I started using testdisk and I got this when trying to dig into MS Data:


Disk /dev/disk0 - 750 GB / 698 GiB - 1465149168 sectors (RO)


The harddisk (750 GB / 698 GiB) seems too small! (< 949 GB / 884 GiB)

Check the harddisk size: HD jumpers settings, BIOS detection...


The following partitions can't be recovered:

1. Have you checked any other MS Data entries for familiar files? The current NTFS header is corrupt.

2. Download GPT Fdisk from SourceForge.

3. Delete GPT#4 and add it with these start/size. Run dd to check NTFS header.

4. Re-create Hybrid MBR using Gdisk and 'r' (Recovery...) and 'h' (Hybrid MBR) and add 2 3 4 partitions (let Gdisk automatically include EFI) and mark 4 as bootable.

5. Reboot.

a. Confirm OSX works.

b. Confirm that Bootcamp shows up in Finder.

c. Confirm that you can see files in Bootcamp volume.

d. Confirm that Bootcamp shows up in Startup Disk.

e. Switch to Windows.

f. You may need Windows Startup repair, if you see a black screen. Please see http://support.microsoft.com/kb/927392 for details on W7 or use W8 install

media to repair startup.
