How can I partition my external drive? (Time Machine)

Hello

Time Machine doesn't accept my external drive (Seagate Backup Plus thin, 2 TB). It takes the format: "Mac OS extended (journaled):

So I searched Google and found out, that I have to partition the external flash drive.

So I opened the disk utility. But then I can't partition:

What can I do? I really need to use Time Machine.

My laptop: MacBook Air, 13', mid 2013

Thanks for the responses,

Tlumi

The drive must be formatted with a GUID partition map, your's with a Master Boot record.

You can copy the content to the Seagate to your mac and format it correctly, partition and copy the data back?

  • Drive mapping: How can I get my external drive be mapped to F: (as he was once) rather than g: which is what happens when I turn on now.

    How can I get my external drive be mapped to F: (as he was once) rather than g: which is what happens when I turn on now.  I tried to unplug and power, reboot etc.  There is no F: drive connected to the computer.

    Go to start / Control Panel / administrative tools / computer management / "disk management and select external reader by clicking on it and then right-click on it and select change drive letter and paths."  It should show the letter currently assigned (G I guess).  Click the button change.  To the right will be a drop of drive letters box.  Go ahead and select F and click on OK.  That should do it. If F is not available, then it is used by the system for something else.  Check disk management to see if you can find it.  If it is not, and is not available in the list, I'm afraid, you will not be able to change until find you what is using drive letter F and remove it, or change it to something else.

    I hope this helps.  If this isn't the case, after return and we will try to understand what is using F or why it is not available.

    Good luck!

  • How can I partition my hard drive for dual boot Windows 7 and Windows XP?

    I installed Windows 7.  How do I get a partition or virtual hard disk the hardrive and then install a different OS, so that I can dual-boot between 7 and XP?

    I only know of the VHD, 7 has a "virtual machine" option or is a long process that requires a third-party software?

    Not longer than the partitioning of the HARD drive and install XP - actually quite a bit more fast I should think and gives you the ability to move from one OS to the other without having to reboot the machine. You don't need to have enough RAM but... If you find my answer helpful, please click the button "Vote as helpful"! Thank you! My Blog

  • I have my time capsule for base station; How do I set up just for Time Machine?

    For several years, I have used Time Capsule as a wireless base station more backup Time Machine. I back up a Macbook Air (single user) and iMac with 2 users (two computers running on OS X 11.5). With Comcast Xfinity I need is more like a base station. In fact, I reset my router Xfinity name and password to replicate what was the name and the password to my Time Capsule network. But, now that it's done I can't understand of set up time capsule without set it up as a base station. The installation guide seems to suggest that I could do so by plugging the ethernet cable from the modem to an ethernet port which is not the WAN port. But this configuration did not work. The installation wizard only took me the steps to set up a wireless network. How can I simply we it with Time Machine as an external hard drive?

    The installation wizard only took me the steps to set up a wireless network. How can I simply we it with Time Machine as an external hard drive?

    Simply turn off the time Capsule wireless.

    To do... Open AirPort Utility, click on the Time Capsule, then click on modify in the window that appears

    Click on the Wireless tab at the top of the next window

    Change the setting for the Mode of network on 'Off '.

    Click Update to save the changes

    But... and this is a big BUT... This work of pourrait ... and maybe not. Even if the backup on the Comcast network seems to be working, there will be no help from Apple in case of questions or problems of backup.

    The reason is that, so that your Time Machine backups be supported officially by Apple, users must save on the Time Capsule wireless, or connect their Mac (s) directly to one of the three ports LAN <>- on the Time Capsule using a wired Ethernet cable connection.

    If you decide to try the method of failure to load, please let us know how things work after a few days.

  • Is it safe to remove files from my macbook air now that I have set up my time capsule and backed up with time machine? My boot drive is full. How can I access files of my time capsule once they are deleted from my computer?

    Is it safe to remove files from my macbook air now that I have set up my time capsule and backed up with time machine? My boot drive is full. How can I access files of my time capsule once they are deleted from my computer?

    1 n ° put them on a regular external drive and the value of Time Machine to back up as well; the files you want to keep should be at least two disks in case one of them goes down.

    2. they will not be usable until the restoration.

  • Can't resize external backup Time Machine in the hard disk partition

    I have a Seagate Expansion to drive 3 that I use for storing files as well and Time Machine. Initially when I set up the drive, I allocated 350GB for the partition that I use with Time Machine.

    I use a 256GB MacBook Pro and Time Machine is now advising me constantly backup capsule is short of space. I have 2 questions:

    1. Disk utility does not allow me to resize the partition of Time Machine (I can only reduce the size using resize controls). Also, I can't delete the partition, because the minutes signed is grayed out (see screenshot) - However, I am able to erase this partition. What can I do to resize (and expand) this partition, or delete it and create a larger partition for use with Time Machine?
    2. What is the best size to send to the Time Machine partition in order to keep my Mac saved 256 GB?

    Thanks in advance!

    A drive that is mounted or shared may present as "Busy" that could prevent resizing.

    Try to disassemble the disc (with the assembly/disassembly button in disk utility) and see if it works better. Then mount it again before leaving the disk utility, or do a reboot to mount again.
