Q: Bootcamp disk0s4 after Yosemite update (fdisk and testdisk info)

Hello everyone and Loner T,

 

I've been following the threads where similar issues were reported. I downloaded Testdisk and GPT disk. And I've been trying to follow the directions as best I could on my own to provide you with the information needed for support. I have a 40 GB Windows 7 Bootcamp partition on a 200 GB Macbook Pro Early 2008 HDD. Before the Yosemite upgrade, I have successfully added another 10 GB to the windows partition by shrinking the Mac OS partition. After the upgrade, the bootcamp was not visible as a bootable partition to be selected after restart and displayed as disk0s4 in Disk Utility. In addition, the 10 GB are now displayed as unallocated space. I have since downgraded to Mavericks 10.9.5 since Yosemite keeps on lagging on my maschine. I hope you can help me too recover the data stuck under Windows. Thank you for your kind assistance.

 

1.     I have run the following commands in terminal with the specified output:

  • diskutil list
  • diskutil cs list
  • sudo gpt -vv -r show /dev/disk0
  • sudo fdisk /dev/disk0

2.     I have followed the instructions in Bootcamp win8.1 autorepair fail after yosemite upgrade post to perform a deep search in Testdisk.


  • After analyzing the EFI GPT partition map, Testdisk returns:

 

Disk /dev/disk0 - 200 GB / 186 GiB - 390721968 sectors (RO)

Current partition structure:

     Partition                  Start        End    Size in sectors

  • QuickSearch returns:

 

Disk /dev/disk0 - 200 GB / 186 GiB - 390721968 sectors (RO)

 

The harddisk (200 GB / 186 GiB) seems too small! (< 250 GB / 232 GiB)

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

 

The following partitions can't be recovered:

     Partition               Start        End    Size in sectors

>  MS Data                390721535  488376311   97654777

   Mac HFS                390721924  391991459    1269536

 

  • Continue on MS Data returns:
