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 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 Code: sudo fdisk /dev/disk1 Disk: /dev/disk1 geometry: 60801/255/63 [976769024 sectors] Signature: 0xAA55 Starting Ending #: id cyl hd sec - cyl hd sec [ start - size] ------------------------------------------------------------------------ 1: EE 1023 254 63 - 1023 254 63 [ 1 - 409639] <Unknown ID> 2: AF 1023 254 63 - 1023 254 63 [ 409640 - 487368880] HFS+ 3: AB 1023 254 63 - 1023 254 63 [ 487778520 - 1269544] Darwin Boot *4: 07 1023 254 63 - 1023 254 63 [ 489048064 - 487725056] HPFS/QNX/AUX estDisk 6.14-WIP, Data Recovery Utility, May 2013 Christophe GRENIER <firstname.lastname@example.org> http://www.cgsecurity.org Disk /dev/disk1 - 500 GB / 465 GiB - 976769024 sectors (RO) Current partition structure: Partition Start End Size in sectors 1 P EFI System 40 409639 409600 [EFI system partitio 2 P Mac HFS 409640 487778519 487368880 [Customer] 3 P Mac Boot 487778520 489048063 1269544 [Recovery HD] Warning: number of heads/cylinder mismatches 255 (NTFS) != 1 (HD) Warning: number of sectors per track mismatches 63 (NTFS) != 1 (HD) 4 P MS Data 489048064 976773119 487725056 [BOOTCAMP] [BOOTCAMP ] 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.
