Thanks so much too all for the input.
When trying to mount the drive i get the following error:
wrong fs type, bad option, bad superblock on /dev/sda,
missing codepage or helper program, or other error
in
dmesg -w

when i try to mount the Drive instead of a partition i get the following error (in demsg -w):

@nachoparker am I approaching this wrong, or is the drive a lost case?
It would be really awesome to be able to save the data on the drive…
I assume that the error occurred due to an unavoidable power loss as described here:

PS. Sorry if this causes you to hit your head in disbelief… I’m fairly new to diving this deep into HDD architecture.
