I just bought a brand new Seagate Expansion Desktop Drive (2TB) and am trying to work out how to format it. I want to move all my photos and movies to it from my laptop so i have more space. I have a Mac OS X 10.5.8 laptop but i also wanted to make sure it was compatible with other Windows computers in case i need to use it on someone else's PC.


A friend in IT said i don't need to format it as it allowed me to drop files onto the hard drive from my mac and he could view the file on his windows laptop. Could someone please clarify if i need to format it or not?


If so, I've read through a few posts over the net and i am getting confused with the different format types.


Any help would be much appreciated.


Thank you!

MacBook, Mac OS X (10.5.8)

    He/she's right. If you can copy files to the external drive from your Mac and he/she can read the files in a PC, everything is OK and you don't have to modify anything. It probably means that the external drive is formatted with FAT32, a filesystem compatible with Windows and OS X. The only bad part of FAT32 is that it doesn't support files bigger than 4 GB, but apart from that, it works fine. NTFS and exFAT fix this problem, but exFAT isn't compatible with your Mac OS X version and OS X can't write in NTFS drives.


    As I told you, you don't have to change anything

    Thankyou so much for the clarification! I just saw on the website where i bought it from (http://www.jbhifi.com.au/computers/storage/seagate/expansion-desktop-2tb-sku-886 87/) that the system requirement are "Windows Vista, Windows XP, or Mac OSX 10.4.8 or higher" which is fine for my mac. They just excluded mac as a compatibility option on the box and the staff member told me all i need to do is format it.


    I have encountered a new problem though and think it may have something to do with my friend pulling out the hard drive from my mac and i think he may have done it on his laptop without ejecting safely also. After plugging into my mac yesterday, then my friend plugged it into his windows laptop. Today, i plugged it back into my mac and a pop-up occurred saying:


    NTFS-3G could not mount /dev/disk1s1 at /Volumes/Seagate Expansion Drive because the following problem ocurred:


    $LogFile indicates unclean shutdown (0, 0)

    Failed to mount '/dev/disk1s1': Operation not supported

    Mount is denied because NTFS is marked to be in use. Choose one action:


    Choice 1: If you have Windows then disconnect the external devices by clicking on the 'Safely remove Hardware' icon in the Windows taskbar then shutdown Windows cleanly.


    Choice 2: If you don't have Windows then you can use the 'force' option for your own responsibility. For example type on the comman line:


    mount -t ntfs-3g -o force /dev/disk1s1 /Volumes/Seagate Expansion Drive


    Or add the option to the relevant row in the /etc/fstab file:


    /dev/disk1s1 /Volumes/Seagate Expansion Drive ntfs-3g force 0 0

    From what you say, it looks like your external drive is formatted with NTFS but you installed NTFS-3G in order to be able to write in the external drive. I used NTFS-3G in the past and I decided to use another filesystem because that app gave me a lot of headaches.


    The message you are receiving is related to the fact that your friend ejected the external drive without doing that safely, so NTFS-3G is showing that window. To solve that, just open Terminal (it's in /Applications/Utilities) and copy this command:


    mount -t ntfs-3g -o force /dev/disk1s1 /Volumes/Seagate Expansion Drive


    Another option is to connect the external drive to a PC and eject the disk safely

    I finally got it to work on my mac. I had to connect it to a windows laptop for it to eject properly. I had some trouble getting 'choice 2' to work properly.


    Just so that i have this right- i should click on Disk Utility-> click on my external hard drive, click on partition on the right tab, select '1 partition' under volume scheme, name my volume, select MS-DOS (FAT) and then click apply?


    If this is correct, are there more steps after this?

    That's correct if you want to format the external drive with FAT32. If you have files inside the external disk, copy them to the Mac before

    Perfect! I loaded the seagate files back onto the drive. I don't need to run setup.exe do i? I can just load files on from now?


    That actually wasn't that hard and it didn't take that long to partition 2tb.

    You don't need that file. Note that you can't open exe files in OS X
