Disk Safe for Service After Unreadable Sectors?

I recently replaced a disk in my pool after I received the following alerts:

Code:
* Device: /dev/ada3, Self-Test Log error count increased from 0 to 1.
* Device: /dev/ada3, 8 Currently unreadable (pending) sectors.


After replacing I run Sparefoots burnin script to validate wether the old disk is really failing or not.

Bad blocks returned no errors and the short & long S.M.A.R.T tests all pass without error - which installs confidence in me that the disk is actually fine.

I have attached the results and would appreciate some help deciding if the disk would be fit for service again or not please.

Info:
  • Disk is a WD100EMAZ shucked from a My Book (10TB)
  • My disks are hotter than I would like them to be
  • I didn't burnin the disk prior to use (I was too lazy at the time - bad boy)
  • The device identifier ada3 & da9 was the same disk just using different HBAs
  • There are a few short tests run in a row as the server shutdown while running long test due to power loss to the UPS
  • Happy to provide hardware info if need be

Thank you in advanced.
