    From what I remember you can only save into a hard drive with Mac or Windows but not both, though you can still access files from both?

    For those of you who use both Mac and Windows, how do you handle this (external HDD)?

    I was thinking maybe I should buy two 4TB external hard drive, one for Mac and one for Windows.

    Search the forum, there is a lot of information! :mad: In short, yes. If you don't need large files (> 4 GB) use normal FAT, best compatible. If you don't want restrictions use exFAT (compatible with Windows7 and newer). However be sure to format to exFAT on a windows computer!

    You can partition one drive into two or more partitions, if you prefer. There are several formatting options for each partition. Format A Hard Drive Using Disk Utility (which is in your /Applications/Utilities folder)
    Choose the appropriate format:
    HFS+ (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive) NTFS (Windows NT File System)
    • Read/Write NTFS from native Windows.
    • Read only NTFS from native Mac OS X [*]To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
      • For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion and later)
      • For 32-bit Mac OS X, install NTFS-3G for Mac OS X (free) (does not work in 64-bit mode)
      • For 64-bit Snow Leopard, read this: MacFUSE for 64-bit Snow Leopard
      • Some have reported problems using Tuxera (approx $36).
      • Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
    • AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    • Maximum file size: 16 TB
    • Maximum volume size: 256TB
    • You can use this format if you routinely share a drive with multiple Windows systems.
    exFAT (FAT64)
    • Supported in Mac OS X only in 10.6.5 or later.
    • Not all Windows versions support exFAT. See disadvantages.
    • exFAT (Extended File Allocation Table)
    • AirPort Extreme (802.11n) and Time Capsule do not support exFAT
    • Maximum file size: 16 EiB
    • Maximum volume size: 64 ZiB
    • You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.
    FAT32 (File Allocation Table)
    • Read/Write FAT32 from both native Windows and native Mac OS X. [*]Maximum file size: 4GB.
    • Maximum volume size: 2TB
    • You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.

    Does this mean that you can or cannot transfer files that are bigger than 4GB for exFAT?

    Of the formats I described, only FAT32 has the 4GB per file limitation. None of the other formats has such a low limit.

    Ok, so as long as you format your Windows as exFat, you can seamlessly use Mac and Windows together when it comes to external storage?

    Yes, with the restrictions and exceptions listed in my earlier post.

    Read post #3 and the links. Not all Windows versions support exFAT, you can't use exFAT-formatted drives for Time Machine or Carbon Copy Cloner backups, etc.
