Here goes, and please bare with me, as what I'm about to explain is and can be confusing.
I was cleaning out some old hard drivers using a tool provided by Seagate Seatool. I used the erase function and in the middle of it, I realized I was deleting my external 6TB drive (Also a Seagate). NOOOO< I panicked and cancelled/disconnected the drive.
Now the drive is not mounting at all, unable to initialize due to cyclic redundancy check (CRC) errors.
I've tried using Test disk, Fdisk, fixntfs and fsck to no avail in Ubuntu and gparted live boots.
I can't use Chkdsk in windows because no partition, and can't create partition because can't initialize.
Can't scan for data... I'm stuck and baffled at my stupidity but would like to recover my data if at all possible.
Any guidance much appreciated. I am asking in Ubuntu forum as I read that Linux tools might be my best option.
