Disk showing errors, but passed extended smart test, does the disk still need replacing?

[ezzys]

An old 2TB drive started showing errors and they have reacurred again after a reboot at the weekend. I have run an extended smart test and is passed (attached). What does this mean? Is the drive okay or should it be replaced.

 

I have bought another 2TB drive as it was cheap so can replace, but want to know whether the drive is knackered or it could be pre-cleared and used again?

SMART test passed, but it's also showing some UNC @ LBA errors, give it it another chance, also a good idea to replace/swap cables first to rule that out, then if there are more errors with the same disk consider replacing.

Thanks changed cabels and appears to be going okay - will monitor and change if I get anymore errors.
