Can I put my startup/home folder on an external drive?

I would like to stripe my four internal drives for a high-performance RAID 0 for video editing.
Is there ANY reason that it would be unwise to put my applications/library/system/users folders on an external firewire drive? (Of course I will continue to do regular backups of these folders, regardless of where they live.)
Any performance issues, startup issues, etc, that I should be aware of?

External drives are slower than internal drives but otherwise there's no reason you could not do it. I would not recommend it. I would leave one internal drive as your startup drive and stripe the other three. This would be the faster and more reliable alternative in my opinion.
Consider putting in a goodly amount of RAM which will also help with video work and limit the amount of disk usage during editing of large files.

  • How do I move my Home folder to an external drive?

    I am leaving for 3 months.  I want to copy the entire Home folder on my iMac to an external drive so I can take it with me.  I want to clean up the files/folders, sort and delete thousands of iPhoto pictures, organize hundreds of genealogy documents, etc., using my MBPr.  When I return home, I want to replace the old Home folder with the cleaned up one.  I thought I could simply drag and drop the Home folder to the external drive (2 TB) but twice now I get these two dialogue boxes mid-way.  After the second, the copy window disappears and copying stops.  A shadow of the Home folder is on the external drive, but nothing else.  Can this be done?  How?  Thanks!

    1, Yes. Making a partition for the clone is what you want to do if you want a bootable clone.
    2, If you want a bootable clone, you do not want to create disk image.
    3, Dragging and dropping will not get all of the files the was cloning software will. Using drag & drop uses more superficial commands then the cloning software uses. So that is is not able to get everything.
    The next two link are a couple of site that explain how to set up SD to clone a disk.

  • Is it possible to install my home folder on an external drive?

    I need to hand my MacBook in for repair, but I don't want any of my documents on it when it goes in to the repair shop. I have full Time Machine back-ups of the entire laptop, but is there any way I can install my home folder on an external drive so that while my laptop is being repaired I can continue working as usual with my external hard drive plugged in to another (older, smaller hard drive) laptop?

    Get an empty external drive properly formatted. Get Carbon Copy Cloner 4.0 and use it to backup your Home folder to this external drive. Create a new admin user account and turn off auto login if it is enabled. Reboot the computer and sign into the new user account. Delete your user account.

  • How to Encrypt Home Folder Located on External Drive

    I have an iMac 5K with a 512GB internal SSD.  I decided to relocate my users' home folders to an external HDD due to their size (won't all fit on the SSD).
    That part is working fine.  However, it has now dawned on me that I would like to encrypt those home folders in case that external HDD is stolen.  The problem, of course, is that by encrypting that external HDD, those users won't be able to login, since you can't login if your home folder is not immediately available.
    Only solution that I read about is to have another user (with a home folder on the SSD) login first after startup and decrypt the HDD.  The would then allow the other users to login successfully.
    Is that the solution I should go with here?  Or is there some other approach that will work better?  Or should I move my home folders back to the SSD and just keep the large stuff on the external HDD?

    If your pictures, music, movies are not sensitive, you could relocate those to the external drive.

  • I created a new home folder on an external but didn't move my old files over. Now I can't see the old hard drive in my mac mini. How can I locate that drive?

    I wanted to move my home folder to an external drive. I created a new home folder and in advanced options I moved it over. I didn't however move my files over first, my bad. Now I can't see the hard drive on my mac mini. Is it possible to reverse it or get access to the old home folder and is it possible to still use the mac mini's internal hard drive for storage? How do I find my shared folder, it was on the internal drive. I'm new to macs as you might have guessed at this debockle. Can anyone help?

    I'm using Mavricks. I wanted to move my home directory to an external and went into sys prop/users/advanced options and moved the folder ok. Being a noobie on Macs I didn't copy my data and such. So my settings were all new. Basicly now I don't see the internal drive on my mini. There is a lot of strage I'm not able to access. The internal drive doesn't show up. How can I put a folder back onto it so it shows up?

  • How to relocate Home folder to second internal drive

    What is the process to migrate my Home Folder from the boot drive (256Gb SSD) to a new internal drive (960Gb SSD)? Can this be accomplished in finder or should one use the Terminal window?

    Interesting, I'm having the same issue on my MacBook Pro that has both an SSD (for the OS and Apps) and a Hard Disk in place of the Superdrive. This config worked just fine with Mountain Lion; since upgrading to Mavericks this morning, I am unable to log into my personal account that has its home folder on the hard disk.
    Unfortunately, it also seems to be an issue with the library folder, as I've been able to solve this issue with symlinks just fine with the exception of Library: the system keeps asking me to key in my password because the Library folder "needs to be repaired".
    I can't move my Library folder to the SSD, as it is way too big (for whatever reason) - the SSD is only 96 Gig.
    What is so different here is that the hard disk in the system is encrypted - I think this is the problem. I don't understand why, though, because under ML, I just logged in as admin after every reboot, which mounted the encrypted disk and then logged out / logged back in with my user account - it worked just fine.
    Something seems to have changed with Mavericks regarding making available the encrypted HD...
    Oddly enough, on my Mac Mini at home, which also has the SSD/HD pair, the moved home folder works fine - of course, here the HD isn't encrypted...
    I hope someone has a fix for this, otherwise I'll have to go back to ML!

  • Storing Home Folder on a separate drive OK?

    Can I store my Home Folder on a separate drive? I am thinking about getting a Raptor drive for my boot drive. But the size of the HD won't fit all my music, docs, movies and pics.
    If this is OK, and it does not screw with the OS, how do I do it?
    Copy to a new drive, but how do I direct the OS to that Home Folder and apps to save info there?

    Hi
    You can - you just have to make sure that you always have the external drive connected all the time, otherwise the system will create a blank home folder. It's probably not a great idea to do this for a portable computer. Instead, I'd recommend perhaps moving just your music, pictures and/or movies.

  • After moving a folder to an external drive i can still see the images even with the external drive off

    I have moved a folder with a lot of subfolders onto an external drive but when I disconnect the external drive I can still view them in Lightroom. I thought this took them off my Mac Book Drive.

    The previews that LR makes for itself are small and their size can be set in Preferences. The default is around 1600 pixels wide and it should be set to the size closest to your monitor resolution.
    Another feature that might interest you is the ability to make Smart Previews, either at import or later. The SP is a 2560 pixels wide DNG, whereas the normal preview is a jpg, and as such can act as a surrogate for the Raw file and can be edited in place of it when the external drive is offline. When the drive is reconnected, the edits are associated with the original.

  • I have a new western digital 1TB ultra. how do i format it? i can't create a new folder inside the external drive.

    I have a new WD My Passport Ultra external drive. Once connected to the Macbook Pro retina, I can't create a new folder in the external drive. What do I do to solve the problem?

    You should be able to format it for use with your computer using Disk Utility in the Utilities folder:

  • HT201250 Hi, I had updated folder on my hard drive wich was wrongly replaced with a folder from my external drive. I m not using time machine. How can i recover that updated folder? (it was done on 3-5-12)

    Hi, I had updated folder on my hard drive wich was wrongly replaced with a folder from my external drive. I m not using time machine. How can i recover that updated folder? (it was done on 3-5-12)

    If the folder was replaced, it was written over.
    Nothing short of forensic data recovery (probably involving taking the drive apart to scan the discs seperately) is going to recover anything (if indeed even that will).

  • Can I dedicate specific folder in my external drive for Time Machine to download to

  • How to move Startup Disk clone from one external drive to another?

    I thought this would be a question easily answered on the WWW and easily found via search engines, but so far no luck, hence this question.
    Prior to upgrading from Lion to Mountain Lion I followed some very good instructions from Tom Nelson on ask.com (http://macs.about.com/od/backupsarchives/ss/diskbackup.htm) related to using Disk Utility to clone my internal Macintosh HD drive to an external hard drive, making it a bootable drive.  I cloned to a very nice LaCie external FW drive that had far more room than that needed for the clone.  This drive booted just fine as a startup disk, so mission accomplished:   I have now a bootable clone of my Lion system prior to upgrading to Mountain Lion. 
    The upgrade to Mountain Lion went well, and now, before I put any additional apps or much additional data on the original internal  Macintosh HD drive, I want to use Disk Utility again to clone the drive so I'll have a snapshot of the system right after the upgrade to Mountain Lion.
    Questions: 
    Is there any way to use the same LaCie drive that now holds the Lion startup disk clone to hold the yet-to-be-done Mountain Lion startup disk clone?  
    If not, how can I move the Lion startup disk clone from the oversized LaCie external drive to a drive more the size of the Lion clone (approx 140G)?   The LaCie drive is far too roomy and nice to have sitting gathering dust for only 140G to be used in an emergency restore. 
    Thanks in advance for your advice.

    Good info Csound1, and thanks. 
    So my final question (I think):  How does one move/copy a startup disk clone from one external drive to another, and still have it bootable on the new external drive?   I'm still considering freeing this LaCie drive up for more dynamic storage and getting another drive for the bootable startup disk clones IF I can move this Lion startup disk clone to a new external drive. 
    I guess the summary question is:   how does one clone a startup disk clone?  As I think about this, and recall the Disk Utility screens, couldn't I simply select the Lion clone on the LaCie FW external drive and do the same operation I did with the original internal Lion drive?  Basically the same steps as before but this time the source is the LaCie FW external and the destination is a new external drive? 
    Thanks again; wonderful forum here with very smart people.  

  • I have moved my Itunes media folder to an external drive and Itunes does not find the items in the folder

    Running Win7. I moved my entire Itunes library to an external drive to free up space on my laptop. Itunes recognized the change and all was well. That worked fine and I have synced several times from the laptop with the library on the external drive. Now the laptop is in the shop (sigh, not Itunes related a dead network card). I connected the external drive to my desktop, made sure my software was up to date. opened ITunes went to edit/preferences/advanced. Went to change Itunes media folder location and navigated to the proper folder on my external drive and clicked OK. None of the music, videos, etc, that are in that folder show up in iTunes on the desktop. Restarted ITunes, no help, reboot computer, no help. Have I done something wrong or left out a step. I could copy all the media onto the desktop individually and build new playlists but that seems like something that should not be needed? One of the reasons I moved my Itunes media folder to the external drive was so I could use the laptop for iTunes while travel and the desktop for iTunes while at home. Do I have to copy the entire folder to my desktop and take up space there? That would be counterproductive to using the external drive. I searched and saw a hint to hold down shift while starting ITunes but that did not change anything. Any help would be most appreciated!
    Jim in WV

    Thank you for your prompt response - I did as you said and did a drag and drop into the iTunes window - it imported and got my album art from the net. When I started Itunes with the shift key down I was prompted to choose a library but since I copied over the media folder and not the library folder I was unable to select that so I guess I will have to create a new library and add in all the music, videos, etc. unless I wait for my laptop and export the library or at least that seems to be the case? In short, all my data (iTunes media folder) is on my external drive and can be added to the blank iTunes screen but I can not choose a library folder. Is there anyway around completely making all those playlists again? I am not sure my laptop will survive the shop with data intact and really hate to start over on those.
    In an unrelated question - I collect old TV shows from the 1950's. Can I make playlists within the home video folder somehow?  In other words like one for Quiz shows, one for comedies, one for police and detective shows, etc. while I am remaking all my playlists for my music if I end up having to go that route?
    Once again thank you for helping me out. I am not too Itunes savvy and really appreciate you taking the time to answer.
