Two questions about My Book Essential 2TB

inside is wd green rigth? but which: EZRX or EARX?

in green series heads park after 8 seconds, and 300 000 load/unload cycles is exceeded often after few months; in internal wd green is possible off this option, but in external too? and how to do it?

Yes, Green drive.  EARX in both of mine.  Not sure what else you are trying to ask.

Not very reliable drives, in my case.  And slow to spin up, but part of that is Win7 I am sure.
