Hello to all members of the forum,
I have a broken Seagate 1TB drive, model is ST1000DM003-1CH162. It was used in a raid setup with a sibling of the very same model which is working perfectly well.
This unit instead has becoming increasing slower at read in the last few days with apparent no reason. I managed to salvage some documents and then I started tinkering with it to learn something about these kind of hard disk failures.
Currently the disk does not give any problem when I tried to zero fill it. The whole surface has been zeroed at a 100mb/s rate and even higher within a couple of hours with no errors.
When I try to read something back, it is stalling taking ages to read a bunch of sectors or even fail due to timeouts, no matter where I read them from the surface. Also when I try to interrogate the SMART status, it is still taking a lot of time to complete such simple operation which should not really require any reading back from the platters.
The drive is not doing strange sounds while it is seeking/reading, it just takes ages and stalls the SATA bus.
I use linux as my operating system, so I use all the command line tools like smartctl, hdparm and dd.
Here it is the full output of smartctl --all /dev/sda:

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
As you can see, there are many reallocated sectors: they grow a lot during the salvage operations.
What's happening to this disk? Could it just be the platters getting ruined or may rather be some kind of issue in electronics?
Thanks
