July 13, 201213 yr Heres my info Parity, power on 2642. Load cycle count 5855 Disk 1, power on 2646. Load cycle. 7448 Disk 2 power on 3479. Load cycle 9216 Disk 3 power on 1791 Load cycle 9539 I guess nothing wrong? So am i right when i say, if its not broken dont fix it. And i should leave it as it is and check again in one year? I would say yes it doesn't appear to be broke so don't fix it. Wait a while and check again. I've never touched mine and the only disk I have with high LCCs is an RMA'd EADS drive. The rest are about the same ratio as what you have 2 or 3 LCC to each power on.

This drive use to have LCC's higher than power on hours.
July 14, 201213 yr If it were me, I would let it go for now, just keep an eye on it. If it starts to accumulate rapidly, then I would rethink it. Sent from my SGH-T959 using Tapatalk 2
July 14, 201213 yr Typically the "skyrocketing" llc comes when a intermittent process keeps the drive from idling. The gap is big enough for heads to land, but not long enough to idle. So the heads land and take off literally a 100 times an hour and thousands of times a day. A small change in the value will solve the problem, no need to disable it. While 300 is often used, 30 or 60 will end the skyrocketing.
