I just bought a Seagate Barracuda 3TB disk To replace an older 2TB disk. So I copied all data from the 2TB one to the new one. I formatted the disk as NTFS first since I want to be able to use it from windows as well. The old was was 99% full and with a 13,8 Mb/sec transfer rate it took over 40 hours to copy all data. After that the new disk worked perfectly under Ubuntu, all data was fine. But when I restarted I got an error complaining about a missing MBR. Weird, I thought. I switched the SATA cables from my SSD, containing a dual-boot Ubuntu-windows with that from the new disk. Now, Both Ubuntu and windows start fine, but the new disk is not mounted in any of them. When I load disk management both OS show the disk split in six parts:
- 3,14 GB unallocated
- 914,50 GB primary
- 13,74 GB unallocated
- 867,17 GB primary
- 249,45 GB unallocated
- 746,52 GB unallocated
Edit: Just noticed the disk looks different in Ubuntu (the previous list is in Windows). Ubuntu says this:
- 112 GB Free Space
- 871 GB NTFS Partition 1
- 372 GB NTFS Partition 2
- 1,6 TB Free Space
Edit 2: when I run fdisk -l this is what it shows for my new disk:
Edit 3: found this post that pretty much exaclty describes my problem. However, a solution is not provided. Before I give in and just start over I would like to know how to prevent these kind of problems in the future

This doesn't look like a partition table
Probably you selected the wrong device.

Partition table entries are not in disk order
Edit 4: From this answer to a similar problem I learned about testdisk. When I install this I can browse the new disk without problems. Now all I need is to find a way to really fix the disk (with testdisk?)
Is there a way to get the disk working properly again? Because I really don't want to waste another 40+ hours.
