Will a Thunderbolt external hard drive be able to boot the Thunderbolt MBP?
Are there Thunderbolt external hard drives available and will they be able to boot the Thunderbolt MBP?
Thanks.

MMMM Why would you want to boot from a slow external drive instead of the on board SSD (Retina MBP) is the question.
My Tbolt externals WDs 8TB Duos only give roughly 1/4 (25% performance) compared to internal SSD, Externals are normally for backup operations and too slow for the amount of read/writes required for a BIg OS such as OS10.8, Max write speeds are determined by the donor disk, even when in 2x2 stripe in Raid 0 only clock about 500GB per hour ( any one getting over this please send screen shots for verifiaction and number of disks used in the array), bursts in smaller file are quicker.
Power PC if I remember correctly is not x86 compliant and running Snow leopard on a MBP retina is like running MS 3.11 on a gamers platform.
Various forums say that OS 10.8 WILL NOT boot from Tbolt running any Raid (0 1 5 6 or 10)
There is a backward and forward compatbitly issue with which way you are firing the data, put simply a tbolt drive with Firewire to Tbolt adapter cable is only as quick as the firewire and may not justify the cost. Also 2 machines = 2 boot partions to accomodate the different hardware inside each case.
You may be better of installing Paralells (Apple Store $100 including USB 3.0 Cable which is backward compat with USB 2.0) and running VM (Virtual Machines) using OS 10.8 on the Retina and using the older machines as displays. It boots windows linux ubuntu and more into VM without rebooting the machine and works seamlessly in the named OS's
Hope this helps

Thunderbolt external hard drives unexpectedly eject
Aloha, This is my first post to the community and I would greatly appreciate any help.
I run two thunderbolt external hard drives: 3 TB Seagate Backup Plus and a 2 TB LaCie lessee drive.
For several months, both drives will eject for no apparent reason. Recently, the 3 TB Seagate drive will only periodically mount. I can feel the drive spin and a light will go on, but it does not mount. This is a partitioned drive and on one partitions is a very large Aperture library, and being able to have access to these assets is becoming a concern.
Additionally, I have been able to get the Seagate drive to boot, but was only able to see one of its partitions. When I ran Disk Utility, the drive unexpectedly ejected.
Steps taken to address the issue
I have done numerous shutdowns to include unplugging the power cord from the computer, depressing the start button for 15 seconds, plugging in the power cord and waiting 30 seconds before powering up the machine, then plugging in the power cord to the hard drive, and then the thunderbolt cord to the computer, and have used two different thunderbolt cords, in addition to resetting system preferences and cleaning cachet's.
Computer:
27 inch iMac (three years old)
OS 10.9.5
3.4 GHz, Intel Core i7
16 GB 1333 MHz DDR 3
External Hard Drive
Vendor Name: Seagate
Device Name: GoFlex Desk Adapter Thunderbolt
Route String: 3
Firmware Version: 26.0
Port (Upstream):
Status: Device connected
Link Status: 0x2
Port Micro Firmware Version: 0.2.5
Cable Firmware Version: 0.1.22
Port:
Status: No device connected
Link Status: 0x7
Port Micro Firmware Version: 0.2.5
I am no expert: essentially I know enough to get into trouble. Might the issue be the iMac thunderbolt connection, given both drives sporadically eject? or might it be the thunderbolt connector that the drive sits in, given that I can occasionally get the drive to mount?
Any and all thoughts are greatly appreciated!
Mahalo nui loa (Thank you very much)Aloha,
It was a long week. Here is an update.
Had the opportunity to go to the Apple Store yesterday and purchase new thunderbolt cables, and hooked everything up this morning.
I disconnected the Seagate drive from the sled, and brushed the contacts.
The Seagate hard drive did not boot on my iMac and Disk Utility could not see it. That said, when booted to my wife's iMac, Disk Utility could see the drive, but I could not verify or repair it. The data from my wife's iMac is attached.
Also, I tried to run Data Rescue 4. It would not see the drive. I do have Disk Warrior, if that is a reasonable option to try.
Additionally, the LaCie (now connected to my iMac with a new thunderbolt cable) has not yet been ejected. The computer has gone to sleep several times and I have awakened it.
I very much appreciate your thoughts and time, And I look forward to your thoughts, To include any experience in getting the data off of the Seagate. It contains seven years worth of photographs, which I would hate to lose. I also got the message about redundant backups. There may be some of the backup in Crash Plan.

How do I have itunes use/detect my external hard drive and place music on the external drive from the itunes store? There are no music files on my pc yet. I will like to do this after installing itunes 11 on my pc for the first time. I am using windows 7. HP computer intel Dual Core. Thanks for any help!
Hey idw3,
Welcome to Apple Support Communities, and thanks for the question. Follow the instructions on this article to move your iTunes Media folder to an external hard drive:

I am trying to backup my Itunes onto my external hard drive. I am at the step where I on Itunes, click on File ->Library ->Organize library. I am suppose to check mark both boxes there, the first being "Consolidate Files" & the second being "Reorganize files in the folder 'Itunes Media'. I am able to checkmark the first box but It won't allow me to check mark the second box, why? How can i fix this? Please help!
Well you must have made a mistake somewhere. The last instruction of step four reads:
When you've found your iTunes library folder, drag that folder to your external hard drive. This will begin the iTunes backup. The amount of time the backup will take depends on the size of your library. When the transfer is done, your backup is complete and your external hard drive can be disconnected.
Normally dragging content from to a new location on a different drive will result in a copy action which is what you were supposed to do. At a guess you somehow managed to move the iTunes folder. Then when you started iTunes it created a new blank library for you assuming it had just been installed rather that raising a warning.
Close iTunes. Rename the iTunes folder on the internal drive as iTunes (Empty) then copy the iTunes folder from the external back into the User's Music folder. Start iTunes. All should be well.
When you've made sure it all works please read my User Tip and use that method to backup in future. Since you already have a folder with the backup in place you can skip the "Make New" operation in the fourth step and simply choose the external folder.

Hi,
I have been rebuilding our iTunes library on a external hard drive, no problems to start with. The pc crashed the other day and I lost some of the files.
I can see the music files on the external hard drive, but I haven't been able to get iTunes to pick them up as being the library despite following the instructions to map the drive under 'preferences' in iTunes. I have added new songs, these are being saved in the folder on the external hard drive and are showing in the library pane on iTunes, any suggestions how I can get the other files to show in the library? Would be very grateful for any help! Thank you.The fix for the exclamation marks is: Adobe Lightroom - Find moved or missing files and folders
The proper way to use backups is to restore the photos to their original location, but you probably don't want to do that as you said your old hard disk was almost full. Thus, the solution given above will solve the problem. -
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?
Because if the drive is working physically, then there is a host of fixes

I have a new Mac Pro computer and have migrated my files from my older computer to the new computer. In trying to open a Lightroom catalog on an external hard drive I keep on getting the message "lightroom cannot use the catalog named " " because it is not writable and cannot be opened. I have fixed all the "permissions" and yet it will still not open. How do I fix this?
Hello Forum Members,
I figured it out. You have to select the actual logo of the Lightroom catalog and then click on "get info" and allow what ever your new user name to "read and write". That worked!

Is there a possibility to recover erased files from an external hard drive that was reformatted by the Time Machine?
Basics of File Recovery
Files in Trash
If you simply put files in the Trash you can restore them by opening the Trash (left-click on the Trash icon) and drag the files from the Trash to your Desktop or other desired location. OS X also provides a short-cut to undo the last item moved to the Trash -press COMMAND-Z.
If you empty the Trash the files are gone. If a program does an immediate delete rather than moving files to the Trash, then the files are gone. Recovery is possible but you must not allow any additional writes to the hard drive - shut it down. When files are deleted only the directory entries, not the files themselves, is modified. The space occupied by the files has been returned to the system as available for storage, but the files are still on the drive. Writing to the drive will then eventually overwrite the space once occupied by the deleted files in which case the files are lost permanently. Also if you save a file over an existing file of the same name, then the old file is overwritten and cannot be recovered.
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.

I have an imac 2009 the disk drive is damaged and I have lost the passwords I need to reset passwords I tried booting with a macosx disk from an external hard drive but did not read the drive how else can I reset password ?
I have a 2012 mac book pro can I use that to connect with firewire and load osx that way? and how woudl I do that?
Thanks so much!To what password are you referring? Do you mean your user account's admin password? Or do you mean the master password for File Vault or do you mean a Firmware Password?
For an admin password:
Forgot Your Account Password
For Snow Leopard and earlier
Mac OS X 10.6- If you forget your administrator password
For Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
When the menubar appears select Terminal from the Utilities menu.
Enter resetpassword at the prompt and press RETURN. Follow
instructions in the dialog window that will appear.
Or see Reset a Mac OS X 10.7 Lion Password and
OS X Lion- Apple ID can be used to reset your user account password.
If you cannot do the above then try this:
1. Boot to Safe Mode by restarting and after the chime press and hold down the COMMAND-S keys until a black screen with white type appears.
2. At the prompt, type the following commands pressing return after each command line:
/sbin/fsck -yf
If you do not receive a "Filesystem OK" message then repeat this command until
you do. If after seven tries you still do not receive a "Filesystem OK" message,
then the system is corrupted and needs to be reinstalled.
mount -uw /
cd /private/var/db/netinfo
mv local.nidb local.old
rm ../.AppleSetupDone
shutdown -r now
The second-to-last command above will cause OS X to think that the operating system is newly installed, and when the new owner starts up the computer it will send him/her to the startup wizard where he/she can start a new user without reinstalling.
This last method does not actually change a password. It simply removes the user accounts and lets you create an initial admin account as if the computer were new out of the box.
How to reset the OS X password without a startup CD:
Reboot into Single-user Mode. Enter the following and press RETURN after each command line
1. Type fsck -fy
2. Type mount -uw /
3. Type passwd <username>
I have never tried this method myself. -
I get the following error when formatting a external hard drive.
Partition failed with the error:

I have a Macbook pro 13" A1278. I purchased it around december 2010. I have a HHD 3.5" drive desktop select II 1.5TB. I purchased it around Febuary/March 2011 to use with my Macbook pro. I formatted it and moved all my files to there, I got it so my macbook's hard drive wouldn't brake and I lose everything on my macbook.
Is there any fixes?First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes." -
And how do I turn off FACES?
I copied the iPhoto library to an external hard drive, then imported it to the new iPhoto. It turned my 2000 photos into 12,000!!
According to you youo did not do what I instructed - you said you imported the old library into th enew library which can easily take a 2000 photo library and turn it into 12,000 including two ro three versions of each photo pus all the face thumbnails
The correct procedure has NO importing involved
drag the iPhoto library intact as a single entity from the old Mac to the pictures folder of the new Mac - launch iPhoto on the new mac
That is it

If i have Time Machine backed up on an external hard drive, do i just plug the drive into another macbook pro and all my stuff is in the new computer? Also, does it matter if the new computer is running Lion when the backed up info came from Snow Leopard 10.6.8?
No and Yes
Don't use TM for this purpose, clone your drive to an external, plug the external into another MBP and reboot from it. Please note that booting a machine that came with Lion may not be possible from a drive with Snow Leopard. -
i tried transferring my iphoto library from my old macbook onto my new macbook pro (via external hard drive), but when i open the new iphoto, it seems to have transferred ALL images ever used on my old macbook. so i tried to just delete all those images so i could try a different approach to transferring, but the new iphoto won't let me do anything and every time i try to delete anything it crashes (since the image amount is so high). please help!!
MacBook Pro, OS X Mountain Lion (10.8.2), iphoto '11, version 9.4.2To move an iPhoto Library to a new machine:
Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
But however you do choose to link the two machines...
Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
Then launch iPhoto. That's it.
This moves photos, events, albums, books, keywords, slideshows and everything else. -

My external hard drive wont show up in the "Save to:" menu when I try to import videos
My old external broke so I found my old one and plugged it in and went to import some videos on imove from an sd card but my external hard drive wont show up on the "save to:" drop down menu. I've been on utility disk to try and repair disk permission but I can't because the button isn't lit up. I can only click on verify disk or repair disk. I tried both of these but it still wont come on the drop down menu. It is showing up on the left in the event library but it has a little yellow triangle with a black exclamation mark in it.
Hope that all makes sense!
