how to interpret SMART test 03 Aug 2020 17:21 #12199

Hi - I have a lat 2012 iMac with a 3.1 TB fusion drive. I recently received the warning "APPLE HDD ST3000DM001-ZIF2G0PJ is exceeding SMART warning levels". Also see screen shot attached and the SMART report (although I am not sure if either attachments are included)
If the report is not attached here are the problems which show triangles half way between pass and fail:

Extended health
Reported uncorrectable errors (187)
Current pending sector count (197)
Uncorrectable sector count (198)

I did a surface scan and found 122 bad blocks out of 5,860,533,168 blocks on the drive (about 3 Tb).
Are there any other scans that would be relevant to the report?

My question is what to do now. Although there are some bad blocks it is very small fraction of the drive. Should I repeat the SMART test at intervals? How far do the the pointers on the chart need to move for the drive to be replaced?

Thanks for your help

The drive should be replaced as soon as possible. Please see:

Surface Scan

You can get explanations of the SMART Test results in the manual for our Drive Scope program, available here:
