Using an external hard drive as a main HD.

i haave a 40gb hard drive in my emac, and i was wondering if i could use an external hard drive (120-160gb) as my main drive for music, photos,videos, etc. but still use the internal 40gb for booting up and for applications. And if so, could i use time machine to back up both internal and external drive to one big external drive.
thanks.

tuggers,
Well like Tom says you can use the external drive for storage and still use the internal for booting. Actually like Tom says you could boot from that external if it's FireWire or USB 2.0. The advantage there would be that often things tend to get put on the boot drive if you're doing a lot of video photo. I have the same setup that you're contemplating and my boot drive tends to get filled up so I'm constantly having to housekeep on that drive.
could i use time machine to back up both internal and external drive to one big external drive
Dunno if Time Machine will back up both drives but CCC and SuperDuper certainly will.

  • Will using an external hard drive cause me to have duplicate files on my itunes library?

    I put all my ITUNES MEDIA folder on my external hard drive from my older computer.. I recently bought a new computer and installed Itunes. I synced some of my Itunes purchased songs back on by using my Ipod.. however the songs I ripped from my cds are still not reinstalled in my library.. I will have to use my external hard drive or re rip those.. and there are a lot of them.. since I have already replaced some of the ones I purchased back on using my Ipod will it duplicate them if I use the prefrences method and return them all from my external hard drive? If i delete my files that I have already returned on my new computer before using my external will Itunes remember which are Itunes purchased music and which arent as well>??? also how exactly do you move music from an external? just plug it in and click the prefrences box about syncing files and keeping Itunes library organized?? any other thing to click?

    An iTunes library consists of both the media and the database that knows which files are in the library and hold details of ratings, playcounts, playlist membership and other details not stored in each file's metadata.
    Depending on how you have moved content to your external drive you may find you are only moved the media, but not the database. If you import this media into a new library it will work, but your library will be seen as "new" with respect to any devices that you have and iTunes will want to erase and reload them, losing you current selections, settings and data on the device.
    These are two possible approaches that will normally work to move an existing library to a new computer.
    Method 1
    Backup the library with this User Tip.
    Deauthorize the old computer if you no longer want to access protected content on it.
    Restore the backup to your new computer using the same tool used to back it up.
    Keep your backup up-to-date in future.
    Method 2
    Connect the two computers to the same network. Share your <User's Music> folder from the old computer and copy the entire iTunes library folder into the <User's Music> folder on the new one. Again, deauthorize the old computer if no longer required.
    Both methods should give the new computer a working clone of the library that was on the old one. As far as iTunes is concerned this is still the "home" library for your devices so you shouldn't have any issues with iTunes wanting to erase and reload.
    I'd recommend method 1 since it establishes an ongoing backup for your library.
    If you have an iOS device that syncs with contact & calendar data on your computer you should migrate this information too. If that isn't possible create a dummy entry of each type in your new profile and iTunes should offer to merge the existing data from the device into the computer, otherwise the danger is that it will wipe the information from the device.
    If your media folder has been split out from the main iTunes folder you may need to do some preparatory work to make it easier to move. See make a split library portable. Alternatively you could copy over the iTunes folder and make sure your external drive has the same drive letter on the new system as the old, however moving the library into a portable form will make every subsequent move that much easier.
    Should you be in the unfortunate position where you are no longer able to access your original library, or a backup of it, then see Recover your iTunes library from your iPod or iOS device for advice on how to set up your devices with a new library with the maximum preservation of data.

  • Hello, i am new to the mac and i need to learn how to re image using an external hard drive

    Hello, i am new, like baby fresh new,...lol, to the mac and i need to learn how to re-image using an external hard drive.

    How to replace or upgrade a drive in a laptop
    Step One: Repair the Hard Drive and Permissions
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Step Two: Remove the old drive and install the new drive.  Place the old drive in an external USB enclosure.  You can buy one at OWC who is also a good vendor for drives.
    Step Three: Boot from the external drive.  Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears.  Select the icon for the external drive then click on the downward pointing arrow button.
    Step Four: New Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your new hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID  then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Step Five: Clone the old drive to the new drive
    1. Open Disk Utility from the Utilities folder.
    2. Select the destination volume from the left side list.
    3. Click on the Restore tab in the DU main window.
    4. Check the box labeled Erase destination.
    5. Select the destination volume from the left side list and drag it to the Destination entry field.
    6. Select the source volume from the left side list and drag it to the Source entry field.
    7. Double-check you got it right, then click on the Restore button.
    Destination means the new internal drive. Source means the old external drive.
    Step Six: Open the Startup Disk preferences and select the new internal volume.  Click on the Restart button.  You should boot from the new drive.  Eject the external drive and disconnect it from the computer.

  • I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

    I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

    In the Mac side of things, backups usually come in two flavors: clones or incrementals.
    A bootable clone is a bit-for-bit copy of all essential files in the startup volume. If using the Lions, clones can be made using CarbonCopyCloner or just plain old Disk Utility. These backups represent the safest protection of your info, but take the longest to do. Recovery is an inverse process: you copy the clone back into the internal drive.
    Incremental backups start with a complete backup of the startup volume and only copy whatever changed from the previous run. OS X includes the fully integrated Time Machine backup utility to do this. It is extremely easy to do and takes the least amount of time. Recovery is another matter altogether since you have to start with a freshly installed instance of the OS and have to apply all intervening backups to bring the result to the latest saved version.
    As for where the backup takes place, the recommended media is an external dedicated drive or drives connected via the fastest interface available on your Mac: Thunderbolt, USB3, Firewire, or USB2. Network-based backups, wired or wireless, are attractive but may not offer the same performance and hence take longer. Also important to note that the entire drive need not be completely dedicated to a single backup. The Mac's EFI firmware infrastructure allows for an unlimited number of partitions on a hard drive and each can be used for either type of backups.
    Holler if you need specifics on how to do each. This was just an executive summary.

  • Restoring using an external hard drive help

    Ok so.. ive recnelty received my mac back from apple, after javing the hd replaced. To prevent the loss of all of my stuff i bought an external hd and used this as my time machine backup, so now its all on my external hard drive. The problem ive got is that ive got no idea how to restore my mac using the extermal hard drive so its like it was before it was sent off. ive been told one option is to launch my mac in recovery mode and choose to restore using. my external hard drive there. however i cant access recovery mode because i have a wireless keyboard, and the only wired keyboard i have is a windows one. also, to make matters worse, i cant use any discs because my optical drive is broken, so until i receive my extermal one, discs are also out. of the option.
    any other ways to do it?
    thanks!

    Try this, your going to be using a program called Migration Assistant to restore data from a different computer's Time Machine. Your computer is a different computer now because of the new Hard Drive, so instead of entirely recovering the Operating System, this will save time and data by allowing you to choose individually what you want to restore and what you don't want to.
    Do not use Migration Assistant, instead you will use Setup Assistant (which starts automatically when you first start your Mac) if you already started you Mac and added a user then you will have to use MA, but you will need to remove a user afterwards.

  • Can some please provide instructions on how to import an iPhoto library from an old Mac to a new Mac without getting a bunch of duplicates?  I tried transferring my pictures using an external hard drive and then copying it to the Pictures folder on my Mac

    Can someone please provide instructions on how to import an iPhoto library from an old Mac to a new Mac without getting a bunch of duplicates?  I tried transferring my pictures using an external hard drive and then copying it to the Pictures folder on my new Mac.  I ended up getting a bunch of duplicates. My old Mac has an older version of iPhoto while the new Mac has iPhoto '11.  Is that the cause of the problem?  Please advise.  Thanks.

    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.

  • How do I transfer my data to my new macbook pro using an external hard drive?

    I've already set up my new MacBook Pro is my issue. It asked me if I'd like to "Migrate" my stuff or use an external hard drive etc but at the time I didn't transfer my data from my old MacBook yet. I was going to manually do it later as I had to wait for my External hard drive to back my old Mac up. Now it's that time and I have no idea how to do it. I believe I've researched best of my ability.
    I feel like I'm asking a pretty dumb question. If I were to just drag all my programs out like my Adobe Suite on to my new macbook pro would that work? I feel like that's just too easy and incorrect. Please and thank you.

    The Adobe suite can be downloaded free, you dont have to copy it at all, under standard CS6 Adobe rules, if you own the suite, you get 2 computers "activated at any one time"  Make sure, if youre not using the older computer, you deactivate the software under the HELP menu in Adobe.
    format the new drive in disk utility ......APPLICATIONS.....UTILITIES.....DISK UTILITIES.......select the external drive and format (if its new and empty!!!) under the ERASE button with Mac OSX extended journaled
    copy all your important stuff from older computer , pics, files, documents, personal anything.
    most of you apps, i ASSUME you bought in the (other than Adobe software, or Office suite, etc etc,..... obviously) in the MAC APP store, so you can reload them on the new computer without copying them , makes things very easy......just open APP STORE, and download what you already bought.
    really the only important things , is copy all important work files, documents, pictures, personal ABC...XYZ......  obviously.
    the migration is about emails, contacts, etc etc etc, also data, just because you passed it by at the time doesnt mean you still cant do it,    go to the SEARCH at menu at top and type in MIGRATION ASSISTANT  to do it again , since you passed it by at first .
    the only thing you NEED / SHOULD copy is all your personal stuff........Applications need to be reinstall from either ONLINE download,.......or from the MAC APP STORE,........  you cant just copy the apps over (in most cases) and toss them onto the new computer
    Nahh, there are no dumb questions, just dumb mistakes because you DIDNT ask any questions, and we all make those here and there.

  • Can I use one external hard drive for 3 of my Macs?

    I have a 2007 white MacBook, a 2011 MacBook Pro, and a 2013 MacBook Air.
    I want to be able to transfer all of my precious family photos off of my MacBook and Macbook Pro onto an external hard drive and then wipe those computers clean, and then I want to be able to backup and wipe clean my Macbook Air so that I can update it to Mavericks.
    Can I use one external hard drive to do this for three of my Macs? Will it be compatible with all of them? And will I still be able to use the hard drive with my Air once it is updated to Mavericks?
    Which hard drive do you recommend?

    1. Yes. Note that anything you want to keep should be on at least two drives in case one of them fails.
    2. Yes.
    3. Yes.

  • How can I use my external hard drive for my iphoto instead of my mac book pro memory?

    i don't know if this question has been asked before: how can I use my external hard drive for my iphoto instead of my mac book pro memory? just like itunes all my song are save on my external hard drive. make sense?

    Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
    And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
    And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

    heidie22, dj_paige has a very good point there. I would not through away the NEF files; I would archive them to a external drive.
    By the way, I am assuming that converting RAW files to DNG is a decision you have made and not an accident.

  • How do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full

    how do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full.. HELP!

    When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as  Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
    See this support article for some simple ways to free up storage space.
