    I've got an external usb drive formatted as ExFAT which OS X finds unreadable:

    The drive was originally formatted by W7 however I really need it to mount on OS X without having to back off the drive to a second disk and reformat.

    The disk you inserted was not readable by this computer.
    Initialize... Ignore Eject


    System profiler reads as:

    Ext HDD 1021:

    Product ID: 0x1021
    Vendor ID: 0x1058 (Western Digital Technologies, Inc.)
    Version: 20.21
    Serial Number: 574D415A4139303137393036
    Speed: Up to 480 Mb/sec
    Manufacturer: Western Digital
    Location ID: 0xfa130000 / 6
    Current Available (mA): 500
    Current Required (mA): 2
    Capacity: 2 TB (2,000,396,746,752 bytes)
    Removable Media: Yes
    Detachable Drive: Yes
    BSD Name: disk1
    Partition Map Type: MBR (Master Boot Record)
    S.M.A.R.T. status: Not Supported
    Volumes:
    disk1s1:
    Capacity: 2 TB (2,000,395,698,176 bytes)
    File System: ExFAT
    BSD Name: disk1s1
    Content: Windows_NTFS


    Only thing that jumps out at me is that the drive's file system is listed as 'ExFAT' but the content is listed as 'Windows_NTFS'?

    Any ideas how I can get this to mount in OS X and why sys profiler is listing disparate file system and disk content?

    Thanks
