Oto co Sun na to:

An increase of one block on the grown list after the format->analyze -

reserve block will be used.

Judging on the output sent in the case notes. A grown defectlist of
166 is not a reason to replace the disk. Only if the disk firmware
starts reporting the defectblock list is full or other defectblock
list errors the disk must be replaced.

The following error is also a reason to get the disk replaced: "ASC:
0x5d (drive operation marginal, service immediately (failure
prediction
threshold exceeded))"
