Booting os x from partitioned external firewire drive?

Hi all,
my internal hard disk (on a 12" powerbook G4 867 mhz running osx tiger 10.4.10) has started acting weird (many people are reporting failing hard drives, and I'm assuming mine is failing too), so I'm preparing for replacing it with a new hard drive.
I've backed up the drive to an external firewire drive (LaCie portable 80 GB firewire drive "Design by F.A. Porsche") using Carbon Copy Cloner with the option 'make bootable' selected.
PROBLEM: I can't boot OS X using my clone on the external drive.
I'VE TRIED:
1. holding down Command-Option-Shift-Delete while booting to bypass the internal drive. (This didn't work: I saw an os 9 icon blinking/alternating with a question mark for a while, and then the computer booted from the internal hard disk.)
2. holding down Option to select the external drive in Startup Manager. (Didn't work either: Startup Manager opened fine, but only showed my internal drive volume. I tried clicking the 'rescan' button, but it couldn't find my external drive.)
3. SELECTING THE EXTERNAL DRIVE under Startup Disk in System Preferences. Note that the external drive volume *did show up* there. So under some conditions at least, the external volume is identified as a bootable volume. (This didn't work either, though: When I shut down the computer and booted up with the external drive connected, it still booted up from the internal drive.)
POSSIBLE EXPLANATION?
My external drive is partitioned into three partitions of different formats:
1. "Mac OS X Extended (Journaled)"
2. "Mac OS X Extended (Journaled)"
3. "MS-DOS File System (FAT32)"
The bootable volume is the first partition with the os x format.
Could my problem be caused by this partitioning of my external drive?
Either way, what to do?? I hope some of you savvy people out there can help me out.
Cheers,
Philip

Hi Philip,
My problem has been fixed, & I imagine it's the same for you...:
With the excellent help from Dave Nanian at shirtpocket.com - the developer of 'SuperDuper!' (thanks Dave - you rock!), the problem (as Michael suggested) is to do with the Partition Scheme of the drive.
If your drive was like my portable LaCie Porsche drive, it was FAT32-formatted for PC out of the box. This format has an underlying MBR (master boot record) partition-scheme. When re-partitioning a drive in 'Disk Utility', the original partition-scheme sticks, so if you simply re-partition the drive to Mac OS Extended, it will still have an MBR partition scheme... which Macs cannot boot from!
For a Power PC Mac to be able to boot from an external firewire drive, the drive MUST have an APM (Apple Partition Map) Partition Scheme underlying the Mac OS Extended partitions. To do this, click on the 'Options' button in 'Disk Utility' when on the 'Partition' page before partitioning. You will see the options:
GUID Partition Table (for Intel Macs... (n.b. Power PC's cannot boot from a GPT drive))
Apple Partition Map (to create a bootable drive for a Power PC Mac)
Master Boot Record (to create a bootable PC drive)
So.... to make your external drive bootable for your Powerbook G4, choose 'Apple Partition Map' in the 'Options' page prior to partitioning.
Special note about Intel Macs: Contrary to info supplied by Apple, an Intel Mac CAN boot from an APM-partitioned drive (this is why the OSX installer can be univerally bootable!), BUT, the problem is that the OSX installer will NOT let you install OSX-intel on an APM-partitioned drive....
You can, however, clone an Intel-Mac-OSX internal drive that has a GPT partition-scheme (using CCC or SuperDuper) to an external drive with APM, & the Intel Mac will still be able to boot from that clone...
The only real use for doing this, though, is if you want a multi-partitioned backup drive with separate bootable partitions for OSX-PPC & OSX-Intel machines. (Remember that a PPC machine cannot boot from a GTP-partion-scheme drive, hence the need to use APM in this instance seeing as the Partition Scheme applies to the entire drive (it can't be different for each partition.)
Good luck - let us know how you get on!

Booting my imac from an external firewire drive suddenly stopped working. Disk still mounts but it will not boot the machine!

I took my MacBook Pro in for repairs and erased the drive for safety AFTER having copied the entire contents to an external firewire 800 drive using SuperDuper!
The copy process made the disk bootable and I was able to boot up my iMac and run it just as if I were working on my MacBook Pro. After a couple of times working this way, the iMac stopped booting from my drive.
The drive shows up when starting up by pressing the option key but then, after a long time, the iMac shows a circle/slash symbol as if it can't find the system files.
If I restart without pressing the option key, the disk mounts on the desktop and I can use it as an external drive just fine! I tried selecting it in System Preferences as the startup disk, but the same thing happens, blank grey screen with the circle/slash.
Since this happened with a Seagat drive - a brand that has failed me in the past many times - I thought it was a disk problem. I had backed up my MacBook pro contents to another Toshiba drive, and booted from there perfectly well for a couple of times...
Until the same thing happened! Thank God I didn't trash the Seagate although it makes very faint clicking noises that will keep me far away from using it again anyway... but that's another story!
iMac runs 10.5.8, the boot disk (and my MacBook) runs on 10.6.8 if that makes any difference... And now I'm scared that when I copy back to my MacBook Pro it might not boot up at all!!!
What gives???

You need to reinstall Snow Leopard onto the external drive:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

Booting the Mac from an external USB drive

I was under the impression that you could only boot a Mac from an external firewire drive. However, I have just successfully booted my new MacBook from an external SuperDuper backup connected via USB.

I was under the impression that you could only boot a Mac from an external firewire drive.
That basically only applies to Mac OS X on PowerPC Macs, not on an Intel Mac such as a MacBook.

Trouble with installing 10.5 from an external firewire drive

I have a family pack of 10.5 and installed it just fine on my macbook. But, I'm having trouble getting my imac DVD player to read the DVD. It just spins and spits it out, and spins and spits it out. The imac is not covered under applecare so spending money to get the DVD drive fixed (which I barely use) is not something I want to do right now.
Anyway, I followed instructions on a this website to install 10.5 from an external firewire drive. (http://iuseapple.com/blog/apple-how-to/advanced-os-x/2007/10/29/how-to-install-l eopard-from-external-firewire-hard-drive/)
But I get stuck and am not able to actually get my imac to boot from the installer. Basically, I am able to use disk utility to create a copy of the disk image on my macbook. That resulting file ends in ".cdr" and it mounts when I double click it.
And I partitioned my firewire hard drive without problems.
I think I'm messing up when it comes to doing the restore. If I try to drag the .dmg mounted file in to the "source" it doesn't work (is greyed out). If I try to drag the mounted .dmg there than it works, but I get an error when I click "restore" (something about scans and images not being found). I tried physically copying the .dmg file onto the partition, but then when I plugged the HD into my imac, I wasn't able to get the imac to boot from the installer.
What am I doing wrong? If someone could walk me through these last steps I'd appreciate it!

Okay I finally got around to creating the bootable disk image of 10.5 using Carbon Copy Cloner. Still my iMac is not booting from the firewire drive!
Here's a recap of everything I've tried. I'm at a complete loss now!
- I partitioned the HD into 2 partitions-- a 10gig one for the 10.5 install, the then the rest for Time Machine. I make the partition in Disk Utility on my MacBook.
- I've partitioned the drive a few times-- always partitioning it in APM format (b/c it needs to boot my non-intel iMac).
- I've created the disk image using "restore" in disk utility. I've again tried this a few times.
- I am able to boot my MacBook from the disk image I create! So I know the FW drive is able to be used to boot from!
- Here's what I've tried in terms of getting the iMac to boot from the FW drive. It always just boots to my internal drive instead. Sometimes I briefly see a folder and question mark. I've tried all 3 FW ports. I've selected the install partition at start up in preferences. I've also held down the option key at start up (only my internal drive shows) and I've held down command-option-shift-delete and again I get the question mark and it boots to my internal drive.
- And I installed Carbon Copy Cloner and made the disk image that way on my macbook. Still, I tried everything and the iMac is not able to boot from the firewire drive!
Since my DVD drive is broken, this is the only way for me to install 10.5! Help!

Is it possible to boot windows solely from an external hard drive so that it does not affect the internal drive

Is it possible to boot windows solely from an external hard drive so that it does not affect the internal drive. I already know that you can partition the internal hard drive to do the very same. Idon't want to use any of the internal space to run windows so I'm asking if it is possible to use a flash drive or external drive through USB to run windows when it is plugged in.

Is it possible to boot a G4 (pci graphics) from an external firewire drive?

I have a Lacie 250 gig bootable external firewire drive which is recognized on my Power PC G4 400 but I cannot get it to boot from this drive. The procedure works fine on my ibook... I looked into a possible firmware update but the apple site says no update is necessary for the G4 400/pci graphics...
Any suggestions?

There sure are some radically contradictory posts here! (This isn't typical, at least in this section of the Discussions, RMx2.)
Can anyone who has posted here (or might join in here) actually boot from a hard drive connected via USB? I just tested this with OS X and I can't. For some time now, the Discussions have been riddled with posts, whether 100% accurate or inaccurate, that Macs don't boot from USB drives, despite the seemingly conflicting info in the article that Don kindly referenced. (John Huber: Don't eat your words just yet, John!)
Here's my personal experience, for what it's worth... I have a rev.2 B&W G3 which recognizes, reads, and writes to drives via USB, but refuses to boot from them (I tested with OS X 10.3 and 10.4). I also have a QS 2002 G4 that yields the same results. The QS G4 will, however, boot from these drives via FW. I used a WiebeTech ComboDock for testing this with both USB and FW. I tested with two different hard drives, both of which are known to have stable, working versions of OS X on them.
My G3 running OS X 10.3.9 sees the USB-connected drives in the Startup Disk Preference Pane, but when I click to Restart after selecting the USB system folder there, I get a beachball (haven't seen that in awhile...) and have to Force Quit System Preferences. Console tells me that that it could not get open firmware information or set open firmware information, and that it can't touch or set System/Library/CoreServices/BootX, returning Error 1 running bless.
On the QS running Tiger, the USB OSs don't even appear in the Startup Disk Pane of Sys Prefs. I can see the USB drive(s) using the Startup Manager, but selecting them and restarting results in a hung startup to a spinning cog with a prohibitory sign on the screen...
I haven't tried playing around with open firmware NVRAM settings (and don't intend to, except perhaps for trying an NVRAM reset), nor have I attempted to boot to OS 9, reset the startup disk there, and attempt the boot again to the USB device in OS X and in OS 9, which I may try later on when I have a bit of time...

Can I boot my F30 from an external floppy drive?

I use Norton Ghost to clone a copy of my harddrive on my PC for use in disaster recovery and it requires a m/c boot from a floppy hard drive when I use Ghost. I want to do the same on my F30 but have no idea if I can can configure the F30 to boot from an external floppy drive. If it is possible can somebody please tell me how to change the boot sequence as I have no experience whatsover of laptops. Many thanks.

Hello
I use Norton Ghost 2003 and I am very satisfied with it. It runs under windows and you can create image file on second partition or even create recovery DVD immediately without using floppy disc. I can just recommend it to you.
Back to your question: with your Qosmio model you can use floppy drive with follow part number PA3109U-3FDD. If I am remember well you can press U button just after switching the unit ON and the unit should boot using floppy drive as first booting device.

Booting from an external firewire drive

I bought an external hard drive (Western Digital, 320 gb, firewire). First, I erased the disk and formatted it as Mac Os Extended (Journaled).
I cloned my internal drive (using SuperDuper) on to the new external drive. My goal is to have an alternate bootable drive in case my internal drive fails. However, it will not boot on it even though it may be selected as the startup disk. And will not come up as an option when holding down the option key while booting. I've read about a similar problem that was posted but the solution confused me. Can you give me a solution to this problem?

First you should prep the drive correctly as follows:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, select the button for Zero Data (single pass) and click on OK to return to the Erase window.
6. Click on the Erase button. The format process may take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
After formatting has completed select the volume you must created from the left side list, then click on the Restore tab in the DU main window. Drag the new volume to the Destination field. Drag your startup volume from the left side list to the Source field. Click on the Restore button.
After cloning has completed quit DU. Open Startup Disk preferences, select the new volume and click on the Restart button. Your computer should boot from the external drive.

Can I boot from an external Firewire drive?

I have restored my internal system drive (27GB) to a 100GB partition on a 300GB external FW drive (as a backup).
Using System preferences I changed the startup disk to be the clone & rebooted to test.
No start and the only way to get going again was to turn the FW drive off & reboot.
Is it possible to boot from a FW drive?
Should a drive as described be bootable?
Any thoughts will be appreciated.
John

Thank you all for your input.
After some trial & error (& little sleep last night) I have made some progress:
Further research suggested that:
1. there may be a hardware issue with my Ex FW case (it has a Prolific PL-3507 chip)
2. Tiger (10.4.x) behaves differently from Panther (10.3.x) and possibly different versions of Tiger may behave differently
Also I have previously successfully used DU to move my OS from a 30GB to 120GB disk (both internal drives) under 10.3.9. This disk will boot when placed in a ext FW case.
I concluded that under 10.3.9 at least my case was OK & Apple DU was OK when run from the boot volume.
I also checked the clone made using DU under 10.4.3 by taking the HDD out of the FW case & installing it internally in my Mac - it wouldn't boot so DU hadn't made a bootable clone - it was never going to boot internally or externally. Ever.
Next step - SuperDuper! - worked perfectly - backed up & booted no fuss, no worries.
This confirms that the Prolific PL-3507 chip will boot an external FW disk under OS X 10.4.3.
I then referred to Lee Cullens' posts as quoted by Matthew Whiting (with a link above in this topic).
Lee has the answer (at least for my hardware/software configuration). For Apple's DU to produce a bootable clone it cannot be run from the disk which is being cloned (ie 3 volumes are needed
1st to boot from & run DU from
2nd to be cloned (the vloume to be backed up)
3rd to be colned onto - the backup
I tried DU from the boot disk again to "prove" it wouldn't work. While it appeared to clone correctly Permissions were all messed up & after over an hour of "Repairing Permissions" I gave up. The volume wouldn't boot even though system preferences saw it as a bootable volume.
I then ran DU from another volume (the one made using SuperDuper!). After verification (but not repairing permissions as I didn't want to potentially waste another hour!) it booted fine from the ext FW drive. I did however uncheck "Ignore Ownership" after Cmd-I on the volume from the desktop.
I conclude:
My hardware is OK (& probably others who may have similar issues)
Apple DU can make a bootable clone which will work on an ext FW drive PROVIDING 3 volumes are used - boot with DU on, from & to. Suitable for a bootable backup but a bit fiddly ( also free & regularly updated by Apple)
SuperDuper does the same job with less fuss (don't need a CD or 3rd volume + other features). As noted by Matthew basic cloning is free but I think the shareware cost will be worthwhile ($US27.95)
SuperDuper! here: http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
Thanks to all for their input.
I now have an answer that I'm more than happy with.

Can the iMac G3 with Panther boot from an external FireWire drive?

It does have firewire. I am worried that if my internal HD fails, I am going to be SOL. Sooo... If I install just Panther (full retail) on a new internal HD, will i be able to boot from it? How about if it is on an external FW drive? I DO NOT have the original install disks that came with the computer.

If I install just Panther (full retail) on a new internal HD, will i be able to boot from it?
Yes. Verify that the computer's firmware is up to date first.
How about if it is on an external FW drive?
Yes.

Can the new Mac Mini boot Snow Leopard from an external hard drive?

I currently boot my 2009 Mac Mini from a FW800 external drive with 10.6.8. If I just plug my external drive into a new 2011 Mac Mini, will it boot into Snow Leopard if I set it as the startup disk or will I get a kernel panic?

I bought a 2011 Mac Mini, which came with Lion installed. I thought maybe I could repartition it and have a Snow Leopard partition. So I repartitioned it (500gb split into two 250gb partitions). I named the new partition "SnowLeopard" just to make it easy for me to tell the difference.
I attached the external DVD and put in a Snow Leopard installer disc, holding down the C key so it would boot and install from that, but it just spun for awhile. Doesn't appear to work.
Then I read somewhere else that someone had managed to clone a copy of Snow Leopard onto an external drive and boot from that. In their situation they were talking about a MacBook, but the principle seemed sane.
So I rebooted, holding down the T key to put the Mac Mini into Target hard disk mode, and attached it via Firewire to another MacMini (circa 2008 or so, not sure of year, but it was upgraded last year to Snow Leopard and has been upgraded along and along). Then I used Carbon Copy Cloner to copy Snow Leopard (that is, the entire hard disk-- System and all applications and data) to my newer Mac Mini's "snow leopard" partition.
For yucks, when it was done cloning, I restarted the older Mac Mini, and had it boot from the newer Mac Mini's snow leopard partition--- it worked! To make it easy to tell the difference, I changed the desktop background to something completely different. I think I tried booting from Lion but I can't remember if that worked.
Then I rebooted the newer Mac Mini, which booted up in Lion, of course. Going into System Settings, I changed the startup disk to the "snow leopard" partition, and rebooted, and it booted up in Snow Leopard.
I have yet to test the applications on the Snow Leopard partition. Another problem has arisen.
Because with both of the Mac MInis being active on the network, they both had the same computer and user name. So I renamed the newer Mac Mini to something completely different, and changed the password.
Unfortunately, now I cannot change any other setting in the System Settings that requires a password. While the newer Snow Leopard lets me log in with the new user and new password, whenever I try to click the "lock" icon to change something, I'm prompted for a username and password. Apparently this is some different username and password than either the new or old username/password.
I've tried various combinations of both: new user/old password, old user/new password, old user/old password, etc.
So if you do what I've done, be careful about changing the username and password on your cloned computer. I think it may be wiser to create a new user and then delete the old cloned users. I may just have to re-clone the old Mac Mini to the new one again.
If anyone has any ideas about this password conundrum, please pass along!

Can I boot 10.5 from an external hard drive?

Hi Folks,
I thought I was able to create a bootable external firewire hard drive containing Mac OS X 10.5 but having no luck. I would like to be able to test some legacy software on it and cannot get it to even boot. I have an 80 GB external drive with 2 partitions (8GB and the rest storage); GUID partition. The 8GB portion has the 10.5 installer I created from an install DVD.
I followed all the instructions but it doesn't seem to work from my Yosemite MacBook Pro 10.10.2 (2.5 intel core i5). Is it not possible because of Yosemite already being installed and it doesn't like I am trying to boot an early version of Mac OS X? Thanks for the help!

Unless this is some super special printer that has no modern equivalent you may want to reconsider. I haven't run things in server software but sometimes hardware can be picky and too much translation from Leopard to Yosemite (since you do have to run a Yosemite controlled cable out of the computer) will end up losing too much. I guess if you're the kind of person who loves trying to make this kind of thing work then fine, but if the bottom line is you need a printer you can pick one up in less time than it will take fiddling around, and not much more cost.
Thanks for the advice - yes I am going to have to fiddle. Good to know that there is a 10.5 server option but I think I will do an install of 10.5 on another older laptop or just go the windows pc route.

Can you boot a MacBookPro from an external hard drive with Windows XP?

I'm planning on getting a MacBookPro with a 512GB Solid State drive.
Is there any chance I would be able to find a way to boot from an external drive that has Windows XP installed.
Why would I want to do that you ask? I want to travel with my Mac, but have access to certain programs(AutoCad2010 & 3dMax)that are supplied on my Employer supplied computer without carting it around too... it's a "brick." I know there are Mac versions of AutoCad and 3Dmax, but my employer won't supply me with them. (They are not smart enough to recognize the productivity benifits of Macs.) I thought it would be great to take the Hard drive, put it in a USB or Firewire case and just boot up from that. Probably just a crazy idea, but maybe some clever person knows a way?

Windows XP will neither install nor run on an external drive. However, your boot volume is more than large enough to accommodate a Boot Camp partition in which to run Windows. Or you can purchase Parallels or VM Fusion to run Windows in a virtual machine. Problem solved.

Trouble booting my eMac from an external hard drive

My poor eMac's hard drive finally gave up the ghost the other night and died. My brother attempted to load OS 10.4 onto my external hard drive (Western Digital 320 GB My Book, Studio Edition) so that I could boot the computer up from there for the time being, but soon discovered that while my external can be used as a bootable drive from an Intel Mac, my Power PC was not supported.
Would another external hard drive, such as the LaCie d2 Quadra Hard Drive, boot from my PPC eMac? I found this note in the product description and want to make sure my computer is capable of this:
+** Bootable on PC or Mac (using FireWire or eSATA). To take advantage of the bootable feature, the LaCie d2 Quadra must be formatted as a bootable drive in accordance with the operating system being used. The computer must include a BIOS or an interface card that supports bootable functionality with an external hard drive.+
If so, I am going to try to ask the Apple Store to exchange my WD external for one that will (it's new, but just past the return date) so I can do this.
Yes, I'm sure it would be easier to just buy a new computer! Thank you for any help you can give!

He's taken the original iMacs apart to access their hds and doesn't relish dealing with that again. On top of that, I can't help but think that spending at least $200 on parts and service on a 6-year-old computer is really that worth it. It'd have a new internal hd, but old and busted processor and everything else. That's why I was aiming for an external set up.
Kitty,
I should have guessed the hd was failing, but didn't think about it.
I run S.M.A.R.T. Reporter on all my machines:
http://www.versiontracker.com/dyn/moreinfo/macosx/23232
What I need is to know if I'm going to run into this problem with most externals, or is it just the WD that cannot boot from a PPC.
Well like I say I've had two and both boot. I can't say I've ever had a problem with any firewire external.
I see some one else is having the same problem with that drive. Re:
Topic : Trouble accessing Western Digital My Book External Hard Drive
in this same forum.
I realize this would be a sticking point with the store and will totally understand if they tell me "too bad." If the store won't be really nice and help me out, I'll probably just take my lumps and buy a new computer. It was going to happen eventually, I'm just miserly with my money
Well see if you can talk your brother into doing the job. It's a bit harder than the old iMacs (That I can do in about 4 minutes - I even use my power screw driver ). If you email me I can send you instructions.
Too bad you're not near Chicago. I repair and donate Macs to schools in the inner city here.

Can I boot Vista OS from an external USB drive

Hi, I would like to install Vista onto an external (USB) drive and boot from that occasionally whilst retaining XP on the internal drive. Is this possible please. I realise I would need to change the boot order in BIOS.
I know I could create a dual boot internal but would like to retain as much space as possible on the internal drive as I will only rarely need to use the dreaded Vista.
Thanks
Ron

And how you want to install Vista on USB device? Have you already tried it?
Please post a little bit about your experience with it if you have some.
Anyway, as far as I know something like this is not possible.
