SATA hard disk health

[SliMat]

I bought a second hand 6Tb SATA disk and before adding to my array I wanted to check it was healthy.

 

I ran a 1-pass preclear which was successful... interestingly the disk showed zero power-on-hours, implying it was new. I dont know if someone has managed to reset the S.M.A.R.T data!!

 

Anyway, I ran the extended self-test but it has been stuck at 10% for about 14 hours now;

 

 

I am assuming that this could be a bug and the test has finished as I was able to download the results. However there are a couple of readings which I would expect to be zero too and was wondering whether anyone who understands the S.M.A.R.T Report better than I do, can let me know if the attached report looks healthy? I am concerned as it shows a Raw_Read_Error_Rate = 148109952 and Seek_Error_Rate = 12147507 which to me seems that this is a faulty disk?

 

Any advice greatly appreciated. Thanks.

Extended SMART test aborted, but SMART looks fine:

Wow, I never knew that - thanks for linking to that post, its put my mind at rest, when I saw such massive numbers I was thinking that the disk must be on its last legs!

 

I dont think I have ever had an extended SMART test get past 10% - but if 24hrs is only reaching 10%, logically its going to take 10 days + to complete a whole test... so for me this isnt practical.

 

Many thanks @JorgeB for the valuable information - can you tell its my first Seagate 🤣
