Can a use a partitioned external hard drive to create a disk image? I tried, doesn't seem to work using disk manager.

OK, it's very bad computing to use a backup disk for anything but a backup. The reason being is if/when the HD crashes you will have lost not only all your backup but the data files. While I commend you for wanting redundant backup, you really need separate EHDs for doing so. Format each EHD using Disk Utility to Mac OS Extended (Journaled) using the GUID parttition. When you connect, OS X will ask if you want to use that drive as a Time Machine backup drive, select yes and then let it backup. On the second EHD format the same way however do not use TM as a backup, this time I'd suggest an app such as SuperDuper or Carbon Copy Cloner to make a clone of the internal HD. Leave both EHDs connected and TM will backup new or changed files automatically on a hourly basis. The clone you will need to set to backup on the schedule you want. For example I have my SuperDuper EHD set to backup only changed or updated files at 2AM every day.
The advantage of a clone is that if the computers internal HD crashes you can boot from a clone and continue working, TM will not do that but it's great for keeping an archive of all files. So if you want a version of a file from many months ago, TM will help you locate and restore it.

  • Can I use a usb external hard drive larger than 2TB?  I have tried to use a 3TB but it shows up as 800GB.

    Can I use a usb external hard drive larger than 2TB?  I have tried to use a 3TB but it shows up as 800GB.  Even tred to reformat in disk utility but only shows as 800 gb as well.  It is a Seagate 3TB harddrive and enclosure.  Nothing on the Seagate site about it other than it says Mac os through 10.6 is supported  for larger than 2TB (might be old).

    You might have better luck in the Snow Leopard community. I'll ask the hosts to relocate your post.

  • Partitioned external hard drive for creating the USB bootable device

    Hi all,
    I want to install Win 7 on my Macbook Pro (OS X Yosemite 10.10.1) but I don't have an 8GB or larger USB flash driver. I do have an external hard drive of 500GB that I use for backup. So, I tried to create a small partition on this disk to create the USB bootable device required for the windows installation but apparently I'm not able to select any specific partition when the boot camp assistant ask me for the destination disk.
    Is that normal?
    Thanks.

    Yes, you can do that.
    Although you can buy a complete external drive system, you can also put one together if you are so inclined.  It's relatively easy and only requires a Phillips head screwdriver (typically.)  You can purchase hard drives separately.  This gives you an opportunity to shop for the best prices on a hard drive of your choice.  Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu.  You can find reviews and benchmarks on many drives at Storage Review.
    Enclosures for FireWire and USB are readily available.  You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports.  I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.)  You can find enclosures at places such as;
    Cool Drives
    OWC
    WiebeTech
    Firewire Direct
    California Drives
    NewEgg
    All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover.  Usually the only tool required is a small or medium Phillips screwdriver.

  • Can ipod be used as an external hard drive?

    Can the 80 GB ipod be used as an external hard drive if a certain section is partitioned? I bought the ipod with the most space for this purpose, for my music and a portable HD.
    What is the RPM on ipod HD?
    What is the best way of using the ipod as an external HD but at the same time making it compatible with itune for transferring music?
    Thanks.

    It is not recommended that you partition the iPod hard drive.
    You may render it useless as a music player if you do.

  • Can an Apple Time capsule be used as a external hard drive?

    Hello I have a 4th Generation time capsule and I've had it for some time now and never used it and I was wondering if it could be used as a external hard drive instead of just a back up disk. Also I am planning to install a copy of Windows 7 on my Mid 2011 21.5" iMac and I was wondering if Windows would recognize the TC as a external hard drive and would alow me to use it as such.

    It is not an external hard disk.. you cannot use it via USB if that is what you mean.
    It is now and forever more a Network drive. You can store files on it as a network drive.. with the following provisos.
    Store files on the TC.
    https://discussions.apple.com/message/24380694#24380694
    This is asked several times a day.. obviously people are struggling with their latest SSD being too small.
    The TC is not suitable for network file server.. but many people having no choice press it into service as such.
    It cannot be partitioned. It was and is and ever shall be a backup device for Time Machine.
    Major issues.
    1. No backup.. no way Time Machine can backup a network drive. No place to backup to.. So all your files will be at risk. And you will need to buy a third party like CCC to do backup.
    2. The TC cannot be partitioned and mixing TM backups and data is not great.
    3. The drive is slow to spin up and quick to spin down.. there is no controls.
    4. iPhoto in particular can easily corrupt its entire library with wireless networking causing a disconnection to one photo. Even if you do this;;; do not move your photo library... you have been warned!!
    5. iTunes will constantly lose connection to the library. The disk is too slow to respond.. itunes on the computer will constantly spit out errors. Even in the midst of streaming the TC can spin down the disk due to caching.
    6. Do not use any live files on the TC no matter what else you do.. if you edit files in whatever program the file must be on the local hard disk.
    7. The only suitable location for most libraries is a computer. You can plug in an external hard disk.
    Read pondini for some work arounds.
    Q3 here. http://pondini.org/TM/Time_Capsule.html
    Windows can also use the TC for files. Much the same warnings apply.

  • Can this device be used as an external hard drive with a macbook pro laptop to use files on the airport?

    can this device be used as an external hard drive with a macbook pro laptop and use files on the airport time capsule?

    If you mean an AirPort base station other than the Time Capsule, it doesn't have internal storage.
    If you mean a Time Capsule, its internal drive can be used for regular file storage but shouldn't be; as with all drives, it'll eventually fail. You're better off using a standalone drive and setting Time Machine to back it up as well.

  • Time Machine: Can I use a smaller external hard drive with larger internal?

    Can I use a 250G external hard drive with and 500G unfilled internal drive with time machine? Or will time machine require I a 500G? I don't plan on filling the internal drive for a long time and don't want to buy a new external drive right now.

    Yes, but you are very likely to get in trouble very quickly.
    The problem is that TimeMachine saves multiple versions of any file modified, and if that file happens to be large, you can quickly fill up your TimeMachine drive such that it is throwing away older versions faster than you would desire.
    Also if your boot drive's storage usage gets even close to the 250GB external drive's capacity, TimeMachine is likely to stop working.
    If possible, I would suggest an external drive that is twice as large as your boot drive, or at least 1.5 times larger.
    I guess you could repartition your boot drive so it is smaller than your external disk so you would be less likely to use more space than could fit on the external.
    Personally, my opinion about backups is that much of my data is impossible to replace (family pictures, etc...), and spending money on backup hardware is a small price to pay for securing those memories. I also try to have it backup in more than one location in more than one way.

  • I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks

    I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks

    There has never been a reliable firewire ---> USB adapter suitable for external high speed storage.  This was a major issue when the MacBooks lost the firewire port a number of years ago (Apple subsequently brought it back).
    The only high speed port on the Air is the ThunderBolt port.  There are external ThunderBolt drive options out there, but they're somewhat more expensive than traditional USB/FireWire options.

    I have the system Library on a second internal drive and it is syncing with iCloud with no problems. Also the Media Browser it seeing it there.
    Only make sure, your external drive is directly connected and correctly formatted MacOS Extended (Journaled).

  • Can the iPod (5th Gen) be used as an external hard drive? (w/ no syncing)

    Dear Forum:
    Can the Ipod (5th Gen) be used as an external hard drive where I can manually (without syncing) transfer photos to the drive? My goal is to be able to transfer images from my MacBook (OS 10.4.11) to the Ipod and then erase some of the pics on my MacBook to save space; this will be something I'd doing when I'm traveling--I don't want to be carrying my desktop external hard drive with me.
    Naturally I don't want to sync the photos onto the Ipod because I'll be erasing photos to save space. By the way, I use Aperture 2 (with latest firmware) if it helps to know.
    Ideally, is there a way I can "see" the Ipod as an external hard drive, so I can move files onto it?
    Thanks,
    Steve
