External HDD became unallocated

Hi there, i removed external HDD case to use it internal now, but after removing case and use sata conenctor inside windows this just become unallocated without their before 3 partitions with lot of data inside it.

I tried using some partition recovery tools like MiniTool Partition Wizard, but this one it found the 3 partitions and space free/used exactly but when is recoverying partition it just crash.

Tried Aomei and Easus too but this both jsut say the disk is unsupported because sector is greater than 512.

Some advice how can i recovery this partitions or at least the data?

Thanks

Have you tried putting it back together as an External unit? maybe running in its original conditions will allow you to access the data you seem to have lost. I don't know about opening up external HDDs but I do know that internal-only drives have jumpers that can be set to change settings or make resets to the drive so I don't know if this erasure/dis-allocation was caused from that but it's something to think about. If you can get it to function normally as an External HDD try to backup your data first and then straight up format the drive when you put it back to be used as an internal drive.

Out of curiosity, what is the motivation to open it up and use it as an internal drive? you can get internal drives pretty inexpensively....

Yes i tried using usb again and keep the unallocated space. I tried partitionguru now, it fround my 3 partitions and show me all files inside each partition but only allow to copy big files to my another HDD if i purchase pro version.

Is there another software giving me option to copy files from lost partition but with free use?

No whole world is U.S or developed countries for cheap hardware. Things are not cheap here.

I would look up some other programs, the partition programs I use are Partition Wizard and PartedMagic... but I have never used them to do what you're doing as far as viewing and recovering files.

So just so I understand, when you plug in the hard drive via USB what happens? does it function, can you view the files on the drive that way?

No, is same like using internal sata now, unallocated space without any partition, only with Partition Wizard and Partitionguru both found my 3 partitions which was there before and find files, but Partition Wizard give no option except recover partition but cannot complete it while Partitionguru show me 3 partitions with all files inside it and i can select any of files to copy to another drive. But it only allow small files for free user, and bigger files only to Pro version.

Yeah that's strange... I would do some more looking around online, perhaps for a free program that can let you recover data from your drive. If not maybe just get the pro version of Partitionguru. If partition wizard keeps crashing, try running it directly from the disc instead of from the RAM (or the other way around, I think there is an option for what mode you can run it in)

Just curious, why did you want to make this hard drive an internal hard drive in the first place?

I would use it in another computer which have only USB2.0 and is too slow reading/writing in this case, internal with sata2 can push much more speed.

With your drives plugged in; complete this tutorial exactly as it states and post the picture.

Make sure it plugged into a internal sata and power.
