Needing to rescue a drive

Support
1

Bad command results: In creating a gpt on a fresh disk the wrong drive letter was used and messed up my gpt. other than checking testdisk and checking to see I my partitions were fine (which all of them are), I have dne nothing else to /dev/sda.

dd if=/dev/sda of=/dev/sdc

this command made a copy of sda (a 1TB drive) to sdc (a 4TB drive). I have removed the 4TB for safety.
Current situation of /dev/sda:

Using gdisk I get this:

gdisk /dev/sda
GPT fdisk (gdisk) version 1.0.9

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: present

I can safely create a protective MBR.
When trying to recover all partitions as primary testdisk gives this result.

Structure: Bad. Use Up/Down Arrow keys to select partition.

Invalid partition structure.

Picking 4 of the partitions and writing can be done, then gdisk again returns with MBR only instead of protective.
I can pick all those partitions, but only 4 at a time. Each partition is fine and I can actually see all files and they are NOT corrupted.
Wishlist: Get MBR/GPT tables working with the partitions file systems without having to move things around. Other option would be to copy each partition onto another drive, fix the internal drive and move them back. Moving would be a trail as there are lots of links and specific permissions on individual files/folders that need to be kept.

I know the experts will say read the man pages. I have memory retention issues that make it very difficult for me to try and patch proper commands together. Give me clear example and I can easily figure it out. :confused: other when I have a brain cramp and put the wrong drive letter in.

Looks like a hybrid table… convert it to gpt:

sudo sgdisk --mbrtogpt /dev/device
3 
gdisk /dev/sda
GPT fdisk (gdisk) version 1.0.9

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: present

Recopied from above!
As you can see gdisk says MBR: MBR only and GPT: present.
Normally MBR: MBR only should read MBR: MBR protected. Problem goes back to how do I get those hidden partitions showing. They are there just need a proper table.
