A little update, I know it's a while ago for the last reply but as I have read the whole tread out of interest because of buying the 2.5" drives for my Supermicro chassis 8x2.5"
Ordered a few days ago a batch of 2.5" drives the: RED NASware v3.0, WD10JFCX - 68N6GN0, Firmware 82-00A82
The wdidle3 shows by default 300 seconds for the LLC counter.
The wd5471 tells met nothing to do, not even with the LLC counter set to 8 seconds instead of 300 [default]
Interesting was when changing the timer from 300 seconds to disable, it increased like mad when I was monitoring this with hdtunepro in Win7. In a few minutes it got hundreds of LLC counts added, I had to rush to shut down laptop and boot in dos. Set the timer back to 300 and all back to normal, no more increases in the LLC, it stopped at 600...
*** UPDATE *** I had to turn the power off after disabling the idle3, that seems to be very important.
Hope this helps someone to disable this counter by default for these drives without checking it!
what does it mean? wd5741 is unuseful and I'm obligated to use wdidle3 with hdd link to sata of motherboard? somebody can help me?
