Thanks for choosing to take a look and help.
The problem is this:
I have a 1TB external hard disk with One encrypted partition(about 286 gb) - luks (I'll call this EP) One unencrypted partition(about 580 GB). - ntfs (i'll call this UEP)
The rest of the partitions were empty so they don't matter. I changed the UEP to "read only" in windows using
"diskpart attributes volume set readonly". It seemed to work fine without issues, but after a short while there was some error and my partition table went missing partition manager said the whole drive was unalocated. So too did gparted and fdisk.
I tried using testdisk and it found all the missing partitions, When I wrote the recovered partition to disk, the UEP returned fine, but the encrypted partition is now inexplicably downsized to 2MB.
Fortunately I did some partition data backup earlier when I was trying to convert this from GUID to MBR, before all this and have some sector data which may help in recovery.
The Pre-Crash data created by Partition Wizard is Here (line 37/39 are the partitions I speak of).
The Post-Crash data is here (noticeably start of 37 and end of 39 match the luks partition from the Pre-Crash data)
The LUKS partition is this one:
letter: * PartID: 7 Start: 137117696 End: 737118207 Size: 600000512 FsId: 255 Label: ClusterSize: -1 FreeSectors: 0 Primary: 1 Bootable: 0 BootVolume: 0 SystemVolume: 0
Is there any way to recover the LUKS partition while also keeping the 580 GB NTFS Drive?
I only need to recover the two drives that I have discussed here.
Please help me out with this.
