Help fix partition on RAID 5 using TestDisk

[ingovals]

I would I like to ask for help or some pointers on partition fixing a copy of a RAID 5 array.

I'll try to make the full story short so someone will bother to read it.

Seagate Blackarmor 400 with 3 disks, 2tb each in a RAID 5 setup.

It goes bad and I can't recover (This NAS is a piece of junk IMO), so I connect the disks to PC and find out disc 2 can't read.

I use ReclaiMe Free RAID Recovery on the 2 remaining disc and from what I understand everyhting looks pretty good.

I use the option to write array to disc. now I have a 4tb LaCie external HD and it warns me it will override everything and also a size warning (the size is exactly the same) but I try it anyway.

Now after that is done I do not see the drive anymore, and I find a mention that the partition table might be in the wrong place or something like that.

So I feel a bit out of my depth as I'm not very knowledgeable about partitions. Could anyone give me a nudge in the right direction?

This is what I see using TestDisk:

Select a media, excluding other disks, a C: drive and the 3 raid discs
Select a media

Disk /dev/sde - 4000 GB / 3726 GiB
Disk \\.PhysicalDrive4 - 4000 GB / 3726 GiB

It seems the LaCie is mentioned twice, so is the C:

I proceed on Disk /dev/sde - 4000 GB / 3726 GiB and it gives me EFI GPT as default option. I run Analysis on that.

Bad GPT patition, invalid signature.
Trying alternate GPT
Bad GPT patition, invalid signature.

I have no idea what this is. I can only choice Quick Search

Disk /dev/sde - 4000 GB / 3726 GiB - CHS 60800 255 63
Partition Start End Size in sectors
>P MS Data 63 968785530 968785468 [LaCie]
P MS Data 968785531 976754645 7969115 [LACIE SHARE]

Structure: Ok. Use Up/Down Arrow keys to select partition.
Use Left/Right Arrow keys to CHANGE partition characteristics:
P=Primary D=Deleted
Keys A: add partition, L: load backup, T: change type, P: list files,
Enter: to continue

Hmm this looks suspiciously like something that was present after LaCie initializing software ran originally (it was a new drive and the init created two drives/shares, one FAT 32 gb in size and a NTFS one.

So what is going on here, am I out of luck , what is my next step?

I assume your goal is to recover your BlackArmor data. But your Testdisk on /dev/sde shows LaCie partitioning. When you press P to list files what do you see?.... "Keys A: add partition, L: load backup, T: change type, P: list files,"
