Hi
I have a Western Digital Red 2.5" 1TB drive (WD10JFCX) in my file server. I noticed today the Load_Cycle_Count parameter went from 5 to 6 even though all the power management features are turned off (APM level is 255) and the server's been powered on for weeks. It hasn't done this in the time I've owned the drive.

I was just wondering if any gurus here know why it might have done this, or if it might indicate a problem. I've written a bunch of Linux (Bash) scripts that automate regular SMART self-tests on the drive, and they have all passed, but I just assumed that disabling APM means the drive should never park the heads (indeed, the drive hasn't since I've owned it and has been powered on since it was installed in the NAS).

p.s. I'm not one of those on the bandwagon that you must at all costs disable the head parking otherwise it will kill your drive, I just want to better understand how the drive/firmware works

thanks
