Incomplete booting from ext FW HD on intel iMac.

I have recently upgraded from my G5 desktop to a new iMac 2.4 model. After transferring the data, etc across I wanted to create a clone by backing up onto an External Firewire Drive, just as I had been regularly doing with the G5. Initially I used the disc utility and later in the >partion> options switched from APM to GPT, proceeded to clone using SuperDuper! In both partion modes the startup disc looked happy to boot from the FW disc and indeed seemed to boot from it.
I thought task done when asked for the login name, HOWEVER, this was followed by the desktop screen and the "Blue Spotlight" in the corner. There it just froze! There is no other info on the menu bar and nothing loads on the desktop. There was also another 10 seconds or so of ext HD activity.
I use "Ice Cube" enclosures, gen 1 & 2, and neither FW800 or FW400 seems to make a difference. This PATA drive has never previously caused me any problems especially with SuperDuper! backup's.
What am I missing? Could somebody please help?

Not perhaps the best forum for your issue. You have posted this in the section specifically for dealing with iMac displays, which does not sound like it is your problem.
Perhaps posting in the 'Using you iMac' section might be better.

Booting from external hard drive on intel-based MacBook Pro

Good day everyone. I know similar questions were raised in this community, but I still have some questions.
I have MacBook Pro(late 2011) with OS X 10.7.5 and external hard drive with Ubuntu 13.04, from wich i can boot succefully on my PC. But MacBook Pro will not boot from my external drive, no matter which key/combination i use during restart.
After googling I found some answers to my initial question, how to boot from external hard drive
https://discussions.apple.com/thread/1852633?start=0&tstart=0
http://www.everymac.com/systems/apple/macbook_pro/faq/macbook-pro-boot-from-exte rnal-firewire-or-usb-drive.html
http://support.apple.com/kb/ht1948
As I understand I need to format my external hard drive into GUID partition type and this will be enough to be able to boot from it on my mac?
With this new partition type, will I be able to install ubuntu again on my external drive?
Does GUID partition type supports NTFS, ext4 and FAT32, linux swap?(I use ntfs for big files, ext4 as partition for ubuntu and fat32, because i use windows, linux and osx)
Will I be able to boot from my pc from my external drive with this new partition type?
What are downsides, if any, to GPT?
here is info on my e-drive

LowLuster wrote:
The only OS that will boot from an external drive is Mac OS X or maybe Linux. For OS X to be installed on any drive it need to be formatted Mac OS Extended and have GUID partition table.
As for Linux I'm not that familiar with it but again for a Mac to boot it need an EFI partition on the drive and I don't think that is possible with NTFS or FAT32 let alone the native Linux format.
Went to wiki to learn more on efi but found artice on uefi.
Operating system loaders are a class of the UEFI applications. As such, they are stored as files on a file system that can be accessed by the firmware, called EFI System partition (ESP). Supported file systems include FAT32, FAT16 and FAT12, and supported partition table scheme is GPT only. UEFI does not rely on a boot sector, although ESP provides space for it as part of the backwards compatibility.[26]
Here is FAQ on official uefi website.
Can UEFI Secure Boot be adopted and implemented by a variety of operating systems?
UEFI specifications are platform-independent, supporting multiple platforms and architectures. In addition, UEFI specifications are designed to promote cross-functionality, as well as to support broad adoption across multiple operating systems, including Windows as well as Linux-based operating systems. The specifications are robust and can potentially complement—or even advance—other distributions, such as Linux-based distributions.
And here is wiki article on GPT expaining OS support.
It is obvious both uefi and GPT are ok with Linux and file systems such as FAT32, ext4 and NTFS.
I guess there is no much difference(or is that the same thing?) between uefi and efi used in Macs.
In your answer to Stark Industries you said that mac can boot linux from external hard drive, well this is not the info i got of official website and it is still my question, because your answer is very inconclusive and your info is partially incorrect

No internal HD showing in iBook. Only boots from Ext HD or CD.

I think my hard drive packed it in. When I boot up I get a folder icon with a flashing ? on the screen.
A number of months ago I made a duplicate of my internal drive on an external HD with carbon cloner. Fortunately it made a useable boot copy which I'm using to boot the computer. I could not previously boot from the external HD so I didn't know if this was going to boot. But it did!
I tried running Techtool Pro but it locks up so I can't check any hardware. Disk util used to allow me to click on verify permissions but would then give an error and refuse to do anything. Now it doesn't even list the internal hard drive. Computer seems to run normally from the ext. HD. Sometimes when booting the computer I will hear a faint moaning sound in the laptop until it starts booting from the Ext HD. So I'm pretty sure the drive is shot. There was no warning to indicate any hard drive problems.
Is there anyway to do any hardware testing to determine if its only the hard drive or something else that's shot? Why would techtool not complete the first step of hardware testing (memory) at the beginning of the test? Is there a way to make it run so I can check the hardware? I've tried deselecting all and trying to run tests other than the hard drive ones but nothing happens once it starts the test. Is it because it had to use the internal hard drive to start the tests?
The computer is still under extended warranty but I can't find the apple web page link to check when I bought the computer. Yesterday I could find the link for my remaining warranty info but today I can't find it. Where is this link hidden?
I have also tried and tried to find a link in support to request a hardware repair but such an options seems to be non-existent. Is this possible?

One thing you can do is to run the Apple Hardware Test, which is on one of the gray CD's that originally came with your computer. It may be a separate disc or on one of the install discs. You should get one or more error codes which will indicate where the problem lies. You can then call Apple Technical Support on the telephone and give them the error code, which they can interpret. If you are under warranty, they will probably want you to send it in for warranty repair. They can also tell you how much time is left on your warranty. If you are at all close to the end of the warranty period, be sure and ask for a case number, which will document that the problem first occurred under warranty. This is important to do, because they will honor the warranty until the problem is fixed as long as you can show that it first occurred under warranty.
Good luck!

Booting from Ext HDD / SSH / Codecs question

As I understand it, there are two things you can do to the apple TV.
1. Boot from a regular mac os x install on an external HDD from the USB port
2. Take the HDD out, enable SSH / install codecs, etcs
My question is quite simple then:
Is it possible to boot from the ext HDD and then install perian / flip4mac components and enable SSH without opening up the Apple TV?
From my understanding of the above, logic says, "yes"
Regards
Paul

As I understand it, there are two things you can do to the apple TV.
1. Boot from a regular mac os x install on an external HDD from the USB port
I doubt this is possible, besides a number of issues that you may or may not be able to resolve in instructing the tv to boot from another SUD, I doubt the tv has the ability to run a regular OS anyway (RAM limitations etc) but that is just my opinion, I have no specs to support this.

Late 2012 Mini won't boot from ext HDD with 10.8

Having just replaced an early 2009 Mini with a later 2012 mini, I tried booting off an external HDD that is a backup with Mountain Lion 10.8 as the OS. I selected it to be the boot drive after holding down the option key, but the boot process never went beyond the white screen/Apple logo, even after waiting for minutes.
The external drive is in a Newer 3.5" enclosure with a FW800 port connected to the Mini via a FW800 cable. After booting from the internal drive I can view and change items in the 10.8 external drive. This drive previously booted fine from my old Mini.
[Note: This is not related to my earlier "Snow Leo won't boot" question.]
Thanks

The problem is the version on the external drive, if created
on the old Mini (infered from ""This drive previously booted
fine from my old Mini.") won't boot on the new Mini because
it lacks drivers that are not available on the general Mountain Lion
updates. Since the new Mini came out after 10.8.2, only the
version on it contains the proper drivers. Also, if the version
on the external drive is earlier than 10.8.2, it will never boot
as no Mac can boot to an OS older than it was shipped with.
Whenever 10.8.3 comes out, it will likely sync all current models again.

Thunderbold boot from ext vs internal 7200

Is if faster to boot from a Thunderbold drive than It would be to boot from a 7200 2.5 internal?
Would you notice a big difference in you performance in logic pro and in general ?

Well, I was able to get down to my vendor and spent the entire morning cloning the Mac mini to the Backup Drive... Phew they haven't start work on the Mac mini yet.
But here's the "mysterious thing":
I mounted the Backup Drive which is supposed to be corrupted or something, use Mac mini's Disk Utility to erase and reformat the backup disk, check again and everything is fine.
Use SuperDuper to clone the drive.
After that, I use Disk Utility to check the Clone Backup Drive and it return some sort of error in red, that the disk cannot be repaired, but this time it is mountable.
This lead me to conclude that either
-the Mac mini itself might have some OS system error corruption something that was cloned to the Backup, hence the error message in Disk Utility, because before the cloning the Backup Disk was perfectly OK, according to DU
and/or
-The Backup disk itself is faulty, easily done as I can just replace a new hard disk
What is your comment, opinion?
Anyway, I've reached my office and just in case, I am copying all the Users' data (not clone) to another disk, back up of a back up.
And when the Mac mini is back I will re-install/re-format etc a fresh new OS, and just copy over the data files; Then check the status of the Backup Drive.
Cheers

Startup Manager arrows but no drives (trying to boot from ext

Today my old eMac (ppc 10.4.11) that I will replace soon froze up and will boot only to a grey screen. I tried safe-boot and pram reset to no avail. I had earlier made a clone of the eMac drive* and would like to boot from that (via firewire). I option start up I'll get to the blue Startup Manager with the 2 arrows, a spinning wristwatch but no drive icon. Eventually the wristwatch stops spinning.
I also tried to hook up a stand-alone dvd drive** (tried the firewire 1st, then the USB port)port) with the original eMac install dvd but get the same result as the external boot clone. (arrows, a spinning wristwatch but no drive icon.)
Any ideas on what to do to revive this eMac before I toss it out?
Thanks in advance,
Paul
*This clone is old-ish, I think I'm pretty well backed up on recent files but would really like to do another review before I throw the eMac in the garbage.
**Don't know how to force open the dvd tray

Hold Mouse button down at boot to open the tray.
Seems the internal drive is bad & likely preventing recognizing the FW drive, but is the FW drive spinning up? try hitting the 3/4 circle arrow to have it look again for drives.

Cannot boot from ext drive after 10.5.2 update

I followed the procedure in tech article 306502 for creating and updating a bootable drive. I am in a PPC Mini environment. External drive is LaCie 160 GB rugged firewire portable with auxiliary power, I created the drive with 10.5.1 and it booted nicely to my two Minis (running 10.3.9 and 10.5.1). I then updated the external system with 10.5.2 from the Apple site and now it does not boot. Sits and spins with a white screen, grey apple, and whirligig. Whirled for 1/2 hour and tried deveral times.
I see this is not uncommon, but there have been no cures posted. One post suggested Disk Warrior. What would I do to with DW to move this problem forward. This is quite annoying, as I rely on being able to move around and boot from this drive when needed.
Thanks for any help.
Fred

after 10.5.2 two days ago, mine booted up regularly. however after the additional leopard graphics update last night, it no longer boots up at all. i have to usethis ****** vista to report the problem. my macbook is right beside me, with nothing but a plain blue screen. occasionaly the mouse cursor appears for about 30 seconds, then dissapears and the screen remains blue. what can i do? if i cant log in apple cant update my mac!!! help!!!

Importing video from Samsung a707 to new Intel iMac

I've got a new Intel iMac with 3 GB RAM, 500 GB HD, and the Nvidia 256 graphics card... and I've just upgraded my cell phone to a Samsung a707, which has a 2 mp chip, and accepts microSD memory cards. With a 1 GB memory chip, it's supposed to be able to take about a one hour video. I can't find a firewire microSD card reader that would let me import the phone's videos into my iMac. It comes with an SD adaptor, so I could use a firewire SD memory reader too, I think. Does anybody have any suggestions about how I can get the videos on the microSD memory card into my iMac, and then edit them with iMovie?
Thanks for your help!
Tim

Your problems may well be down to the way you connect your camera and in which order you establish a connection. If all else fails voltaic will get the files from your camera in AIC which will readily be imported into im08 for editing.

Migrating from 1.25Ghz G4 to Intel iMac problem

Hi there!
Question in brief:
Can I install old (non-universal) software (such as IDCS2 and Qk6.5) on a new Intel iMac?
Question at length:
Just got a new iMac here, and wanteed to do a migration (which I've done problem-free between PCC Macs) and have hit upon a problem. The new iMac will not see the old Mac (connections/cables/old mac have been tested). New man just says "Waiting for your old mac to restart"
I came here looking for an answer, and fount this post
http://discussions.apple.com/thread.jspa?messageID=4753948&#4753948
So it looks like it's going to be a LONG job. Can I just reinstall non-universal 3rd party apps from original CDs? We have NO universal software at all.
Thanks for your help.

Hi Kappy
Thanks for your reply. Sorry for not being clear enough – ou see I'm not exactly sure of what migration assistant is capable of.
I know that when you connect the two macs MA Upon start up (Migration Assistant) can copy the user settings. I presumed it could do this because it was copying over the newer mac's user settings at a point where the newer mac a total access to the drive. I therefore presumed that if (instead) the iMac had been started up, and then I ran MA, it would not be able to replace the user data, because it is in use.
That link I put in the original post said that I shouldn't do applications via MA from a PPC to an Intel one. So I'll have to reinstall those from the original disks. That's O.K., right?
Thanks again ;0)

Problems backing up then booting from a firewire drive on Intel Macs

Hi
I wanted to help a friend back up his Macbook and then install Bootcamp.
I took over my trusty external firewire drive (Makeytec MHD-25 Combo enclosure + Samsung 80Gb HDD).
So... I ran Disk Utility
Highlighted the firewire drive, clicked Partitions, named it "Backup". Clicked Options -> GUID -> Partition
I backed up his computer with SuperDuper onto Backup. SuperDuper automatically makes the drive bootable. At the end Backup was mounted on the desktop and all files are there.
But Backup wouldn't boot the computer. Instead I got a grey screen for a long time, then the Apple logo with the spinning cog, then after a few more minutes a circle with a bar through it (like a no smoking sign minus the cigarette)
Things I tried after this....
Partitioned the drive again, double checking that I had selected GUID
Erased the drive zeroing out all the data
Backing up using CCC (with make drive bootable option checked) instead of SuperDuper
Could not get this drive to boot his computer.
Then took the drive back home. Tried doing it with my MacMini (same problem)
Then plugged it into my Powerbook, Partitioned it as Apple Partition Map, ran SuperDuper, rebooted from it fine.
My conclusion: The drive will boot a G4 just fine, but not an Intel based Mac.
Does anyone have any suggestions?

A workaround:
The drive enclosure also has support for USB "1.1/2.0", including the ever important cable.
I reconnected it to the Macbook, partitioned the drive back to GUID, then I used super duper to back the Macbook drive (again!). I used firewire (only because it was much quicker - 6Mb/s vs 2.8Mb/s)
Once I did the backup, I ejected the external drive, disconnected it, then plugged it back in with USB, then selected it as the start up disk, then hit restart. Machine rebooted just fine although very slowly.
Still doesn't answer the question of why booting via the firewire port works fine with a G4 mac but not Intel.

Portege 3490CT - please help me to boot from ext CD

Hello from Maine, USA.
I bought the 3490ct and a TDK brand USB CD-ROM drive. The 3490ct came with a formatted hard drive. I would like to boot my OS CD with the USB CD-ROM and get this computer running.
Can it be done? Do I need to get the port replicator and floppy drive?
I tried opneing the computer up to remove the hard rive and put the files on manually but it looks difficult to remove and I don't want to ruin anything (it's surrounded by those tiny cables that are hard to work with)
Help! How can I get an OS onto this thing!
Thank you,
Craig

OK,
I have the port replicator and the unit with nothing but command.com on it, I have no drives.
Can I send data to it's hard drive via the network? If not can I send data to the hard drive with a PCMCIA hard drive?
I don't have a PCMCIA hard drive but am willing to get one...
How can I get data to this unit's hard drive?
Thank you,
Craig

Booting from ext drive

I used Super duper to make a backup on a estata drive. when starting MacBook pro how do I tell it to book from there. What is the key command etc...

> Yes I know that but what if my regular boot drive is down, corupted, etc... and will not boot?
Use Apple/Option at startup and it will find any available Boot volume
> For my processor intense stuff
It's not the processor really it's how fast it can write/read frames to/from the drive for stutter-free, high-res video capture/playback/editing. I've the opposite of your setup, internal is the fast 7200 100GB and the external 2.5" is a 5400 160GB (both Seagate). I only edit video on the internal and store/backup on the external.

First you say you have an iMac G4. Then at the end of your message you state specs that say Intel Core Duo.
I wish you would get your story straight because if it is an iMac G4 it can' have an Intel processor in it.
Once you get a plausible story, I'll consider answering you then.
