... it's very slow because it tries to do something.

reallocated sector count rising (650 right now but it was lower)

current pending sector count and offline uncorrectable is rising too (faster).

It's just as the heads keep trying to read something continuosly.

I just saved everything so data is not important.

Is there something I can do (of course I can access it by serial port if needed).
Nothing important, of course I will not use it where data is important, but I am just curious
if I can have it stop doing this ... maybe reducing the size if the problem is in the final part of the surface.

TIA.

If you saved your data then bin the drive...or use it for parts. It not gona be a drive again.

Of course, I don't want to use it, but I am curious because it's the first time I see a problem like that.
My first guess is it find something on the surface and it tries to move the sector without success or something like that.

If you have very expensive firmware tools or at least a $350 SeDiv tool you can backup firmware tracks and attempt to run factory self scan but most likely drive will be to damaged to be re-cert.

You can for example disable bad head(s) and re-calculate adaptives and that can be of use to get some extra life out of the drive but ... soooner or later it will die anyway so buy a replacement drive and don't buy any Seagate F3 arch drive (any recent Seagate).

Good luck.


I have already replace it. It's just for fun and learn.
I successful recover all the data, so I don't think it is a head. One of the partitions
is a little swap partition. My guess is there is surface damage in that part of the disk (near the end).

Is there a way to see a realtime log through serial port?

Since I recovered everything, I don't think it's a head. I expected more damage if a head it's not working.
I think there is a little surface damage near the end of the disk, in the zone where there is a little swap partition.
