Is my external drive healthy?

I bought Seagate Expansion 2.5" 2T portable drive.

This is the SMART pictures by different programs:

It passes long and short generic test in SeaTools but I am told by some user that this test is way unreliable, that it can pass even if drive has bad sectors.

Error scan in HD tune is OK.

Seagate support told me that portable drives are not reliable in SMART :"Additionally, SMART attributes are not applicable to external drives connected via USB. Since you have already run tests using Seatools, we believe the drive to be functional. You can try using the drive and let us know if there are any concerns"

Also I tried to update drive firmware but I couldn`t seems to find any firmware by my disk serial number . For that Seagate support told me this:

"With respect to your query about a firmware update, we would like to clarify that the hard drive is just a plug and play device and it doesn't require any firmware update. Please note that the essential drivers and updates for this drive will be supplied through an operating system and chip set drivers"

Some say that this is a complete nonsense, that you can read SMART throught USB.


I am worried about Read error rate, after short time that number fall from 84 to 83. Last night when I connected it Read error rate was 76 and when I done some read benchmark in HD tune it jumped to 81 and after one more read test it jumped again to 82.

This is in SeaChest from last night:

What do you think?

Seagate drives are known to report high read error rates under normal operation for some weird reason. That's not actually an indicator of a problem.

Example (ignore the spin-up retry count,):

If it passed Seatools it's fine

FYI. They won't RMA the drive

Ok, before use I just wanted to be sure that everything is alright. I will start using it today
I mean if Smart reading was right than Raw read error rate wouldn`t jumping around. I didn`t find any problem with drive yet.

Generally regarding other disk manufacturers if raw read error rate falls to 0 will drive fail or what? Som say if it falls to 0 that this is just unwanted value, that other smart value are more important and other say that disk will immediately fail. What is the truth?
