SD cloned drive switched to internal will not boot
Background:
Upgraded an imac G5 ppc 10.4.11 w/ a shiny new Hitachi 2TB SATA I/II/II 6gbps 64mb cache but it kept overheating the cpu DANGIT and sometimes shut the whole thing down -- yikes! Guess the PPC G5 just can't handle those parameters even though it is backwards compatible according to the tech info/specs. Great if you have a newer setup, eh? So I'm gonna use the Hitachi as a backup drive and an also-new 2TB Western Digital WD Green Caviar Intellipower which was originally the backup up used to Super-Duper clone/all files backup from the Hitachi. Only about a week's worth of minor differences so I moved the WD (which seems to run much cooler) into the internal drive spot. Startup/Boot Problems: I can boot from the overheating 2TB Hitachi via an external firewire dock, but I cannot boot from the now internal 2TB Western Digital, which was cloned via copy all files (~ approx a week ago). If I try to boot from the WD-internal, the Startup chime occurs but then it gets stuck on the grey apple logo screen, no widget ever starts to turn; the fans kick in loudly after a while. I can't seem to CMD-S single user boot from it NOR safe-boot (shift startup) from the WD-internal either. I have to shut down via the power button and then: Have to use the Option-key boot -> to the Hitachi external Firewire dock which boots fine (and the temps stay much lower/acceptable range when it is the external drive) and the WD is the un-booted internal drive. WD-internal gets recognized in the Option-key boot screen BTW as having an OSX system. As does System Preferences > Startup Drive (when I boot from the external hitachi). When I boot from the external firewire Hitachi (now), I can see and access the WD-internal and all WD folders/files/contents via the desktop; I can copy and install items onto that disk. WD-internal is recognized by both disk utility & system profiler. I just can't boot from it. While booted from the external Hitachi, use Disk Utility, disk permissions were checked/repaired/re-checked, disk verified, repaired (nothing needed), and re-verified -- but WD-internal just won't boot now that it is the internal hard drive. I wondered if there were jumpers so I read info on the Western Digital drive that said it should be ready to use, and in fact it was super fine as an external drive. There's a difference of about 4GB in the log which was what I presume were virtual memory and related files -- see the bold part below. Here's the confirming excerpted part of the log: <snip>So, is there something I'm missing here, something that should have been in those 4-5GB not copied perhaps? Sorry this is so long. Would appreciate feedback on what I may be misunderstanding or missing here cuz I thought a cloned drive would boot and I think I've done so before in fact. Thanks! from a baffled but determined fellow mac user. more system info in case that helps: 2005 imac G5 ppc (non-intel) 20-inch 2.0ghz ALS Mac OS X 10.4.11 Machine Name: iMac G5 Machine Model: PowerMac8,2 CPU Type: PowerPC G5 (3.1) Number Of CPUs: 1 CPU Speed: 2 GHz L2 Cache (per CPU): 512 KB Memory: 2 GB Bus Speed: 667 MHz Boot ROM Version: 5.2.5f1 for others who are upgrading whether you have imacs, intel, G5, dual core, old macs or whatever, there are some great deals on drives these days. I researched a bunch of drives while I was upgrading BTW. Here are some: Last edited by hapmac; 04-20-2011 at 10:39 PM. |

Are you sure that this Mac is compatible with the drive you installed? Sounds to me like it isn't...

Is it possible it would be okay as an external, but not internal? And how come it shows up everywhere if it's not? I mean it's the internal drive now, and I can use it for storage but it won't boot. So weird, huh? Thanks for suggestions! |

As an external, it just needs to be compatible with the controller in the case. Internally, it has to be compatible with your G5s controller. It clearly isn't.

okay well dangit. Do you know how I find out what the controller is or where to compare definitively for compatibility? |

Perhaps talk to Apple, or a hardware focused company like MacFixIt or OWC.

So I guess it'll be my 2nd external backup and I'll have to go back to an older backwards compatible hitachi for now and will have to save up for a whole new Lion based rig sometime this year (or next)! :-) cheers/thanks again Dave! Last edited by hapmac; 04-20-2011 at 11:15 PM. |

it might be the jumpers...
just a quick update. Again, all the WD info I found seems to indicate this WD20EARS drive should be compatible w/ OS X...although nothing specifically matched g5 ppc 10.4.x that I could find yet.
But I found a reference to some specs & jumper settings for Specifications for Caviar Green and Caviar GP Serial ATA hard drives that may be required for backwards compatibility to 1.5/3.0gbps that I'm going to try; specifically the very bottom of the 2nd box called 'PHY enabled' which is also the same settings as 'OPT1 enabled' in the first box. do you have any thoughts about this by any chance?

It's unlikely this is the problem, although you can certainly try. We know, though, that the copy is fine, since it works externally...

Realize this is late and you may no longer be reading this. Plus, I think Dave has it right as usual. BUT, one thing you could try, which apparently you haven't or at least you haven't mentioned it, is to recopy to the WD. Use SD to do a "Backup-all files" to it using "Smart Update" and see if it boots. If it doesn't then do the same full backup to it, but using "Erase, then copy." Either way, you still have your full backup, and it could work. (But probably won't.) Have fun. |
