    I've recently had my MacBook Pros battery die and unfortunately I am unable to boot it, or if I can get it to boot it will shut its self off without warning after a few minutes, so while I'm waiting for a new battery I bought myself an iMac.

    Now I was running VMWare Fusion and Windows 7 on my MBP and had the VM on Bootcamp.

    I removed the drive from the MBP and plugged it in to an external chassis to get my data off it. The Mac data came across without a hitch, however the Bootcamp partition does not show up in disk utility, the mac partition just shows up and the other half is blank.

    Further diagnostics give me the same output.

    I purchased WinClone in hope to get it that way but it also cannot see it. I uninstalled all NTFS drivers and have been in contact with Russel from WinClone to try to diagnose the problem. He has gone above and beyond trying to help me with this issue but unfortunately I'm no closer to finding a solution.

    I managed to get my MBP booted for long enough to access the VM and it appears that the partition is OK, but for some reason I cannot access it when its connected to the external chassis. The MBP won't stay switched on long enough for me to get a backup going :(

    After doing some more digging I've tried some different tools and they can see the partition, but I am still no closer to accessing my data :(

    I'm hoping that someone out there might know why my MBP running Mountain Lion could see the partition, but my iMac running ML as well cannot see it when it is attached to an external USB connection. Or maybe someone can at least point me in the right direction to get access to my partition.

    I am a bit reluctant to mess with the partition as it still appears to work on the MBP...

    Thanks in advance.

    I'm probably 2 months late, but have you tried ReFit? I had the same issue as you and solved if using their partition tool. One additional thing I did was to use Gparted to delete a random Fat32 partition that was causing some confusion.

    After using Refit you may need to use Startup Repair from your original win7 installation DVD.
