Hi there,

a few months ago I noticed, that my HDD has read/write performance issues but I didn't think about it that much.

After that there were Windows 10 error messages about some memory addresses being accessible. Right after that the error message "The request could not be performed because of an I/O device error" started popping up frequently. That was when I decided (I am aware that I should have started fixing the issue way earlier) to backup my data.
While drag & dropping the data the paste tasks would often abort; especially with large files (common clone/backup tools would not work with the HDD anymore).
In that whole process the performance of the HDD obviously declined until I wasn't able to perform any read/write task. Of course the HDD's behavior was to be expected as I was figuratively choking it to death.

Today I decided to give it a shot and plug the HDD back into my machine but the Windows Explorer would only show the drive without it's designation and without any actual access to data.

As I am really new to handling harddrive problems I would like to ask if there are diagnose tools that can help me figure out what the drive's issues are.

Here are my HDD specs:
S/N: S1E*
Model: ST2000DM001
P/N:9YN164-500
FW: CC4B
Date: 12525
Site: SU
Preamp: B3-O3 (I guess)

I am guessing there is a problem with the head stack assembly. Maybe someone has had some similar issues and can point me into the right direction.
I have also already been looking for some donor drives and would like to know if someone knows whether the follow two drives would be compatible. SN: W1E; PN: 9YN164-505: FW: CC82: Date: 13415; Site: WU and SN: Z1E; PN: 9YN164-302; FW: CC4C; Site: TK (does Site SU automatically mean that they have different head stacks?).

Any help would be fantastic and would be greatly appreciated. Thank you in advance!

Have a great day
Frane

Unless the HDD is clicking and spinning down, replacing the head stack assembly is the wrong first step. In almost 100% of cases with this model the issue relates to firmware malfunctions associated with the bad sector reallocation functions or the media cache. It's not impossible that you have a weak/failed read/write head, but even if that is the case the firmeware issue will also need to be addressed to have any hope at getting the data back.

If the data is worth more than a few hundred dollars, your best bet is professional recovery. With PC-3000 it's likely a quick fix. Here in the USA most cases like what you describe are solved for ~$450. But, you can easily DIY it to death and turn it into a lost cause if you try things without a proper diagnostic or proper tools/equipment/experience.

When plugged in the harddrive in question seems to sound like at it did when it was working properly. Not sure if it is that what you meant with clicking and spinning down.
As the PC-3000 is obviously unavailable to me. Is there a affordable and available piece of hardware that could fix the "almost 100% of the time" issue you mentioned?

Usually I would instantaneously get in contact with a proper data recovery company, but I simply cannot afford that and I need the missing data stat...

Again any help would be highly appreciated. Thank you!

Agree with all of the above.

easy. you need 3 things:
- proper diag
- proper tools
- proper knowledge
- (parts)

ok, that was four...

either one is missing the disaster is imminent.
These drives are famous of developing 'nice' rings on surfaces in a few minutes, if not catched in time.
