How to partition an external hard drive Seagate

My old external HD Time Machine does not so I bought a 2 TB Seagate Backup more Portable Drive to replace it. It has been formatted for Windows but provided a configuration "NTFS_ Mac download for_ I ran. I'd like to partition the drive & use 1 TB for Time Machine.

When I go into disk utility, I cannot and select the Seagate HD, the choice of the Partition is grey and not selectable.

Any suggestion how to get this HD formatted correctly so that it is recognized in disk utility?

I guess that the external hard drive is formatted NTFS, so disk utility does not have to perform all the tasks in this topic. It you can't format it on some Windows system with the FAT file system? Once the FAT is made, the Mac of THE it reformats with HFS. However if you want to do with the above partition size (1 TB HFS and 1 TB NTFS or FAT) then can try you with a disk management utility.

  • What is an I / Q error? This occurs with the backups using external hard drive SeaGate

    We have two external hard drives; a 3Terabyte (don't know how it) Seagate and another whose name escapes me. On the Seagate, I get the message: backup did not complete due to I / Q error. What is I / Q error and how to fix this? If all goes well, not a complicated process.

    Thanks for any help. Hope I selected the areas to fix this, below.

    Hello

    I assumed that by I / Q error you mean error e/s? Run chkdsk on the drive Seagate:

    Start > Search bar > type cmd right click and select run as administrator

    High CMD should now be open, type the following:

    CHKDSK x: /r

    x involves the reader of your letter, so if your hard drive in question is the letter c, it would be:

    CHKDSK c: /r

    Restart the system and allow to run chkdsk.

    Kind regards

  • External hard drive Seagate

    Since the upgrade to Sierra, my Macbook will not recognize when my external 4 TB of Seagate hard drive is connected (no problems before the upgrade).  Another problem is that when I click on the Finder icon in the tray, opens a finder window, then whole screen turns black momentarily, then returns to the top with all the icons, but the finder window is now gone.

    You must update the Paragon NTFS driver. You can find the updated version on the Seagate support site at:

  • How can I make external hard drive, the restore points for windows 7

    Dear experts,
    My laptop Dell Studio 1558, pieces of 7,64 edition windows Home premium. I want to use external drive hard/Pen drives to achieve and many restore points. I have seagate Free Agent GoFlex 320GB.andTranscend JetFlash Pendrives 16 GB external hard drive. Is it possible to do in both of these external gadgets, restore points? Please specify the procedures in detail.
    Thank you very much.

    We must be clear on what you mean by "Restore Point."

    If by a restore point that you refer to the small key files backup made before a system change, it must be stored in the folder System Volume Information hidden on the hard disk the file is actually required, you can't edit this storage point (usually drive c :)). The only option you have is to set the amount of space to reserve for this purpose. Once you have defined, which then restore points are organized on a FIFO basis where when the space is too full for a new restore point the oldest is deposited.

    The alternative is going to be an image of the system. This will obviously be very wide for each backup, so if you want to do a number then you consider doing incremental backups. This way to make a complete and regular backup then or event based backup only the files that have changed. These backups are also defined as available points in the system restore utility.

  • Lightroom CC backup on external hard drive Seagate

    My Seagate hard drive is perfectly functional, make backups of several programs, including CClone, Joelle, and Time Machine.

    Yet when I recently tried to backup a catalog from Lightroom CC, I get the following error message.


    "Lightroom is unable to create a folder for your exports in the location you have chosen. Please select a different location. »


    Lightroom has no problem backup up to my 2 TB Lacie external hard drives.


    I use a Mac Pro with the latest version of the OS


    Can you guide me through this?

    This is the location you have chosen, IE the folder on the drive. Create a new folder on this drive called Lightroom backups and LR point in this folder to make its backups to. In Finder Right click on the new folder that you created and make sure that your username has both read + write permission.

    Also, it's a bad idea to have a single drive for Time Machine and store other files on this disc. Time Machine should have it own dedicated player to do back ups for that is not used for anything else.

  • How to find an external hard drive using bridge

    I use CS4 in a Mac. Due to lack of space, I transferred all folders of photos to an external hard drive Lacie. Now, I can find the Lacie with Bridge and find and open all folders of photos. But when I try to search by keyword, they are not found. How do I do that?

    You will need to reindex all files before that search works.

    I purge the existing cache and then perform a search in the top folder.  Select "Include Non-Indexed files" at the bottom of the search window.

    All files will be indexed, but it will take a while.  It start when you leave work on computer for awhile.

    Hope this fixes the problem.

    Hello

    I m not sure but I think to me it s no longer tied to your laptop and has nothing to do with Toshiba. Maybe you use the file system that can be read by other computers (Windows)?

    If you connect to the Windows computer, you can see the disk in disk management?
