    Was that USB thumb drive used on a PC and formatted by it before?

    If so, it is probably formatted in NTFS which a Mac cannot write to. You'd need to go into disk utility and format it as FAT32 or ExFat for it to be usable on both windows and OS X.

    Be aware that formatting a drive erases all the data on it, so it's a good idea you copy over what's on there to your computer before doing this.

    Actually, there are alternatives to formatting it, since Mac OS X can be made to read/write to NTFS.


    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 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
