Can I use the harddisk that I used for Time Machine on my previous computer on my new computer without deleting the old back-ups?

Yes.  See:

My only concern is that you may not have enough free space on the drive.

  • 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.

  • Can I encrypt a USB hard drive that's not for time machine?

    can I encrypt a USB hard drive that's not for time machine?

    Yes, if it has the GUID Partition Map Scheme, but only by erasing it and choosing a new format.

  • I am trying to update my time machine backup on time capsule, but time machine keeps trying to create an entirely new backup (evidenced by the 200GB backup size). How can I get time machine to modify my old backup rather than create a new one?

    It must have found the old backup corrupt.. so you will more than likely have little choice. You can archive off the old backup if it is still useful.
    You can also verify it. See A5 http://pondini.org/TM/Troubleshooting.html
    He also has some info on this problem. eg C13.

  • I recently bought a new laptop because my old one crashed.  The only backup I had for my music was on my ipod.  My new computer will not recognize the ipods music and I can't transfer anything.  What do I do???

    I recently bought a new laptop because my old one crashed.  The only backup I had for my music was on my ipod.  My new computer will not recognize the ipods music and I can't transfer anything.  It keeps asking me to sync the ipod to this computer, but I'm scared to lose all my music.  I want to transfer some of the music onto my iphone but I can't.  I'm very frustrated and wish I knew more about computers at the moment!?!?  What do I do???

    You will need the help of some sort of 3rd party software to help you copy the content from your Shuffle back to your PC.  Once you have done that, you can reimport this music into iTunes and configure it to sync to your new Shuffle.

  • What is the best online storage service for time machine

    what is the best online storage service for time machine?

    ds store wrote:
    There isn't any, the reason is TimeMachine is a backup of your entire boot drive, can be many gigabytes in size which Internet Service Providers only provide a fraction of upload speed compared to download speed so it makes online backups rather impractical for most.
    You can share some files via a service like DropBox between remote computers, but to backup your whole system it's better to have it stored locally.
    After all how can you restore your hard drive if OS X isn't running to get online?
    https://discussions.apple.com/docs/DOC-3045
    Why is local storage better than offsite? I had a house that burned down and can tell you from experience that local backup was totally useless.

    No, each drive is treated separately. Sorry!!

  • Can I use the same external hard drive for time machine and storing other files

    I have a 640GB external hard drive that I have been using for over a year for time machine backups.  My mac hard drive is now starting to fill up and I am looking to move audio, video and picture files to my external hard drive.  How do I do this without messing up my time machine backups?  Can I do both on the same external hard drive?  Do I just make new folders on the external hard drive to move the files I want?  Thanks for the help.

    If you move the files you will need to get another disk to back the files up to. You don't want to have only one copy of certain files (personal, professional etc.).

  • Can you use the same external hard drive for Time Machine backups and as an additional storage drive?

    I have an external HD that I've been using exclusively for Time Machine backups. I need to clear space on my hard drive, so I was thinking to move music & photos to an external drive.  Wondering if I can use the same one I have (which I'll aslo keep using for Time Machine) or if I need to get another drive. 

    Hi Jossydtaylor,
    Time Machine can use either an entire external disk or a partition of that disk:
    OS X Mountain Lion: Disks you can use with Time Machine
    http://support.apple.com/kb/PH11171
    You can use Time Machine with a Time Capsule, and with USB, FireWire, and Thunderbolt disks. The backup disk can be directly connected to your computer or be on a network. If the backup disk has been divided into partitions, you can use one of the partitions.
    If the disk is partitioned using the Master Boot Record (MBR) partition type, some partitions may not be available for use with Time Machine. The GUID Partition Table (GPT) partition type is recommended.
    For more info on partitioning, see this article:

  • Can I connect a 4 TB USB drive to the airport extreme and use it as a network drive for Time Machine

    Can I connect a 4 TB USB drive to the airport extreme and use it as a network drive for Time Machine

    Yes, if the drive is formatted in Mac OS Extended (Journaled).
    The USB port on the Time Capsule is under powered, so you may need use a powered USB hub with the 4 TB drive...even if it has its own power supply.

  • I want to use my 1TB Seagate Hard drive for time machine and transferring files from Mac to PC.

    For about a year I've been using my 1TB external hard drive for only time machine. To be honest, it wasn't until today that I tried to connect my hard drive to a PC and realize it isn't compatible. I read about partitioning the hard drive so that it can work both for time machine and transferring files between pc and mac. I'm not what you would call tech savvy, so I was wondering if I can get some advice on how to do this.
    Thanks in advance.

    To do it, you have to partition the hard disk, so you will have one partition for Time Machine and another one to store files and use them in a PC and Mac. To create the partition, follow these steps > http://pondini.org/OSX/DU3.html
    In order to read and write in the external disk on the PC, you have to select "MS-DOS (FAT)" as "Format". If you choose any other option, the PC won't be able to read your external disk. Apart from that, note that you can't use files bigger than 4 GB with FAT. If you want to use the external disk with files bigger than 4 GB, you have to format your new partition in exFAT, and you have to do it on a PC

  • If I don't want to use my Seagate hard drive anymore for Time Machine...How do I go about this?

    I want to use the external hard drive still, but not as my back up disk for Time Machine anymore. How do I make it so that my Macbook doesn't associate this specific external hard drive with TM when I plug it in?
    Thanks

    Missing a pretty big step here....  How does one install a new OS on an external drive?  You can't install an OS without first booting into an OS.  I don't have a disk to boot to, but have gotten as far as downloading the install software.  Perhaps the answer you should be providing is that I need to create an install disk somehow?
    Is not the current HDD in your MBP a boot drive?  If so and you have Yosemite installed, you can boot into the recovery partition.  From the 4 option menu you can use Disk Utility.  If you have the NEW HDD connected to the MBP it will appear in Disk Utility.  Click on that drive to format in Disk Utility>Erase.  After formatting, go to the 'Reinstall OSX' option and install the OSX onto the external HDD.  When finished swap the drives.

  • I have a iPhone that holds the majority of my music on it. However, I just got a new laptop, and I do not know how to get the music that is on my phone and on my previous laptop onto my new one. Please help me out here.

    I know that I could just burn all of my music onto a disk and then put it back onto my new computer, but I was hoping there was an easier way.

    Use your computer's backup to transfer your iTunes library from your old computer to your new computer per the instructions included with this link, or do the same with both computers networked in some fashion, which shouldn't be hard to do if both computers are connected to the same wireless network.

  • Is it not recommended to use a partitioned external hard drive for time machine?

    1. i hv a 1 tb seagate  back up plus hard disc ..,,i want to make partitions for  using it for time machine, mac, and window repectively . is it not recommended to use a partitioned drive for time machine? some where i have red that time machine wont be able to restore data from external partioned hard drive  in case internal hard drive crashes.
    2. if i use the seagate back up plus 1tb for mac only and use time machine to take backup (roughly 250 GB) , then the rest space i cant use to transfer movies, pictures from a PC
    3. how should i best use the seagate back up plus hard drive (not seagate back up plus for mac) in a way that i use it for back up , and to work with both mac and PC?

    I use a partitioned external drive for Time Machine as well as other things.
    How you partition it is a function of yoru needs.

  • I am having trouble installing.  downloaded Mavericks but it will not let me install to hard drive, says that is reserved for Time Machine.  I have an external hard drive, but disconnected that before download.

    I downloaded Mavericks but can't get past the install; it thinks my hard drive is reserved for Time Machine.  I have an external hard drive but dis-connected that before download.
    I have Time Machine turned off.

    Check to see if you have a file name Backups.backupdb on the disk drive.
    If the installer sees such a file it assumes that the disk drive is being used by Time Machine.
