Hi

 

I moved continents. Before I did that, I put all my important data onto USB disks, three of them each the same, and packed them each in different boxes.

 

Smart, huh?

 

Yeah, nah. I used Windows 7 x64, GPT format, robocopy. Nothing unusual. After that, I reformated the PCs and sold off all the excessive gear, so I only have these three disks, now. When I got here, I bought a new laptop, plugged n the disks and I now have 'GPT Protective Partition' as the partition type and I am unable to do anything. All options are greyed out in Windows and Linux reports a corrupted GPT partition.

 

How do I get to access the data on each disk? I figured this was a simple process and one I took pains to make sure everything would be simple.

 

For reference, these disks are over 2TB, so I cannot follow the recommended process of convert to MBR....

 

Any help appreciated...

 

Thanks

 

 

 

Gund

testdisk is great at rebuilding partition tables I have found.

http://www.disk-partition.com/gpt-mbr/gpt-protective-partition.html ??????

 

CopyAndPaste: The problem was almost certainly caused by a USB enclosure that translated a disk's 512-byte logical sector size into 4096-byte logical sectors. This is explained in more detail here. If you're lucky, you might be able to restore the partition table by using gdisk on the disk attached in its original way. See the gdisk documentation on GPT repairs for general procedures. You'd need to read the backup partition table from the disk and hope that it's still intact.

Sorry after re-reading your original post:

Oh heres somthing interesting,

 

They cables were bad, it was just that the 2 t drive was formatted, and data written to it using the USB 3 cables. The other drive was formatted using a USB 2. I jut switched the data cables, did not get any other cables. Just something querky about how each works.

This fad of sector size translation is thankfully pretty much over now. But usually it's done so that legacy partition tables can see more than 2tb and work on well obsolete operating systems. Not sure why it would be there on a drive that shipped GPT.

Ok, as suggested in other forums I read through, the fix was to put the disks into a desktop that could handle more than 2TB and thereby remove the USB-SATA convertor, so any modern-ish desktop. I'm still not sure how this fixed anything and I really have doubts that GPT protective partition is actually an error or maybe it's just some misleading message....
