For all those paranoid about high LCC counts, like myself, here is the solution that worked for me:
1. Downloaded FDOEMCD.builder.zip from http://www.fdos.org/bootdisks/.
2. Added wdidle3.exe to CDROOT folder. ( http://www.synology.com/support/faq_ima ... didle3.zip )
3. Executed MAKEISO.BAT to create new FDOEM.ISO CD image file.
4. Burned FDOEM.ISO to CD and viola - it will boot to DOS and allows wdidle3 to run.
5. Disabled wdidle3 timer on all discs (I'm actually using WD20EADS)

Followed the steps, executed \D to disable intelipower logic, which did not disable it but set to 62
minutes instead. Well, works for me nevertheless.
As of this morning my parity drive of 12 days of in service had:
274 hours and the LCC of 4418, which comes down to 16 per hour.
Don't know what's causing that, as the other WD greens and the previous
parity WD green all have counts of 20-34. Perhaps some new firmware, or
the fact that I installed unmenu a couple of weeks ago...
Anyway, after firmware changes, it's been about 10 hour since then, the count
went up by exactly 1, to 4419. Seems to be working. Paranoia can go to sleep now.
