Hi, I wanted to let you know some of my recent experiences. I also had the HDD LED blinking slightly every two seconds and a bit stronger every few seconds on my desktop PC. Previously I had gentoo running with gentoo-kernel 2.6.30-r4 and did not observe anything like this. Then I installed kubuntu-11.10 and saw that blinking. I used "iotop -oPa" and the top entry was relatd to jbd2. I then tried "noatime", different commit times, reinstalled with ext3 or reiserfs, but everywhere the same slight blinking every 2 seconds. I also tried fedora 15 and 16beta live CDs, nothing changed. I do not observe this slight blinking, when my PC is in BIOS-Setup or when I boot an old Knoppix (does not run through for compatibility reasons as expected) and again, did not observe it with gentoo-kernel-2.6.30-r4. This is very annoying as it seems to be unclear what the real source here is (kernel > version XYZ?!, etc.) and if indeed it is actually a bad thing, which I would assume as I don't expect the LED to blink and thus represent an unneccessary activity, particularly when the system is idle. My system is based on an ASUS P5E (X38 chipset), Intel Q6600 with 2 (fairly new) S-ATA HDDs.
