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

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!

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.

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.

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.

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!!!

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.

G5 won't boot from any drive (internal or external)

I've been studying this forum for the last several days, hoping to find something to help me solve the problem, but so far I'm still stuck.
Here's the deal...
I bought a refurbished G5 2.7DP (early 2005) from Apple's Online Store and got it about a week ago. I ran it awhile, the way it came... then I updated to OS X 10.4.4, installed some apps, set up everything and all was fine for several days.
Then, all of the sudden the mouse locked up and I had to power down with the button. When I tried to restart (and every time since), I power up, get to the gray screen with the apple, and that's as far as it goes.
After several minutes, the fans start winding up... but no matter how long I wait, it never proceeds (never gets to the spinning gear stage).
Internal HD, SuperDrive:
The first thing I tried was the G5 install disk, but it doesn't load.
I've tried starting with the option key down (numerous times) and the mounted volumes show up in the startup manager (internal HD, SuperDrive), but selecting either one gets me no further than the gray/apple screen.
I've tried the startup manager with a FireWire HD and my G4 in Target Mode (both with OS X 10.4.4) and they'll show up, but don't get me past the gray/apple screen.
I'm confident that the G5's drives are good, I've run Apple Hardware Test (from the G4's SuperDrive, targeting the G5) and no problems are found.
I eventually used the G4 to erase the Target G5's HD and installed a commercial Tiger system, to see if that would work (couldn't use the G5's installer disk, 'cause the G4 wasn't a G5). No better off than I was before.
I can boot the G4 from the Target G5's HD and it works fine... and the installer DVD (in the G5) also mounts and is accesable from the G4.
Anyhow.... as I said, I'm confidant that the G5's drives are working.
MEMORY:
The G5 came with 512 megs (2x256), then I added another gig I got from OWC.
During my troubleshooting process, I've removed the OWC memory and nothing changed. I then replaced the Apple memory and replaced it with the OWC memory. No change.
None of the memory tests I've run have indicated any problems, but I wanted to rule it out as the problem.
Yes, PRAM has been zapped and the PMU has been reset (both, several times in the last few days, just to make sure)
When I came to this forum to start doing research, I'd pretty much concluded that there's a missing link in the boot process...
I've read some threads about similar, but not the exact problem I'm having... and I've tried several of the Open Firmware instructions suggested to others (reset-all and a coupla others that I can't recall at the moment).
I have a one year warranty, but the last thing I wanna do is send back the Mac (and Apple doesn't like my state or they'd put an Apple Store here
I just feel that it's a firmware/software issue that I'd be able to fix myself, I just need a little help with the missing link to the boot process.
So.. somebody please tell me that there's a simple one line OF command that'll get this rascal to boot again (or whatever it takes).
Thanks... sorry my post is so lengthy, but wanted to get as much info in one post as I could so it wouldn't be bits and pieces scattered over numerous posts.
Any solutions much appreciated!

powermac dual 2.7 G5 Mac OS X (10.4)

I just remembered something that I meant to mention. When I startup the G5 with the option key down and the installer dvd in the superdrive, the startup manager will allow me to run Apple Hardware Test and the computer runs normally (fans don't go wild).

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 a flash drive

So I have a G4 that meets all the requirements for 10.5. I am currently running 10.4.11. I have a copy of 10.5 which is on a flash drive. I looked into it and followed the instructions on how to load from a flash drive. Reformatted to allow journaling and used disc utility to put the 10.5 installer on there bur when I hold option to try and boot from the drive the only possible drive to boot from is my internal hd. The flash drive doesn't come up as an option. Any ideas why?

Why rare when I can do it! All you have to do is type in open firmware the following:
boot ud:3,\\:tbxi or if you just have one USB device, type: boot ud:,\\:tbxi.
Works everytime, also works for flash drives and external optical drives hooked up to USB..
Only drawback: It won't appear as a start up disk under system preferences, I am trying to figure out how to hack it to make it recognize it. USB 2.0 booting on PowerPC was introduced silently with Tiger 10.4.3(from what I read).
for any powerpc mac, go into open firmware and type: devalias.. scroll until you see "ud"(your device needs to be hooked up for this to work). Then follow the instructions above.. You will be amazed to welcome USB as a new member of your powerpc bootable family.

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

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

G5 Tower won't boot from other hard drives

I have recently purchased a used G5 tower and cannot get it to boot from a second internal drive nor from external Firewire Drive - all running system 10.5.8. My G5's primary boot is a Western Digital Serial ATA on Bus A. On Bus B is a Samsung Serial ATA drive, and attached via FireWire is a Western Digital 1TB Mybook (with 3 partitions - one with system 10.5.8). When I go to System Prefs and choose Start-up disk, the Samsung on Bus B *does not appear* (although it shows up on my desktop). My FireWire WD shows as a Start-up drive, but when selected as my startup, and I reboot, the machine starts from the WD on Bus A again.
I've been with Macs ever since the 80's and served as system and network manager for all our units--installing, upgrading, and troubleshooting dozens of Macs in our unit. I'm now retired and this is the first time that I've encounter a problem like this. I've tried switching buses and jumpers but nothing seems to work.

Won't boot from install DVDs

I have an iMac here that refuses to boot from the install DVDs, no matter what.
I tried booting using the alt key, the C key, using the DVD in the Finder and restarting and via the startup disk in the System prefs. I always get one of the two following results: - either the DVD seems to startup, but then puts itself into a loop where it doesn't get to the installer and restarts the computer, - or it simply bypasses the DVD altogether and boots from the the internal hard disk...
I tried using various (full and legit) OS10.5 installation DVDs with the same results as above...
I've performed these operations many times in the past without problem, and It's actually the first I see a Mac that refuses to boot from an install DVD...
I thought maybe if firmware password protection enabled somehow... Would that do that?

You need an installation DVD to turn firmware protection off, ironically.
I doubt it is the issue here, though. If it was enabled, it would show a grey lock when you try to hold down option while booting up.
Is the iMac you are trying to boot from the DVD Leopard compatible as far as processor and RAM? My brother's iMac w/ 256 MB RAM cannot boot Leopard at all.
