My G4 won't boot off a firewire drive cloned from properly-booting drive

I've got a G4 that normally boots 10.3.9 off an external firewire drive. I cloned the drive onto a WesternDigital "MyBook" external hard drive, and connected it via firewire 400. I cloned the 10.3.9 boot drive using SuperDuper to a partition on this drive. But, the G4 refuses to boot off it when I choose it as a startup disk. I see (very briefly) the following
....couldn't read it.... @d/mac-io@7/ata-4@1f000/disk@0:5,\\:tbxi
anyone know what this is, why it won't boot off the clone, and how I can check whether the drive contains a proper 10.3.9 system and is set to be bootable?
Mike

Hi Mike-
How did you know?
I "Googled" it. It's been reported many times, and is included in a couple of reviews.
Problem is, "bootable" can be claimed in Mac's, as it will boot with Intel machines.......
Don't ya' just hate that?????

Imac G4 700 - can I boot off a firewire drive?

The internal hard drive in my iMac G4 has died. I'm not afraid of working inside computers, but from what I've read online, it appears to be a major pain in the *** to replace the hard drive on this generation of iMacs.
Is it possible to boot off an external firewire hard drive instead of trying to replace the internal one? I would probably just buy a firewire enclosure off newegg and stick a standard IDE hard drive in it. Will this work?

Hello and Welcome to Apple Discussions.
I would
also like to say that some cheap Firewire chipsets are unreliable for booting. I could never get the Prolific 3507 chipset in one of my Firewire drives to boot. Go for an Oxford chipset if you can. There's loads of choice here:

Booting off external firewire drive

Hi Ive cloned my internal imac drive using superduper.
Inside the startup application i can now see my external drive as bootable.
I am trying to boot off the external drive TARGET disk mode. Is this correct to get the os to boot off the external FW drive?

Hello Joe.
You don't use Target disk mode to do so. When connected, you can select the external firewire drive to boot from via System Preferences > Startup Disk or use the Startup Manager during startup or restart.

G4 Sawtooth won't boot off of firewire drive

I have a G4 Sawtooth that I connot get to boot from my firewire external drive.
The machine is running Panther(10.3.9) and the firewire drive has Tiger(10.4.5).
Don't know if this is the problem, but don't believe it is.
Just updated the firmware to 4.2.8 and still won't go.
What should I try now?

Nicolas, welcome, did you boot from OS 9.1 or 9.2 for the firmware update. And exactly what happens when you attempt to boot from the external.

Mac Pro 8 core with boot drive cloned from MacBook Pro

I bought a Mac Pro 8 core and in order to avoid having to reinstall all my stuff, I cloned my OSx (tiger 10.49) partition from my MacBook Pro running vista (installed via bootcamp) to my new MacPro's startup disk. The disk works fine except that the MacPro will not boot to osx unless I use the option key and choose the OSX partition. If i just turn the machine on it doesen't find anything. I think it is looking for windows. What do you think?????
Also, if i restart from the os x partition on my mac pro it stops just before the lound bong sound and seems to be looking for the dvd drive. Any ideas??

Well, I've covered this extensively here:
A Basic Guide for Migrating to Intel-Macs
If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
Rosetta supports "software that runs on the PowerPC G3 or G4 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
Classic Environment, and subsequently any Mac OS 9 or earlier applications
Screensavers written for the PowerPC
System Preference add-ons
All Unsanity Haxies
Browser and other plug-ins
Contextual Menu Items
Applications which specifically require the PowerPC G5
Kernel extensions
Java applications with JNI (PowerPC) libraries
See also What Can Be Translated by Rosetta.
In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior (does not work), TechTool Pro (pre-4.5.1 versions do not work), SuperDuper (newest release works), and Drive Genius (untested) may not work properly on Intel-Macs. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries.
Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.

Transferring data with Setup Assistant - Migration Assistant FAQ
Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode or copying the critical contents to CD and DVD or an external hard drive will work better when moving from PowerPC to Intel Macs.
Basically the instructions you should follow are:
1. Backup your data first. This is vitally important in case you make a mistake or there's some other problem.
2. Connect a Firewire cable between your old Mac and your new Intel Mac.
3. Startup your old Mac in Target Disk Mode.
4. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
4. Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder)
/Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder)
/Home/Library/Mail (copy the whole folder)
/Home/Library/Preferences/com.apple.mail.plist (* This is a very important file which contains all email account settings and general mail preferences.)
/Home/Library/Preferences/ copy any preferences needed for third-party applications
/Home /Library/iTunes (copy the whole folder)
/Home /Library/Safari (copy the whole folder)
If you want cookies:
/Home/Library/Cookies/Cookies.plist
/Home/Library/Application Support/WebFoundation/HTTPCookies.plist
For Entourage users:
Entourage is in /Home/Documents/Microsoft User Data
Also in /Home/Library/Preferences/Microsoft
Credit goes to another forum user for this information.
If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.
Written by Kappy with additional contributions from a brody.
Not knowing what you did when you migrated from your PB to the MBP, I can't really comment, but it's quite possible it didn't go as well as you think. Numerous users who migrated from PPC Macs to Intel Macs ended up with an Intel Mac that didn't work properly because Intel coded components had been replaced by PPC coded components.

Booting Intel Mac and PowerPC Mac from same external drive

Seems to be difficult. My previous experience and experiments made me conclude you need a separate firewire drive for each variety of Mac. But
http://rentzsch.com/tidbits/intelbasedMacBootIncompatibility
does list a method with which this can be done. I hope. Will give it a try. Hopefully this means that down the road this won't really be a question.

Mac Pro Early 2008 will not boot off Win7 Install DVD

Hello,
I am hoping someone out there will have encountered something similar and have some suggestions or ideas, because at this point I can't think of anything else to try.
I have a 2.8 Ghz 8-core Mac Pro (Early 2008) with an Nvidia 8800GT Graphics card. I am running OS 10.6.2, fully patched and updated.
I am attempting to install Windows 7 Ultimate via Boot Camp, and am encountering a rather odd problem.
Once I have launched Boot Camp Assistant it allows me to partition the drive and does so correctly, but when it attempts to reboot off the Windows 7 installation DVD, I encounter a blank grey-white screen similar to that which you normally get on startup but without the Apple logo. This continues for some time (it seems to vary), and then the screen goes dark and the monitor says it is receiving no signal. The fans on the Mac Pro go for a while, then it goes to sleep. I've tried leaving it for a couple hours, no dice.
I've tried both the 32-bit and 64-bit Windows install disks. I had the release candidate for Windows 7 installed previously, and it worked perfectly. I have since tried that same install DVD that I used to install the release candidate, and it encounters the exact same issue. Booting up off the Snow Leopard Install DVD works fine.
I tried doing a clean install of Snow Leopard on a spare drive, booting off that, and then starting from square 1 using Boot Camp Assistant to re-partition that same drive. Same problem. No matter what I do or try, my Mac Pro does not want to boot off this install disc. I have yet to try the disc in another machine to see if it works there, and I will as soon as I can, but the fact that the RC disc worked a few months back and now will not seems to rule out the boot discs as defective. I've also tried both my internal optical drives with no change, and no other discs have any issues.
I've already spent an hour and a half talking to Apple Technical Support, and they seemed stumped, so I'm hoping someone will have a notion. If not, I understand and appreciate you taking the time to read this- I have no idea at this point, and I'm generally a pretty knowledgeable user.
- Andrew

Thank you for your reply,
Pull all the drives you have other than the one that you will install Windows 7 to.
I think I will try this next.
Don't put Windows 7 on the same drive as OS X, give it its own.
That was initially what I started out doing.
And you don't even need Boot Camp Assistant.
True, but it's what Apple suggests using.
Might also want to try moving the monitor cable to the other card port.
Hmm, I think I'll try that.
Any other PCI cards or devices attached or installed should also be questioned or disconnected.
I've disconnected everything I could.
Always a good idea to start fresh which I assume you are doing (not trying to upgrade over RC etc).
Yes, the drive was empty to start with.
Honestly it seems like the Mac Pro is generally refusing to boot from any Windows disc. Things I've tried since my initial post:
- Loaded Windows 7 Install disc into my room mate's windows PC... loaded up fine, got to install screen
- Tried his OEM copy of Windows Vista 32-bit, same issue
At this point it seems like maybe some kind of firmware issue or some kind or graphics driver issue, but I'm pretty much grasping at straws at this point. It doesn't seem like it's even getting to the point where hard drives or anything matters.
It does recognize that I have a Windows 7 install disc inserted when I use the boot selector/startup disk chooser.
Thanks for the ideas, I'll try those out and see if any of them help,

All drives apart from boot drive completely wiped!! HELP!!

Just booted up my G4 1.25GHZ which has an internal drive and 2 firewire drives attached. All files on all the drives apart from the boot drive have dissapeared.
The drives are empty1 That's 600GB of data that's just vanished. The only thing I can think of is I'm using Personal Backup from Intego for backing up data mostly in the background and it seemed to be taking ages to repair permissions yesterday. But it wasn't backing up on all the drives.
I'm trying Techtool pro to recover the data but I need to know what happend...
Help if you can, thanks.

Have you tried the drives on another computer to see if the files are showing up? This might be a problem with the FireWire jacks or OS X not recognizing it anymore, it happened to me once, I had to reinstall Panther at the time and it was a bad memory chip that caused OS X to behave improperly.
If the drives work on other systems, you should try reinstalling OS X and if it still does not work, try the Hardware Test that came with your computer.

Going from 10.3 to 10.5... can i still boot 10.3 from an external drive?

I want to switch from 10.3 to 10.5, but I have some important software and hardware that only works with 10.3. Can I copy my current hard drive information to an external drive, and then essentially boot up my old computer setup from that external drive whenever I need to use 10.3?
How would I go about doing this?
thanks!

System Preferences >> Startup Disk >> choose the one you start from and press restart. Or boot to Startup Manager.

Slow boot from external usb drive

I just upgraded my daughter's macbook to the latest fixes on her internal drive. I reformatted her external LaCie drive to Mac OS Extended(Journaled) and did a restore. I did notice that there are less files on the internal than the external drive when comparing immediately after the restore. When I try to boot from that drive, it takes 10 minutes to boot the system. It takes about 7 minutes before I even hear any drive activity. In the past this system used to take about 2 minutes to boot at most vs 30 seconds from the internal drive. I have repaired permissions without seeing any effect. I did attach another USB drive that had a copy of her old OSC 10.5.8 image and that booted in less than 2 minutes. Any thoughts on what could be causing the long boot time on the external drive? I have seen comments on GUID formatting. Doesn't that come automatically with Mac OS Extended(Journaled) on an Intel machine? Should I have selected an option when doing the format to specify GUID? I did run a verify Disk as well and the extrnal checked out without any problems.

+" ... and did a restore ..."+
How, of what, from where, to where?
+" ... I have seen comments on GUID formatting. Doesn't that come automatically with Mac OS Extended(Journaled) on an Intel machine? ..."+
No, it does not happen automatically when you format the drive. GUID is a partition type, not a format. You specify GUID partition scheme at the time you partition the drive. Formatting is a separate operation, occurring after partitioning. Drives that will be used to boot an Intel Mac must be GUID partition scheme and formatted as Mac OS Extended Journaled.

Can I dual boot Snow Leopard and Mountain Lion on one hard drive?

I want to make a new partition and be able to boot to either OS. Is this possible, if so, how? I would think just make a new partition and install the dmg file to that new partition.

@jimmyk11: AppleCare has actually informed me that "No - this MacBooPro9,1 cannot boot Snow Leopard".
It originally came with lion 10.7.4 installed. I have since upgraded to Mountain Lion 10.8 and (today, after a week or so of ML) I reverted to Lion 10.7.4. But now I find I can no longer boot into Lion 10.7.4 from my external FW800 drive (for troubleshooting and housekeeping). So it looks as if the "boot problems" are not confined to Snow Leopard 10.6.8.
Interestingly, I can use this same external drive to boot my iMac (10.7.4) and my older MBP8,3 (10.8) into 10.7.4 - but not the newer MBP9,1.
The MBP9,1 with Lion and Mountain Lion is turning into a disaster when it comes to external booting. If I could, I'd demand a return and a refund. After bottle-feeding Lion for a year, 10.7.4 seems basically stable and can still boot into Snow Leopard and Lion from my external drives if needed. But now I see I have a worse problem: Crippled Hardware. I suspect this bug needs a firmware update - if it is fixable at all.

When I boot up my Mac, Messages opens automatically. I quit the app, but it just re-opens itself. It won't stay off!!! I can't figure out what's wrong with it!

For the past few months, my Mac has been acting weird. EVERY time I boot up the computer, Messages opens automaticallly (I am runing OS X 10.8.x). I quit the app, but it just re-opens a few seconds later! It just won't stay off! I've looked it up online and nothing helps. I have no idea what to do!!!

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Why won't iMac boot off external HD?

Hi I need help setting up a computer and when I connect my external hard drive it won't allow me to boot from it when I start it up holding (option). It lets me pick between recovery and the external and built in hard drive?

If the computere you are setting up is a New Mac and the external hard drive you are using is from an older Mac that is why it won't boot off the external. All New Mac's come with Special Builds of the current version of OS X and they will not boot or run off an older version of OS X Even IF that older version is the same Base version, like Mt Lion 10.8.x.
The version of OS X that is installed on newer Mac's have the correct Drive Package for the newer hardware. The external does not have the correct drivers.

MacBook Pro won't boot off Tiger CD

I installed a larger drive into my MacBook Pro. I inserted the Tiger OS X cd, and pressed the 'C' ket to boot off the cd. It doesn't recognize the start-up disk and goes to the "? Folder".
I zapped the PRAM, etc. with no change.
I can boot off an external drive with OS X installed by holding down the "option key" at power up, and selecting that external drive, BUT it doesn't recognize the OS X CD in this mode either.
If I use the external drive to boot from and insert the Tiger CD, I can only go so far in the installation process before I get a window that says "You can not install OS X on this computer". I've only seen this window when trying to install a lower version of os x onto a drive that has a higher version installed. As my new drive is blank (OS extended), it seems I should be able to install Tiger on the empty drive. Right?
Any suggestions?

The MBP is an Intel based computer vs. the PPC based G4 or G5 or anything earlier. They started being produced in 2006 (which for me is new, with my 2000 model ). Texas Mac Man provides some history as to the OS versions, but all the early ones came with their own version of Tiger. You can't even use a retail installer version of Tiger since it wasn't considered necessary to provide a retail version of Tiger for a computer series that came with it anyway.
If you are using a G4 installer it is definitely the wrong disc and you're getting exactly the message we'd expect. Sometimes it won't even get that far.
If you can't find the discs it may be possible to clone your old drive to the new drive. This is assuming the old drive is still viable and you have an enclosure in which to put the new drive while attached to the computer with the old drive inside. If you use a tool such as Carbon Copy Cloner it will place a bootable complete duplicate of your one drive onto another.
