While running either Reflect V6 Workstation or Server, I've run into a very odd problem.  Particular drives, either internal or external, show up with very erroneous partition information.  One external drive shows up some times with 6 partitions, of which only the first two actually exist.  The remainder of the partitions are outside of the actual size of the drive.  The drive has been formatted several times in Windows 7 and in the Win PE boot disk, but it always returns to this state.  

Additionally, I'm deploying images to new SSDs.  Of 4 brand new Samsung 850 PRO 512GB SSDs, one is also exhibiting the same behavior.  Reflect in the PE environment is showing the drive to be 16TB.  I have successfully applied the image to the drive by manually setting the partition sizes.  Everything appears to be working properly.  I'm just wondering if anyone else has run into this problem and knows a better solution than just getting it to "work".

Hi 

Thanks for posting. This is caused by a corrupt GPT header causing the GPT partition table to erroneously report  partitions.  Running utilities that don't understand GPT disk format and attempt to write MBR track 0 will corrupt GPT disks in this way.  Do you have any old disk utilities installed on your system?

1. Download FixGPT.exe and save to c:\    http://updates.macrium.com/reflect/utilities/FixGPT.exe
2. Open a command prompt with elevated privileges and type:
cd c:\
FixGPT.exe 0

Note: Replace '0' with the disk number of the problem disk. This is the disk number as shown in the Windows Disk Management Console, which is 1 less than the disk number shown in Reflect. 

After completion please start Macrium Reflect again and check the partition layout for the disk. 


Kind Regards

Nick - Macrium Support

I will try the suggested fix and post the results.

The new SSDs have not been attached to any system other than the system booting directly to the Reflect Win PE rescue disk.  The external drive has been bounced around being used for backing up or transferring files and images.  Its initialization was on a Server 2008 machine.
