So, I accidentally initialized a NTFS Disk as RAID. I'm trying to recover my partition.

I can see my partition named "Archive" on list after quick search.

Code: Select all

The harddisk (1000 GB / 931 GiB) seems too small! (< 1664 GB / 1550 GiB)
The following partition can't be recovered:
     HPFS - NTFS          80885  25 37 202407 138 35 1952258048 [Archive]
     NTFS, blocksize=4096, 999 GB / 930 GiB

But I can't write it to disk.

So I try to change the controller mode in bios to AHCI instead RAID and now I can see a lot of relevant stuff even before quick search:

Code: Select all

check_part_gpt failed for partition
 4 P MS Reserved              1230848    1261567      30720 [Microsoft reserved partition]
Bad GPT partition, invalid signature.

 4 P MS Reserved              1230848    1261567      30720 [Microsoft reserved partition]
 5 P MS LDM Data              1261568 1953525134 1952263567 [LDM data partition]

Analysing by size, I think that LDM Data is my partition. I'm not sure if it was an extended partition before the mistake, but I'm sure that my partition was using the entire disk (at least, all the available space to partition).
On Advanced mode I can change these partitions:

Code: Select all

 1 P Windows Recovery Env        2048    1023999    1021952 [Basic data partition]
 2 P EFI System               1024000    1228799     204800 [EFI system partition]
 3 P MS LDM MetaData          1228800    1230847       2048 [LDM metadata partition]
 4 P MS Reserved              1230848    1261567      30720 [Microsoft reserved partition]
 5 P MS LDM Data              1261568 1953525134 1952263567 [LDM data partition]

But I don't know exactly what to do. I can change LDM Data type to NTFS or something like that?

On Disk Management on Windows, It's asking to initialize the disk but I didn't do anything because I don't know if it can help. The disk is show as Unknown, Unallocated and Not Initialized.

Please, any help is welcome. I'm trying to recovery it the entire week.
Thank you

You have to go through the list of entries and see which partition contains readable information that you would like to recover. In your case you would select partition number 5 and look if the "p"-key ("list files") is available and you would have to look into the partition to know if it contains the information that you expect.
If successful you could p.e. directly copy its content to another drive.

On Advanced I see only "Type" and "Image Creation" option.
On analyze I see only Quick Search and Backup.
After quick search/deeper search the message is exactly as my first quote

"The harddisk (1000 GB / 931 GiB) seems too small! (< 1664 GB / 1550 GiB)
The following partition can't be recovered"

there's no "list files" option.

This is how the screen looks like.
