    Perhaps you reformatted it HFS+? Windows has this thing about not liking HFS+ formatted disks. You can reformat it ExFAT with your disk utility program on your mac, that should solve this.

    It's probably formatted as NTFS. OS-X only reads, natively. I believe there are a couple of utilities that will enable read/write capabilities, but I can't remember the names.

    Another option is to move the data, reformat the drive as Mac OS Extended (journaled) with GUID partition table, then move the data back.

    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: Install NTFS-3G for Mac OS X (free)
    • Some have reported problems using Tuxera (approx 33USD).
    • Native NTFS support can be enabled in Snow Leopard, 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
