Partition a external HD

I bought a LaCie 500 Gb external firewire/usb hard drive. Have archived some files by simple drag and drop process.
Would however like to partition a volumn on the new external hd and clone a bunch of applications (have super duper).
How do I partition the external hd?

wmowbray:
Here are step-by-step directions, a bit more detailed than in the Knowledge Base article:
Formatting, Partitioning Erasing an External HDD
• Connect external HDD to computer
• Turn on external HDD
• Start up computer and log in
• Go to Applications > Utilities > Disk Utility and launch DU.
• Select your HDD (manufacturer ID) in left side bar.
• Select Partition tab in main panel.
• Click on Options button
• Select Apple Partition Map (PPC Macs) or GUID Partition Table (Intel-based Macs)
• Click OK
• Select number of partitions in pull-down menu above Volume diagram.
For more partitions than one, after you have selected the number of partitions adjust the size of the partition by selecting the top partition and typing in the size; then move down if more adjustments need to be made.
(See Dr. Smoke’s FAQ Backup and Recovery for tips on partitioning external HDD)
• Type in name in Name field
• Select Volume Format as Mac OS Extended (Journaled)
• Click Partition button at bottom of panel.
• Select Erase tab
• Select the sub-volume (indented) under Manufacturer ID
• Check to be sure your Volume Name and Volume Format are correct.
• Click Erase button
• Repeat above procedure to erase each partition
• Quit Disk Utility.
Good luck.

  • HT201250 Do I need to partition my external hard drive if I'm using Time Machine and other storage?

    I never used Time Machine before.  I was storing select files on my external hard drive as well as using my libraries (IPhoto, ITune, IMovies) directly off of the external hard drive.  That hard drive is giving me problems, so I bought a new one.  I want to set up Time Machine on this one, but I also want to keep my active libraries on it.  Do I need to partition the external hard drive?

    You can partition the new drive, just don't make one of the partitons a TimeMachine drive, save a TM for a entire drive with more space than the boot drive as it saves "states" thus requires more room than most people expect.
    I highly advise one drive to one drive for backups, and not placing too many backup eggs in one vulnerable hardware basket basically.
    Drives are cheap, data is not. Hardware can fail just as often as software, so you need a multiple backup and storage stragedy to protect even against theft and fire.

    Why not? does the partition tab not exist?

    Whoa! Slow donw. TRhere's a lot here. I would suggest you buy a good book on computers in general or macs in particular, one is "OSX the missing manual".
    What does it mean to "partition" the external hard drive?
    It means you take one large drive and make it into more than one volume. This means that it might show up as 2,3 or 4 inde[pendenmt drives. Each one could have, for example, a different operating system on it. Its  a good thing to do if you want to use a drive for several purposes
    Is it something I want to do?
    beats me, you didnt way what you're trying to accomplish. Sorta like sking "should i turn left?"  Depends on where you want to go.
    How do I save files from another hard drive to the new one?
    See advice n book above. Copy them in finder. Copy them in unix. Use a backup or sync utility. No different from Windows in that respect.
    I have to reformat the old one as it was not set up correctly.  The drive I have is Seagate but not specifically for MAC, so I have to format it.. never have done this before. Don't know the jargon.
    Hook it up. Run disk utility. Partition 1 or more partions. GUID map.  Format each partition Mac OS extended, Journaled.  for more, read book, above.  Seriously - we could give you more tips, but you really should learn enough to be comnfident.

    I have no idea what you are asking.

    What kind of memory and why?  RTAM? Hard drive space? Explain. By the time you are done explaining, i suspect you will have ansered your own question.
    Good luck,

    I have an IMAC and I'm running OSX 10.9.2.  I'd like to store my Aperture /IMovie Libraries on an external hard drive.  In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives.  Is this possible? Can I set up a RAID 5 format for redundancy?

    I'd like to store my Aperture /IMovie Libraries on an external hard drive.
    That is fine and recommended.. use the fastest disk you can afford.. ie Thunderbolt>USB3>FW800>USB2.
    In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives.
    Let me be clear.. you want to partition the one disk.. use it for TM and move your files to the external disk.. and then backup to the same disk.. You can do it.. but that is not a backup.. that is an experiment in how long you can get away with running files and backups on the same disk before you lose everything.. like Russian Roulette.. pull the trigger enough times and laws of probability will do you in.
    You must have backups on a different disk .. otherwise it is pointless.
    Can I set up a RAID 5 format for redundancy?
    No.. you can buy special USB and Thunderbolt external drives that support RAID..
    BUT that is still not a backup.. let me show why.. you make a silly move and corrupt your file in aperture.. it is not that rare.
    Raid will corrupt all copies of the files.. it is replicated across all disks.
    Delete a photo it is deleted across all disks.. you have no recovery.
    Alway, always consider RAID system one disk.. backup onto another disk.. and if the photos or movies are at all important to you.. ie your family .. make another copy and store in a relatives house.. There is no such thing as too much redundancy.

  • How Do I partition an external hard drive using disk utility?

    I have a 500 GB external hard drive that I want to set up so that half the space is for Time Machine backup and the other half as a simple flash drive that will be compatible with all types of computer operating systems?

    A terrible idea. Never use a backup drive for anything but a backup drive. Get another drive for experimenting.
    You can partition an external drive no differently than an internal drive.
    Drive Preparation
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions desired from the drop down. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) 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 Security 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.
    Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

  • Problem creating Mtn Lion Recovery partition on external drive.

    USB external.  Newly erased, three partitions: one 2GB for Recovery HD, other two backups of my old SL machine and new ML machine (Mini). Those work and their respective machines fine.  Drive seems OK.
        Used Recovery Disk Asst v. 1.0 to create Recovery HD on the small partition while booted into 10.8.2 (the brand new Mini).  Factory installed Mtn Lion Recovery HD exists on internal drive and it works— when starting with command-R or command-shift-R, not with Option key.     Install of Recovery HD to external seemed to go fine and doing a "diskutil list" in Terminal showed both the internal and external Recovery HD's, properly named as such.   However, when restarted with Option down the recovery partition showed up named the same as my internal— at that point "Macintosh HD" but later when I changed the internal's name, reinstalled the Recovery HD, and restarted with Option key the recovery partition now was named the same as new internal drive name.   Both times choosing the recovery partition resulted in booting into internal drive.   
    Was wondering if anyone had a similar problem— and found solution/reason.   Apple Tech Support particularly not helpful/knowledgeable on this subject. 

    Hi Baltwo
       Really appreciate the help.   Many thanks.     Finally seems to be working.     Not sure exactly what worked but in case you're interested I'll give you a, hopefully, short summary:
    Using DU (after copy/paste of the command you wrote above into Terminal) I cloned the working internal drives RDH to the partition for it on the ext.   Failed— still seemed to work as almost an alias pointing at the boot volume on the internal.
    So, erased the external again; didn't partition, did a reinstall of ML from DU while booted into RDH of internal.  Then started from that new ML partition on external and let Setup Asst migrate everything over from the internal to keep Users/Permissions from being a problem.
        When that finished I tried to restart w option key.   Got a recovery HD that was called exactly that but, again, booted into internal boot drive.   Booted into internals RHD just to make sure it was OK and it was.
       For whatever reason again restarted w option key.   This time I got four choices:  the boot volume of internal and external, an ext volume called Recovery HD (the trickster), and another volume called Recovery 10.8.3.   Something new— and, as Bill Murray said in Ground Hog Day, "anything new is good."   So I tried booting into that new RHD 10.8.3.  (Note, I'm still running 10.8.2 on boot volumes.)
      And that worked— booted into Recovery HD but no way that I could figure to see for sure that it was the Recovery HD on ext vs. on internal.   I think I need to activate the Debug menu on the RHD DU so I can choose the 10.8.3 recovery and see if I have the option of Repairing the disk or it's greyed out.  If greyed, then proves I'm booted into it.   Might be a more elegant way to see that but it's the one I know.    Still, I assume I was in the RHD on the external.
      Then made a second partition for the old mac's backup and that initially resulted in the boot volume of the internal backup not be mountable but after a restart or two testing the two RHD's, the mini decided to see all the volumes and things are, for the moment, copacetic.  
      Hope that wasn't too long and boring.    From my experience and reading on the 'net, my general sense is that there are a bunch of variables that all have to be right for this process to work.  Probably less is more and just installing ML on a disk by itself will be the most reliable method, if most wasteful of data storage. 
    Regardless, couldn't have done it without you, baltwo.   I don't use this forum enough to know what the etiquette and protocols are but I marked all of your posts as useful, which they were, and, finally, as solving my issue, which they did. 
    Thanks again

  • Partitioning an external hard drive for Mac and PC

    I want to partition an external hard drive (3TB) into 3 even partitions. I want to use one for PC storage, one for Mac storage and the last for Mac backup. Is this possible and how do I do it?

    Drive Partition and Format
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply 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 Security 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.
    7. Re-partition the drive to create the three partitions. The one you wish to use on a PC you should format MSDOS (FAT).
    When you connect the drive to your PC it should have no problem reading the partition set up for a PC. Now while on the PC you may wish to consider reformatting that partition using ExFAT (if supported on your PC.) This format is more compatible with both OS X and NTSF supporting long file names and other FAT filesystem irregularities.

  • Basic Question:  How to partition an external drive and then set up TM?

    Hi. I am going to be using an external hard drive (Western Digital - 640GB) on my MacBook for the first time and I think that I'd like to partition it so that part of it is for Time Machine and part of it can be used to just manually drag and drop my files (like any other USB external drive).
    1. How to I partition the external drive for Mac?
    2. If I insert my drive (not yet partitioned) in my MacBook for the first time and the MacBook automatically asks me if I want to use it for Time Machine, I'm assuming that I need to say "no" so that I can first partition it, right? If yes, then after partitioning it how do I set up the one partition for Time Machine?
    3. If I have 640 GB external hard drive space and my MacBook has about 100GB of space, how much of the 640 should I allocate for Time Machine?
    Thanks! Happy New Year!

    select the whole drive (the model, not the name) in disk utility and click on the partition tab. set the number of partitions. set the partition scheme to GUID in options. set the format to mac os extended journaled. hit apply.

    in system preferences->Time machine.
    also see TM 101 for basic usage instructions.

    3. If I have 640 GB external hard drive space and my MacBook has about 100GB of space, how much of the 640 should I allocate for Time Machine?
    it depends on your computing habits but it's generally recommended to have TM drive to be at least 2-3 times bigger than the total amount of data you are backing up.
    Thanks! Happy New Year!

  • Can I partition my external HD for both Time Machine and for basic disk use

    I wanted to know if through Disk Utility I can partition my external HD so that I have about 400 gigs for TM and 100 gigs just for storage? Thank You in advance

    Yes, you can. I did the same thing.
    Also, by default Time Machine will not back up what you have on that extra partition. You can make it so that it does if needed (Would be a bit overkill if you did).
    I actually have 3 partitions.
    1 is for Superduper (when it's Leopard compatible).
    2 is for Time Machine.
    3 is for other storage.

  • Should I create a partition on external drive for iTunes music?

    ...or will it create it's own space outwith my backup stuff?
    (Secondary question: would moving my iTunes music from internal to external drive noticably improve performance of my Mac? I'm using about 135GB of a 250GB drive, 60GB of which is in iTunes Music folder)

    Should I create a partition on external drive for iTunes music? or will it create it's own space outwith my backup stuff?
    I see no good reason to create a separate partition unless you're backing up with Time Machine. TM prefers to have it's own volume, so in that case partitioning would probably be a good idea.
    would moving my iTunes music from internal to external drive noticably improve performance of my Mac? I'm using about 135GB of a 250GB drive, 60GB of which is in iTunes Music folder.
    No, probably not. As long as you're not getting the drive too full - opinions vary but about 20GB remaining should be plenty for most uses - you probably won't see any overall change in performance just from moving the iTunes content.

  • How can I partition an external hard drive with data in it? When I select the drive, the partition option is grayed out.

    I am having a problem partitioning an external hard drive with data in it. 
    When I select the partition, everything is grayed out.  I can't add a a partition for some reason.  When I asked this question to other people, they told me to select my partition "io" to do it from there.
    As you can see, I can't seem to partition it form there either.  I ran the Verify Disk utility but the volume came out okay.
    Any ideas as to what the problem would be?
    Thanks!
    Luis

    Select the main hard drive entry (topmost one.) Click on the Partition tab. Shrink the existing partition by grabbing the sizing gadget in the bottom right corner and pushing up until you free up enough space for your second partition. Be sure you do not shrink to less than the space currently occupied by your files. Click on the Add[+] button to create a new partition in the free space. Click on the Apply button and wait until the partitioning is completed.

  • How can I partition my external hard drive supporting mac OS in one partition and windows OS in another?

  • How do I partition my external hard drive without losing data?

    How do I partition my external hard drive without losing the data already on it? I've been using it with Time Machine on my old computer, but want to use it as a regular drag-and-drop type back up on my new computer. Is there any way to basically split the hard drive so I can still access the Time Machine backups on my old computer, but also be able to use it with my new mac? Thanks!

    If you reformat the drive all data is lost.
    The only way to save the data is to copy it somewhere else during the reformat.
    Drag & drop will not backup things correctly.
    I suggest you set up partition for each Mac and then point Time Machine to each of the partition for each of the Macs.

  • Windows and OS-X partitions on external drive

    Has anyone had any experience/problems with partitioning an external drive for OS-X and Windows?
    How about 3 partitons: HFS+, FAT32, NTFS. Or is that pushing my luck too far?
    I just received a new LaCie, primarily for backing up Vista Ult 64-bit, but if I can also use it for XP and OS-X that would be great.
    Any information will be most appreciated.

    I've used an external USB2 drive to boot XP, but it is a very dicy process, and not really worth it in the end. You can slipstream USB boot support into the XP installer, but when you are done, you won't have virtual memory support (no pagefile). It also requires that the internal drive be removed during installation (if XP sees an internal drive, it will insist on attempting to use it for a pagefile.)
    I've done the same with a 4GB flash memory card... but booting was hit or miss.
    I've partitioned my internal into 2 HFS and 1 NTFS partition, and that works very well when combined with MacDrive on the PC side. I'd stick with using the external as just a backup device or for OSX (works best with firewire.)
    I am not looking to boot XP although that would be nice, but simply to create a backup on the drive. I use Norton Ghost, which does allow a boot, or sorts, into the backup in order to restore a system.
    But more, I was interested in an NTSF partition for Vista on this MBP. I have not used Vista's built-in backup program so I don't know how it works, but my thoughts were to partition the 500GB into multiple partitions and use them for XP, Leopard and Vista and a CCC clone of my two Leopard OSs.
    Say, 3 HFS partitions for clones and storage, 1 FAT32 for XP and 1 NTFS for Vista, making 5 in all.
    The 2 HFS partitions are probably easy. It was the other two, FAT32 and NTFS that I was concerned with.
    I guess I will plug it in and use DU and see what happens. I have never used DU for NTFS or FAT32 on an external drive.
    As long as the drive is empty, I have nothing to lose and lots of experience to gain, right?

  • Why did my event library stopped showing my partitions and external drives?

    The event library stopped recognizing my computer partitions and my external hardrive. It looks like all events are available, just not organized by partitions and drives. The partitions and external drive still show up in the project library.

    I don't see anything like what you mentioned... " having a folder at the root level that emulates a camera, a folder with a name like DCIM or Private." Here are the windows showing the files on the user/HD, the tutorial image and the external drive. You can see the Final Cut Folders in each. In the past, I would see each of these in the Event Library so I could create a new event wherever I want to store it. I have also included a screen shot of FCPX showing the Project Library. It still shows the various devices, as I am used to seeing in the Event Library.
