So I have a suspect hard drive. What do you all use to do a comprehensive test on a Hard drive?

What leads you to believe there is an issue?

I use Seatools on most drives, but as noted, the drive manufacturers tool is the best option. Having said that, I've had drives start throwing SMART errors and even have read issues while the drive still passes testing. I'm at the point where once a drive starts showing SMART errors, it gets replaced.

I use badblocks 4 pass destructive test on all drives I receive home or work.

I am currently testing 2 10TB WDC externals at home.

Code:
jmd0 ~ # badblocks -wsv -b 4096 /dev/disk/by-id/usb-WD_easystore_25FB_4A454B5531344A5A-0:0
Checking for bad blocks in read-write mode
From block 0 to 2441609215
Testing with pattern 0xaa: done
Reading and comparing: done
Testing with pattern 0x55: done
Reading and comparing: done
Testing with pattern 0xff:  58.36% done, 74:02:11 elapsed. (0/0/0 errors)

and

Code:
jmd0 ~ # badblocks -wsv -b 4096 /dev/disk/by-id/usb-WD_Elements_25A3_4A4548373333554E-0:0
Checking for bad blocks in read-write mode
From block 0 to 2441601023
Testing with pattern 0xaa: done
Reading and comparing: done
Testing with pattern 0x55: done
Reading and comparing: done
Testing with pattern 0xff:  47.24% done, 74:01:56 elapsed. (0/0/0 errors)
should be done sometime lather in the week..

Before, during and after I look at the smart data:

Code:
jmd0 ~ # smartctl -A /dev/disk/by-id/usb-WD_Elements_25A3_4A4548373333554E-0\:0
smartctl 7.0 2018-12-30 r4883 [x86_64-linux-5.1.21-gentoo-20190831-2019-jmd0.comcast.net] (local build)
