Partitioning a 1TB hard drive - need help!

i would like to partition a 1 terabyte external usb hard drive into the following partitions
1 partition to hold a bootable snow leopard installation (so i can reinstall via usb, install bootcamp, add stuff, etc)
1 partition to hold a tiger installation (for my ageing g5 imac)
1 (largest + what remains of the 1TB) partition formatted in ntfs to put the rest of my multimedia/documents to be read by a pc (running XP or windows 7), ps3 + xbox 360.
would appreciate some help here as i have no clue where to begin.
i am running snow leopard on a macbook. thanks!

The program you're going to need is called Disk Utility - it's under Utilities in the Applications folder in Finder.
There's a Partition tab in the utility, which is where you'll start. You'll see your external disc, which you can carve up into various pieces. It's all pretty self-explanatory from there on.

  • Partitioning My External Hard Drive - need some help

    Greetings,
    Recently, i have bought an external hard drive, then enclosed it with a casing and connected it through firewire 800 on my iMac 20" 2.0Ghz late 2007 model. what i want is , on my external hard drive, i partitioned it into two, then one partition for my mac, and the other is for windows. wherein windows partition can also be read/write from my mac, and vice versa on my windows;
    am looking for a suggestion on how to make the other partition, the windows partition to be read/write from my mac, and can also be read/write on my windows;
    Really appreciate any help; thank you in advance.

  • Upgrading Hard Drive need help with making it work.

    I have just begun copying my HD to a 120GB 2.5" SATA drive.
    I'm using Super Duper to copy it, and I understand it will be a bootable disk.
    Once it has completed copying, is there anything I need to do to make it the startup disk ?
    Do I make it the startup disk before I swap the hard drive out from within System Preferences ?
    Also, it is currently called Disk 2 - Will that become the name of my HD (currently obviously called Macintosh HD)
    If it is, can I then change the name ?
    Any help would be greatly appreciated
    Thanks

    SuperDuper will make it a bootable disk if that's the backup option you selected. Look at the SD feedback information. It tells you what it will do and will then show the steps checking off each one as they are completed.
    All you will need to do is remove the old drive and install the new one. It should be ready to go if you did everything correctly. This includes partitioning the new drive using the GUID partition scheme, setting the format type to Mac OS Extended (Journaled), and then Erasing the drive using the Zero Data option.
    Be sure to test the cloned drive before installing by booting the computer with it while it's in the external case.
    You can rename the drive anything you want.

  • Can I partition a 1tb hard drive and also run time machine on that hard drive

    I have a 1TB external hard drive which s currently running for Time machine only.
    I was hoping to be able to partition the EHD so that 500GB would be for the Time Machine side and the other 500GB would be used as an ecternal storage [ a friend of mine has just lent me a 250gb hard drive with a load of tv series which i want to be able to copy].
    Can anyone tell me if this is possible and if so how do i do it.
    I know that Time Machine is running now but I don't mind starting all over again.

    Yes it is possible, but it is generally not a good idea. That being said, if you decide to use the EHD for another purpose, partitioning it is the best solution. How big is your internal HD? It is recommended for a TM partition to be 2X as large as your internal drive, and it must be at least the size of your internal HD in order to be used.
    In order to partition:
    1) Connect the EHD
    2) Open Disk Utility and select the drive
    3) Click the "partition" tab and drag the original partition to its desired size.
    4) Click "Apply" to create the secondary partition.
    Resizing the TM partition will not erase it.

  • Question about hard drive, need help lol.

    Hey I'm kinda new to the MacBook world and have a stupid question. I am getting a late 2009 MacBook unibody (white polycarbonate, model MacBook 6.1... I believe) I am switching the original 250gb 5400 rpm hard drive out for a Seagate Momentus XT 750gb 7400 rpm hybrid hard drive. I want to keep everything on the original hard drive and just pop the new hard drive and start fresh with Snow Leopard. I'm going to purchase the SL cd from apple but I do not have the original  grey start up cd that came with it (my girlfriends little sister lost it). Do I need to call apple for that cd in order to start fresh on my new hard drive or is everything I need on the SL cd?
    Also how do I go about wiping the whole computer when I put the hard drive in and use SL? I want to essentially have a completely clean laptop with a new hard drive.
    Thanks for your help in advance.

    The SL disc you get from Apple will do everything you need. When you nstall the new hard drive there will be nothing to wipe, the drive is the only piece of that Mac hat stores anything so you don't need to worry about that. Post back and let me know how that hybrid drive works out....I'm interested.

  • BIOS doesnt recognize SATA connected Hard Drive- need help flashing bios from bootable USB

    hi
    I have an envy laptop running InsydeH20 bios rev f14.
    the bios doesn't recognize the internally connected hdd/ssd.
    I have heard that with insyde bios', sometimes you have to unlock 'secret capabilities' to recognize hardware incl internal hdd.
    but I am just trying to reflash my bios.
    the problem is that I cant get into windows because it doesn't recognize my hard drive and windows doesn't allow insallation to usb connected drives.
    I downloaded the patch from hp.com for my product and it actually has an option for making a bootable USB for use on the actual system, and I did this. the instructions are to just restart my computer with the bootable usb. I have tried Legacy support on and off, neither updates bios.
    I highly doubt it has anything to do with the physical sata connector.
    basically I need to flash my bios from bootable usb. I have done some research about making a bootable dos usb etc etc but I don't know what program to even run and how..
    this is a link to my product:

    hi
    I need to flash the bios of my system. the bios is not recognizing hardware and cannot boot into windows to run the bios flash for windows.
    on my other comp I ran the bios update patch and chose ' install to bootable usb ' so that I could use it on my system.
    cannot run on my laptop. tried booting from the media. tried allowing 'legacy' compatibility.
    im running insydeH2O rev f14 right now.

  • Upgrading hard drive, need help!

    I found a good deal on a hard drive at best buy, but I'm not sure it's right... I can't a model number on any of the mac specialty sites. Could someone check out my link and tell me if it will work and if it won't what I need to be looking for in the specs? Thanks. (the more opinions the merrier!)

    I have just upgraded my iBook with the same hard drive.
    The only issue, this happened when upgrading the hard drive on my iMac as well.
    I have the MacOS 10.3 restore dvds for both computers. When you boot up from the DVD. Format the hard drive on Disk Utility. The Drive formats but isn't able to have the OS saved to it via installer. Leave your DVD loaded quit installer turn computer off. Turn on computer you can now save the OS to your hard drive.
    Might be different with MacOs 10.4 restore DVDs

  • My girlfriend reformated her iPod as a Hard Drive, need help.

    My girlfriend reformated her iPod as a Hard Drive by accedent when trying to format a Mac iPod for Windows. How does one make this iPod be reconized as an iPod again rather then as an external HD? The iPod in question is a iPod nano, 16 GB running iPod software 1.0.4

    When the iPod is formatted by Apple's installer software and disk mode is enabled it will mount as a single FAT32 partition...you can store stuff on it given the remaining size left over from your music/photo files.
    Sub-partitioning and playing file/formatting games on your own is unsupported and will have unknown behavior....you can try it and rerun the formatter if it gets scrwed up, but the iPod is music device first, not a generic drive that you're supposed to monkey with.

  • Replaced hard drive: need helping getting songs off ipod to itunes

    I recently had to send my computer into apple for repair, needless to say they had to replace my hard drive so i lost all of my music. However it is still on my ipod, so i was wondering if there is a way to transfer it from my ipod to my computer

    Connect your iPod to your computer. If it is set to update automatically you'll get a message that it is linked to a different library and asking if you want to link to this one and replace all your songs etc, press "Cancel". Pressing "Erase and Sync" will irretrievably remove all the songs from your iPod. When your iPod appears in the iTunes source list change the update setting to manual, that will let you use our iPod without the risk of accidentally erasing it. Check the "manually manage music and videos" box in Summary then press the Apply button. Also when using most of the utilities listed below your iPod needs to be enabled for disc use, changing to manual update will do this by default: Managing content manually on iPod
    Once you are safely connected there are a few things you can do to restore your iTunes from the iPod.
    The transfer of content from sources such as songs imported from CD is designed by default to be one way from iTunes to iPod. However there are a number of third party utilities that you can use to retrieve music files and playlists from your iPod. I use Senuti but have a look at the web pages and documentation for the others too, you'll find that they have varying degrees of functionality and some will transfer movies, videos, photos and games as well. This is just a small selection of what's available, you can read reviews and comparisons of some of them here:
    Wired News - Rescue Your Stranded Tunes
    Comparison of iPod managers
    Senuti Mac Only
    PodView Mac Only
    PodWorks Mac Only
    iPodDisk PPC Mac Only (experimental version available for Intel Macs)
    TuneAid Mac only (iPhone and iPod Touch compatible)
    iPodRip Mac & Windows
    YamiPod Mac & Windows
    Music Rescue Mac & Windows
    iPodCopy Mac & Windows
    iRepo Mac & Windows (iPhone and iPod Touch compatible)
    iPod Access Mac & Windows (iPhone and iPod Touch compatible)
    If you have any iTunes Music Store purchases the transfer of purchased content from the iPod to authorised computers was introduced with iTunes 7. You'll find details in this article: Copying iTunes Store purchases from your iPod or iPhone to a computer
    There's also a manual method of copying songs from your iPod to a Mac or PC. The procedure is a bit involved and won't recover playlists but if you're interested it's available on page 2 at this link: Copying Content from your iPod to your Computer - The Definitive Guide
    Keep your iPod in manual mode until you have reloaded your iTunes and you are happy with your playlists etc then it will be safe to return it auto-sync. I would also advise that you get yourself an external hard drive and back your stuff up, relying on an iPod as your sole backup is not a good idea and external drives are comparatively inexpensive these days, you can get loads of storage for a reasonable outlay.

  • CS3 on old hard drive need help to activate

    My HP motherboard failed (manu defect) the hard drive is fine and has my adobe CS3 suite on it. I bought a new laptop and tethered the old hard drive to my new computer. I try to start the cs3 but a pop up says my computer lacks an adobe llinguistic code?? I moved and lost the serial on the case. How do I use my cs3 from the old hard drive?

    You probably do not use it from the old hard drive vecause the program needs to be installed on whatever machine is trying to use it... even if you intentional;ly tried to install on a separate drive the program still needs to install some ellements on the main system drive.
    If you check you Adobe account online you might find the serial number there if you registered the program.  You can download CS3 applications thru the following link: Download CS3 products

    Hi,
    Try the following.
    Remove the Windows 7 installation disc and shutdown the notebook.
    Tap away at the esc key as you start the notebook to enter the Start-up Menu.  Insert the Windows 7 installation disc.  Select the Boot Options menu ( usually f9 ).  Use the arrow keys to highlight the CD/DVD drive and hit enter - if prompted to 'Press any key to continue......', do so.

  • Hello, I need help to retrieve deleted information to partition an external hard drive. What should I do?

    Hello, I need help to retrieve deleted information to partition an external hard drive. What should I do?

    I'm not about the question, and giving you the right answer requires me to ask a few more questions.
    Do you want to retrieve deleted information for future usage, or to completely delete a partition? The latter is straightforward: simply erase the partition. The former is more complicated: it's very difficult, even using available commercial software, to recover deleted information. If the data is important, you may want to contact a professional like DriveSavers. It won't be cheap.

  • HELP I partitioned an external hard drive by mistake - how to undo???

    HELP HELP HELP
    I just bought a new WD 1TB hard drive (so now I have two) and wanted to partition in (1 partition) but by my stupid mistake I had chosen the wrong hard drive - so now about 1TB worth of music and films and photos (my entire iTunes and iPhoto library is gone - and do not have a back up). I did the partition with Disk Utility.
    Is there anyway to get it back???

    +*Stop using the drive immediately+* to stop further loss due to files being overwritten.
    You need specialized +Data Recovery+ software, or a service that performs the function. It's not cheap, and there are no guarantees.
    The app mentioned here most often is +Data Rescue 3,+ but I haven't used it myself, so can't recommend it over any of the others.
    Some of these have a free "trial mode," that will tell you if there's anything to be recovered, and perhaps recover a single file. For more, you have to pay the $$.
    You'll also need another drive to receive anything it can recover.
    PS. Will order a time machine after submitting this question
    You already have +Time Machine.+ It's part of OSX Leopard and Snow Leopard. It can back up to an external drive, or a Time Capsule (Apple hardware - combination of wireless router and hard drive), or a shared drive on another Mac.
    When you get to it, you might want to review these:

  • What's the easiest way to add storage to a mac mini. (1TB hard drive but only 32G of real storage). External device, internal or partitioning?

    What's the easiest way to add storage to a mac mini. (1TB hard drive but only 32G of real storage). External device, internal or is there some way to partition? I tried doing so but received a message that there wasn't enough free space to partition. Seems like a 1TB drive should have more storage than my Ipad

    Its worth confirming what free space you have on your drive: 
    go to:   Apple Menu > About this Mac >  More Info > Storage
    The bar chart shows how much free space there is on the drive:
    Please realise that partitioning does not create extra space so this wont help you.
    If your free space is less than 20 % you should get extra storage with an external USB or Firewire drive, any make or model will work.

  • I have 1TB hard drive i cant drag or sent to it although i can view it on my desk top do i need to format the hard drive ? please advise

    i have 1TB hard drive i cant drag or sent to it although i can view it on my desk top do i need to format the hard drive ? please advise

    If the format is NTFS, which it likely is, then follow Ralph's advice, but youmay also want to partition it with GUID partition table.
    In Disk Utility, select the drive, then Partiiton tab.
    Choose 1-partition from the popup menu.
    Click the Options button (it is only enabled if you change the partition layout, above).
    Select GUID partition table.
    Then, give the drive a Name and format of Mac OS Extended (Journaled).
    If you wish to use the drive with Windows, use MSDOS or exFAT. MSDOS will limit files sizes to 2GB. Some think exFAT is flakey.
