Booting from a NTFS external HD?

Hey. I just got an external HD and I want to format it in NTFS format so that I can read it on Windows computers. But, would I be able to boot from it on my MacBook if it's in this format? It's only 60GB, so I don't have enough space to make multiple partitions in different formats. Also, are there any disadvantages of using a NTFS-format external HD on a mac (like slow performance or something like that)? Thanks for the help!

There's really two options:
Format the drive using FAT32, or install MacDrive on the windows machine and use HFS+.
Basically it comes down to this:
There's essentially three windows partition formats, all of which OS X can read.
They are
NTFS
FAT
FAT32
While it does make sense to use your windows machine to format the drive in NTFS, so it can read and write to it, it will not be a true drive on your mac, as OS X does not have the ability to write to a NTFS partition, it will be more like a CD or DVD.
If you format the drive using the disk utility on your mac, you can choose to format it using FAT32, which can be read and written to by both windows and OS X.
The downfall to FAT32, is the 4GB file size limit, and some limits on number of characters in a file name.
It's up to you which way you choose to go.
Either way though, you will not be able to boot from it, as the default startup for OS X recognizes very few formats.
Granted with the new Intel Macs, you can run windows on a partition on the internal drive, but Boot Camp doesn't allow installation of windows to an external partition

Hi, I have a hard disk failure so to recover my data I am using disk utility to restore the data on an external drive while booting from a second external hard drive. When I perform the operation it gives me an input/output error and stops. Any tips?

Hi, I have a hard disk failure so to recover my data I am using disk utility to restore the data on an external drive while booting from a second external hard drive. When I perform the operation and after having selected both my destination and source drives, the operation begins but soon fails due to input/output error. If I try to create an image of the drive it gives me the same error message. Any help would be much appreciated.

Disk Utility only creates a image of the drive, so it's no help getting exactly what you want, which is your files. If the file structure is messed up or the drive is failing then it's no help.
If you have a external boot drive and you can't access the internal non-booting drive though the typical Finder and windows to transfer your files via drag and drop methods, then you need to install Data Rescue on the external boot drive and it will do as best as it can to recover your files. (works on non-encrypted/non-Filevaulted drives only)

Are you sure you have hard drive failure, or that OS X isn't merely not booting?

Kernel panic when booting from DVD or external drive

Hey Folks,
I have a 13" MBP, seems to run fine for the most part.
However, I can't boot from DVDs or external hard drives. Disk Warrior, my and a tech support buddy of mine's OSX Snow Leopard DVDs, and external boot disks all cause a kernel panic when selected from the alternate boot menu when rebooting with alt.
The DVD/External spins up, the loading spinner goes for about 20-30 seconds, and then BAM - Kernel panic. I'd reinstall OSX... but I can't!
Any suggestions? I'd rather not send the computer to a tech for a week - I need it daily for work.

Other than that you will need a working DVD drive.

MBP 13' Won't boot from CD or external Drive

Recently my MBP 13 (newest version) occasionally crashes with the grey screen death which forces me to hard shut down. This led me to believe my directory may be corrupted so I tried to boot from my external OS X (Snow Leopard) with DiskWarrior installed to do the repair. Unfortunately, when the grey Apple logo shows up, the computer crashes again.
I tried again using original recovery CD to boot hoping to use Disk Utility, but it does the same thing where it crashes at the Apple logo.
I can't seem to figure out why. Anyone have experience with this issue? how do I resolve this issue???!
Thanks

This could be why it won't boot to it. It may not have the correct drivers to run the 13'. You really should have a clone of each Mac you own. Perfect for trouble shooting this type of thing. You can partition an external to have clones of several different Macs. I do that, plus I clone each to an extra internal on the desktop models.
However, if this have any impact it should've occurred in the past?
I think you just got lucky in the past.
I just spent 2 hrs re-installing OS X again and restoring. It's still doing the same thing. (It appears I can boot from the restore CD, but not external drive).
What install method did you use please?
If you can boot from the DVD, go to disk utility and see what your internal drives S.M.A.R.T. status is. Might as well run a Disk Repair while you are there.
Also, since you can boot from disks,
I would try running the extended version of your Apple Hardware Test.
It's not perfect but may flag something.
I'm assuming you can't boot from your DiskWarrior disk cause it's an older version that won't boot the new 13'?
That's the case for me and my MacBook. Since you can't boot to your bad clone, do you still have another Mac around? If so, you could boot in Target Disk Mode and use Diskwarrior from the other computer to try and repair the 13'.

Can't boot from DVD or external drive

Because of recent slow performance on my iMac G5 I ran disk utility and repaired permissions, then clicked Verify Disk. It reported minor errors in directory files and said I should repair them. I tried starting up from the MacOS X installation DVD, but I get a spinning beach ball and a symbol with a circle with a diagonal line through it (like a Do Not Enter sign). I had to unplug the computer to reboot.
Using another computer, I made a startup disk on an external hard drive and tried booting the iMac from that, but I get the same beach ball and symbol. Tried another OS X DVD with the same result.
I am able to boot from the internal hard drive only, but then I can't do a disk repair. I have already reset the PRAM, but that didn't help.
Any suggestions ??? Thanks.

I tried starting up from the MacOS X installation DVD, but my G5 still starts from the hard disk and I am therefore unable to repair rthe hard disk.
Can I create a new startup disk by copying my installation disk, leaving off the installation software, and then start my Mac using Option "C".
On my previous Macs I always used Norton Utilities to repair my disk and recover files - are ther any similar packages available for OS X (10.4.7)?

Can't boot from clone on external firewire 800 drive

Hello,
I have a 24" mid-2007 iMac 7,1 running Snow Leopard. I recently changed my set up to put a clean install of OS X 10.9.1 on a partition of an external SSD. I also moved the 10.6.8 start up system to a partition on the SSD. My internal iMac hard drive now has no system folder, only my data files. I have additional firewire drives for Time Machine, other data and media drives. Finally, I just bought a pair of 3TB drives that I partitioned into enough partitions to be able to clone both operating systems and all my data files for a rotating pair of offsite backups. All moving/cloning of drives was done with version 3.5.4 (Mavericks-compatible) of Carbon Copy Cloner.
I can boot from my external SSD (either Mavericks or Snow Leopard) fine and all external drives mount correctly in either case. After cloning all the partitions onto the backup drives, I tried to test the clones but I am not able to start up using either the Mavericks or the Snow Leopard clones when the backup external drive is connected via firewire 800. This is true whether I select the clone volumes in the Startup Disk preferences pane or hold down the option key during start up (note that the external drive with the clone partitions does not appear in the list of disk choices with the option key method). I get the "question mark in the folder" sign that the start up system is not being found.
I have changed the order in which the external drives are connected (normally the SSD is first in the chain), including trying when only the backup drive is connected directly to the iMac. I get the same result no matter what.
Curiously, the Mavericks and Snow Leopard boot clones start up via firewire 800 when the external backup drive is connected to my wife's 2009 13" Macbook Pro, indicating that the clones and the enclosure (an OWC Mercury Elite Pro quad interface, newer version with USB3) both support booting. Furthermore, if I connect the backup drive to my iMac using USB, the boot clones both work to start up the iMac.
This all points to an issue with the firewire bus failing to recognize the boot clones somehow during my iMac's start up process. I am rather puzzled about how to fix this.
I can get by booting via USB in an emergency but because my system is old, this is of course USB2 so its slow. If I had to use the clones to recover I'd rather be able to operate and restore at FW800 speeds.
If anyone has any ideas what might be going on, I'd appreciate hearing them.
Thanks in advance.

Did you ever get this resolved, Greg?

Cannot Boot from OSX on external firewire drive

I recently bought a seagate hardrive and installed it in an external firewire casing. I partitioned it into two partitions, and installed osx 10.4.10 on one of the partitions, the same as is running on my Ti Book.
I tried selecting the os on the firewire drive as the startup disk, but when i restart, after the grey screen i get the flashing question mark icon, until the mac recognises only the default osx on the internal drive and boots with that instead.
That not working, i created a clone of my startup disk using DejaVu in my system preferences and saved it on the other, empty partition on the external drive and tried booting from that.
On restarting, i get the grey screen once again as the backlight fires up, and nothing more. the screen remains grey without any further ado until i hold the power button and force it to turn off. then as i start it up again, up comes the flashing question mark icon followed by a boot from the internal drive.
Any Solutions on this?
Many Thanks, Neptune.

Hi Dale,
Whoops- everythings not as smooth as i thought it was!
since i restored my internal drive, a lot of things have been really messed up, starting with, for example, iTunes reverting to version 4 instead of 7. that wasnt a problem, i still had the 7 installer, and soon had my whole music library back again. but the computer appears to have a problem with the handling of graphics. the finder wont create previews of even simple jpeg images, nor will it for video. quicktime wont open any video file, i get some random error message which i cant remember stating it could not open the file. and if i view my finder window in grid icon view, the usual blue mac os desktop image that i keep as a background in the finder window isnt there, instead its pitch black. same goes for the slideshow feature in the application graphic converter, i can start a slideshow and it will scroll through the images, but every image will instead be completely black. there are no scroll bars in itunes. i can scroll down randomly by clicking where the scroll bar should be, but there is nothing visual there at all, no scroll bar, no arrows. when i connect my ipod, the main ipod window of itunes wont display any graphics either, be it the picture of the ipod or the capacity bar indicating usage of the drive for music, videos, data, etc. instead, fine print says something similar to 'cannot display image, quicktime and lzw tiff decompression plugin (?) required' I cant remember word for word what it says, dont quote me on that.
the computer also came to a dead freeze twice in ten minutes, i had to hold the power button down to get it to shut off.
im sure there are other issues too which i havent yet noticed, but even these, i havent the faintest clue what could be causing them!
do you?

Portege M200: Booting from SD to external hard drive

"M200 Recovery using Floppy or SD Card
Posted: 15-Aug-2005 10:36
I am posting this in the hope it will help others seeking to use the recovery CD/DVD but without a bootable CD drive. I would like to acknowledge the Toshiba forum of TabletPCBuzz.com
http://tabletpcbuzz.com/forum/topic.asp?TOPIC_ID=12414
for the inspiration of how it was done.
1. You will need a floppy drive or an SD card plus any type of CD drive. If your M200 is not working properly you will also need access to another computer to prepare the floppy disk.
2. You will need to download some software: IsoBuster
http://www.isobuster.com/
and WinImage
http://www.winimage.com/
or similar programs.
3. Put the Recovery CD into any computer and run IsoBuster. Click on Bootable CD on the left and then on the right you should see an .img file of size 1.41MB on the right. On my CD it's called Arnes Boot Record.img. Right click on it and extract the file. Close IsoBuster
4. Open WinImage and then File/Open this .img file. This will be your boot floppy with all the CD drivers you need. In Disk, ensure Use Floppy A: is ticked then Disk/Write Disk. Close WinImage
5. Connect floppy and CD drives to your M200, and boot up from the floppy. It will take some time to find the CD but it will and you will eventually get the recovery screen.
That's it! If don't have a floppy drive but have an SD card and a working M200 then Toshiba's SD card program will put the .img file onto the SD card and you can then boot from there.
There is a good chance this method will work for other Toshiba notebooks but I can't check this"
(author stephem)
This works!
What i would like to know is, is it possible to somehow boot of the SD and instead of the CD drive it finds my external ide to USB hard drive and boots off of the windows on that?
Thanks.

Hi there
I hope after long time you will end your problem. The compatible ODDs for your Portege M200 are:
1) Toshiba, PA3352E-SCD2, USB2.0 CD-RW/DVD-Rom Drive
2) Toshiba, PA3402E-1DV2, Rev.501, USB2.0 DVD Super Multi Drive,
3) Toshiba, PX1055E-1NST, (Freecom drive), with a PC Card (16bit), Cable II, PCMCIA,
4) Toshiba, PX1055E-1NST, (Freecom drive), with a CardBus, Cable II, CARD BUS
When you install recovery image be sure that external device has enough power supply. I recommend you to use AC power supply adapter for external ODD (if available).
I have also found info you can use:
a) Toshiba, PA3352E-SCD2, USB2.0 CD-RW/DVD-Rom Drive
b) Toshiba, PA3402E-1DV2, USB2.0 DVD Super Multi Drive
I hope you will find out which one is the best for you.
Good luck!

Mac Pro will not boot from cd or external drive

My Mac has an issue whith the boot drive, and I would like to format the drive and reinstall OS-X Mountain Lion and then use Time Machine to resore the Data. When I try to boot my Early 2009 Mac Pro (OS-X 10.8) using the option key, it loads the scrren that allows me to choose among the bootable drives. Once I choose either an external drive or CVD, it loads to the apple screen, stays there for about 5 minutes, then loads the OS on the main drive... Any ideas would be greatly appreciated.
Bill Mueller

At first I was just going to say it sounds like you have a bad optical drive, but then you had to go and say that it also won't boot from a HDD.
That just makes things a whole lot worse.
Start by removing the side cover and checking the RAM to see if any of the LEDs are lit up indicating bad RAM. Usually if there's any bad RAM found, it will just automatically disable that stick, but maybe yours isn't for some reason.
Look for any other LEDs that may be lit. Generally speaking, the only time you should see an LED (outside of the power LED) lit consistently is if there's a problem.
You should also see if you can get Apple Hardware Test to run, which may or may not find some problem.
But sorry to say, it's sounding very suspiciously like a bad logic board.
One other thing to try, is putting the SL drive into a different slot. So if you were putting it in slot 2, try slot 3 or 4. If you just have a bad SATA port, you might be able to just work around that until you get a new system.
If by chance this system is still under warranty, do not walk, do not pass go, do not collect $200, RUN to the nearest AASP or Apple store to make it THEIR problem to sort out.

New Unibody MBP won't boot from DVD or external drive, just loops

Hey
We bought a new Unibody MBP on Monday, and loaned it to our CTO for a presentation. Having got it back from him now I wanted to nuke the installation and put a fresh copy of leopard on it, so I dropped the DVD in the drive, powered down, and booted holding the "C" key.
I get the chime, screen lights up, thinks for a bit, and if you use your imagination you can almost hear the DVD spin up. Then the screen goes black, lights up, chime, thinks a bit, goes black, lights up, chime and so on
I've tried booting from an external bootable clone I created with CCC (firewire external HDD), and same symptoms.
I even tried swapping in a hard drive that I know has a working bootable copy of Leopard on it, and then all I get is the eternal cycle, without pressing any keys on startup.
I also tried holding down the Option (Alt) key on boot to get the boot device selector. This correctly identifies the various boot devices - the DVD, on-board HDD and external firewire drive (if connected), and lets you select them, tries to boot, thinks, black screen, screen lights up, chime, repeat cycle endlessly until extremely frustrated.
Is there a known cure for this or am I doomed to take the thing back to the Apple store on Monday?
Thanks
Konrad

That is not the reason it didn't work. Here is the actual clarity:
*A retail Leopard DVD should be able to boot a new Macbook Pro unibody.*
So you are saying even if the driver for the controller on which the DVD drive sits is not available in the Leopard DVD you are using because the hardware was not manufactured at the time the Leopard release on the DVD was made, the OS should magically just boot? How is that possible? Unibody MacBook Pros have entirely NEW AHCI chipset - for which there won't be any drivers on the older Leopard DVD and as such the DVD wont be detected once the OS on the DVD loads. In cases where the chipset used is same (as in previous generations of MBP) it will boot.
The key difference here is that if you used an older version, some new hardware may not be supported - however, the computer *should still boot from the DVD*, which is the subject of this discussion.
The OP said that his computer boots from the DVD that came with the computer - just not with the old retail Leopard DVD. Also - what should happen if the new hardware happens to be the controller on which the DVD drive is sitting? How will it be able to read the DVD? What about the graphics card? If the drivers on the old leopard disk do not recognize the new graphics card - how is the OS going to display on screen?
On my way home, I stopped at a Mac store and asked them to test this. They successfully booted a new Macbook Pro unibody from an older Leopard DVD. And this is why Apple is replacing my computer, because it is a hardware issue, not a software one.
Again - you fail to understand that whether or not the old DVD boots on a new machine all depends on how much hardware has changed and what hardware has changed. It may boot on some generation of machine because the basic chipset and graphics did not change or were handled generically by the drivers on the older DVD but it may totally refuse to boot on new gen machine which has totally different / incompatible hardware.
So your claim that any old Leopard DVD must continue to boot on any new machine is not really technically explainable.

Will Late 2013 iMac boot from Snow Leopard External Drive?

Hey gang-
Got a new late-2013 iMac for Christmas (yayyyy!!)
I plan on running Mavericks for day-to-day use, but there are a few old Power PC apps that I occasionally need to run. Does anyone know if the new iMacs will boot from an external drive running Snow Leopard? I have an external Firewire drive with Snow Leopard on it and I'm wondering if the new iMac will boot from it if needed.
Thanks!
Dave

Thanks gang. No worries- I keep an older Intel MacBook with Snow Leopard on it and I suppose it will do in a pinch.
Cheers!

Boot Camp: Macbook Pro 8,2 wont boot from USB or External CD Drive

Im pretty far into this process, and I have already jumped through a few hoops. I have replaced my Superdrive with a HD and am trying to install Boot Camp on a late 2011 Macbook Pro 8,2. I have gone in and edited the info.plist by taking out PRE which allowed me to make a USB Bootable drive with Windows 7 Ultimate on it. I also have the install DVD with a an activation key for that. I have partitioned my HD with 50 GB of space for Boot Camp and Windows and then it prompts me to restart. At this point the computer tries to boot into Windows installer but instead gives me " No Bootable Device - insert bootable CD and press any key..." I have tried restarting holding option with the external CD drive and USB drive plugged in, with just the USB drive plugged in, and with just the external CD drive plugged in. With the CD drive plugged in and by holding option I do get the option to boot from OSX, Recovery, Windows, and EFI boot (the last two have the icon of a disk.) When I click on windows it goes to the black screen with No Bootable Device.... and when I tried EFI boot it just sits there for a really long time and does nothing. Any help?
I have already had people tell me to re-install my superdrive and try but that was a tedious process and I'd rather not do that. Thanks in advance,

Meh, with the price they take for a drive in Denmark, I don't think it's worth it... They take around 160 $ for the drive (that's the cheapest MacBook drive I could find), and I am not even sure that's the one I need.

Help! Can't Boot from Internal or External HD

My Powerbook is almost 4 years old (purchased Oct 05). Last October, right before my AppleCare warranty expired, I sent it in for repairs. Apple outdid itself. They replaced the display, the logic board, the optical drive, the battery and the charger. I was a very happy camper! In March 09, I accidentally dropped my PowerBook on its edge. The display was damaged -- black "ink spots" appeared on all corners and other places. Because I was not ready to buy a new computer, I kept using it. But the damage in the display slowly kept spreading throughout the screen.
About four weeks ago, the screen damage spread to about 2/3rds of the screen. I no longer could use it. So I borrowed an old LCD display and used the VGA adapter that came with the PowerBook to hook it up to the display. This was working great up until a couple of days ago, when I tried to boot up and, nothing. The computer began to go through the start up process but then it froze. Nothing showed up on the external display. But after shutting down and booting up several times, I was able to get it to boot up completely.
Today, I have been working all day to get the PowerBook to boot up. No luck. It just starts, you hear the "tada" and then nothing. I even tried several times to boot up from my external firewire HD by pressing the option key while starting. I have a Super Duper Clone on the external HD. Nothing, I could boot up. I am at my wits end! I intend on buying a new MacBook Pro, but I can't for about 2-3 more weeks. I don't know if I have internal damage in the PowerBook or if these are issues related to the recent OS update.
Anyone, please help right away!!

Part of the problem is that I can't see anything on my display, so I have to rely on the external LCD display. When I boot up by pressing the option key, I here "tada." The tiny part of the PowerBook's display I can see lights up dark gray, and then nothing else happens. Nothing at all on the external screen. The same thing happens if I boot up in Safety Mode (by pressing the Shift Key). I tried booting up with my external firewire HD, as well as using my TechTool Pro CD, and the same thing happens. It seems the boot up process just stops. Now my TechTool Pro CD is in my PowerBook and I can't get it out.
Help! What should I do?

Boot from HP dv4t external HD

I just bought a 2.5 GHz macbook pro recently so I am still new to this. I'm switching from HP.
My problem is this:
I have a program "crack dat pat" that's locked onto my HP HD. Thus, I can't reformat the HD or transfer the program file onto another HD and run the program from there. My question is, if I convert the existing HP internal HD into an external HD, will I be able to boot from that external HD so I still have access to the program from my new macbook pro? Will I have to remove all the HP drivers on the HP HD first because they aren't compatible on a mac?

A Windows system from an HP cannot boot a Mac. Macs use a different operating system. If it's your intent to run Windows on the Mac you would need to install it via Boot Camp or through virtualization software such as Parallels Desktop or VM Fusion. In any event, Windows generally cannot be run from an external drive.

Booting from a NTFS external HD?
