1002FAEX question

Hello.  Some time ago I found some multi zone error rates on my HD.  At start it was 3-5, then errors disappeared. But now I’ve got 92 errors. The drive have no problems in work, lifeguard diagnostic tools doesn’t shows any problem. It’s my system drive and I have no idea what to do. Should I ask about RMA or is it common error for drive which is installed as a system drive? Here is Victoria smart report:

But it still passed… What hardware configuration do you have on that drive? (MoBo, SATA mode, previous drive performance, single or RAID use, etc.)

The drive is connected as SATA and divided on 2 partitions. 100gb for system and second 900gb I use mainly for steam games. I can’t be sure but I think the errors had appeared after shutdown from power problems. Is the drive so sensitive for such things?
