about 50% and a message appears saying 'there was a problem reading your disk, carefully clean the disc and try reinstalling'! Gave it a clean with a CD micro-fibre cleaning cloth (hope that was okay), tried installing again, and the same message appears!! Anyone have any ideas to why this is happening please? Like I said, I used the same DVD to install Leopard on my previous G5, so I don't understand why the problem now.

     

    I don't know if this helps or not, but I tried verifying the disk permissions of the install DVD in disk utility (when started up from the DVD), and the message said 'Error, the underlying task reported failure on exit'. Could that be relevant to anything?

     

    Does anyone have any other ideas or suggestions please? I'm worried about getting another install DVD, in case that fails as well! From what I have wrote, do you think the problem lies with the DVD or the optical drive?

     

    Thanks everyone for your feedback!

    Sounds like you have the proper version

    It appears that the verification step is finding an optical flaw on the install DVD.  You could just click on SKIP and not have it check the DVD and hopefully the flaw is not located on a needed file, but I would only suggest you try that after exhausting all other steps first.

     

    My best advice continues to be that you call Apple (800-MY-APPLE) explain that your Leopard DVD appears flawed and they should send you a replacement disc for about $17.

     

    This happened some years ago to me when a MacBook Pro's internal drive actually cut concentric circles into my Leopard install DVD and Apple sent me a replacement:

    Hi MichaelLAX, thanks very much for the help!

     

    So, by the sound of it, you think my problem is with the DVD and not the actual optical drive (as the message tells me to clean the DVD)? I'm just worried that the optical drive has a problem, as that's a load more hassle which I don't even want to think about!

     

    I'm going to have a go calling Apple UK and asking for a replacement DVD. I assume these DVDs are brand new, so if that doesn't install, then I know for sure that my optical drive has a problem.

     

    It's such a headache, all these issues, I just can't seem to be able to have peace on a G5 anymore, and get on with some work! It's like I'm braced for another problem at any minute!!

     

    Thanks

    Have you tried any other DVDs recently; do they work?

     

    I put my iMac G5 to rest after it failed for the last time back in Fall, 2011: R.I.P!

  • Adam Simpson5 Level 1 Level 1 (35 points)

    Hi Michael,

     

    I installed Tiger from a DVD fine, and the Leopard DVD does work up until the Disk verification part, so going by these things, it's pointing to a fault with the DVD and not the optical drive.

     

    I called Apple UK, and although they said they do not make Leopard disks anymore, they very kindly offered to print me one and send it free of charge! So, if this fails, then there must be some sort of an issue with the optical drive. I'm hoping this will resolve the matter.

     

    Can I ask you? I did actually install Leopard about 2 years ago, on an old G5 which is now gone, so the DVD did work back then. Is it possible that my current G5's optical drive somehow did something to the DVD which is causing the non-installation issue, because it doesn't make sense why it worked 2 years ago and not now. The DVD has just been kept secure in its case. When I examine the DVD though, it does actually have quite a lot of marks on it (caused by the previous owners though).

     

    Thanks

  • MlchaelLAX Level 4 Level 4 (1,905 points)

    I would not expect the DVD to fail just because the passage of two years.  But if it was abused before you acquired it, perhaps the alignment on your DVD drive is just so slightly out of alignment to cause this disc to fail while high quality discs still run.

     

    You can research adjusting the alignment in your DVD drive, if you are handy at doing that type of repair.  Otherwise, I suggest that, if it works otherwise, just leave it alone and wait for the kindness that Apple is providing by sending you a copy of Leopard FOR FREE!

     

    Another thought is that external USB DVD drives are down to about $40 here in the states and if your internal one fails, it might be more economical to just purchase an external one.

     

    I did some years ago, because it gave me DVD-DL (double layer) burning capability, which my iMac G5 at that time did not. This allowed me to use Toast to burn BluRay formatted HD/AC3 media to an 8 GIG DVD-DL, which then plays in my BluRay player. 

     

    This also turned out to be handy when i replaced my iMac G5 with the 2011 Mac Mini which does not come with an internal DVD drive.

     

    I doubt that a desktop's DVD drive damaged the disc.  My experience of damage came from a specific model of MacBook Pro that had reports of some drives causing DVD damage.  Apple replaced that DVD drive without cost.

     

    But anything is possible! Good luck and report back!

  • Adam Simpson5 Level 1 Level 1 (35 points)

    Hi Michael, when you say alignment of my DVD drive, do you mean with the positioning of the DVD (when I've put it in the drive) in relation to the part of the drive which does the actual reading? So, if perhaps, the DVD was moved a fraction (when in the drive), it might actually complete the installation?

     

    Anyway, other DVDs seem to work fine, so I think I'll just wait and see what happens when the new DVD arrives, and I'll let you know. I'm hoping this DVD will install, as I'm getting a bit fed up of Tiger, many web sites don't work properly with the Safari which is on it.

     

    Thank you

  • MlchaelLAX Level 4 Level 4 (1,905 points)

    Yes, please report back after new copy arrives.
