HDD GURU FORUMS

Hi, the performance of my hdd is extremely low, and according to several softwares the Smart is excellent, it does not have physical damage either.
So I think it could be a firmware error, but I couldn't find the correct firmware anywhere
I will appreciate any help or advice you can give me.
The serial number is Z1DCPES6.
Thanks!

Nope, firmware will not solve it.
With what did you tested it?
