You're not confused at all by the looks of it. Have your friend run ASP
and discover the current version of the firmware - Production Info->ROM
revision/bootROM version, or something like that. Obviously if it's
already v4.19 then an update is unnecessary. OW, run the updater (under
OS9 of course, booted from the HD), then do the Tiger upgrade. Eazy peazy.
Well, so far so good - sortof. Kindof a combat log, I guess...
Normally, I build a HD on my own Mac and just slap it into the other
Mac. Fast and easy. But I don't normally do iMacs and my friend
wasn't excited about the idea of opening it up. So.......
The iMac came over yesterday. First thing we figured we'd do is make
a cloneish backup of the HD using firewire target disk mode to an
empty partition on my Smurf, using CarbonCopyCloner. This would
provide easy access to user files and 3rd party apps.
Four hours later we were still unsuccessful. Mounting the drive on
my Smurf took forever and/or hung. Opening the drive in the Finder
took 5+ mins and/or hung. CCC (ditto) was hanging. Nuking Spotlight
didn't help. Disk Utilities verify/repair functions passed fine tho.
Oh what a fark - when a Finder operation hangs in this way, you're
toast. You can't kill it except by hitting the Mac's reset button.
So much for OS X's better app control.
Booted the iMac in OS X, turned on file sharing and copied the
important stuff over to my Smurf.
Booted the iMac in OS 9 and ran the firmware updater. hum. Firewire
fix maybe?
Booted in target disk mode ... voila - the drive now mounts on my
Smurf quickly and works well!!!! woohoo!
Four hours later, ditto was hung again. Finally found a note in the
CCC FAQ that says that happens sometimes, over target disk mode.
Gotta love them unfixed Apple bugs.
Ok. So CCC a few directories at a time, overnight. 8am - backup done.
Erase and zero the HD (give it a good block-by-block exercise). CCC
my core system into it, a few directories at a time. Noon done.
Manual sudo ditto to move the old user data to it (same command as
used by CCC, and a bigger copy operation than CCC's, but it worked
without hanging!). And it booted fine the first time! Now gotta
make a few settings changes and install some 3rd party apps...
LESSON: Update that firmware FIRST! arg.
LESSON: Remember to kill Spotlight! If you don't, it will suck away
your cpu and i/o bandwidth while CCC is running! arg arg.
QUESTION: Is there a way to turn off or dim the iMac's screen while
it's in Target Disk Mode?
QUESTION: Is it normal for CCC (ditto) to run at a whopping 2 KB/sec
(according to Activity Monitor)??? These two Macs (300 and 500 MHz)
can *easily* do fast enough i/o to swamp out the involved buses. So
what the deal? Is this a buffering problem with ditto or lame OS
Xness or ?
Are we having fun yet?
