further sorry!
I have 3 DNS-323's, each with 2x 1T drives, and reach running ffp.
2 DNS323s don't ever come up with the pink lights - I've turned drive standby off!!
and the third device - my play machine (MPM)!
MPM has the two drive lights and the power light that go hard on pink and stay on when the drives go into standby, after attempting to access the drives, the lights go out and (about 5-6 seconds and you can here the drives click on), all go normal blue.
I also have to say that I recently loaded some new software, and it kept running out of room, as it was trying to store a rather large file (5meg) into /tmp, instead of /ffp/tmp.
My 'pink' lights appeared after that event, and still continues today (even after the /tmp problem has been fixed).
The relationship between the two? I think I may have been holding my tongue to the left of my mouth, as the wind blew from the east!
I have no idea - but that is what is happening - I have NO drive problems, (all tests) I have had a 1T drive fail after 2 weeks ( about two years ago now) and the light was flashing orange, replaced that drive, but not even in this new pink machine!
