It seems every time I begin to use my computer for more than an hour my HDD light begins to blink and it just won't turn off (meaning the HDD never stops spinning if i'm right). I decided to investigate this a little more and wanted to see what is using it currently. I decided to fire up iotop (a piece of software that shows you what is using the hard drive with a top-like interface) and this is what shows up at the very top:
TID PRIO USER DISK READ DISK WRITE SWAPIN IO> COMMAND
290 be/3 root 0.00 B/s 0.00 B/s 0.00 % 94.79 % [jbd2/sda1-8]
I honestly don't know what jbd2 is doing and why it is using 95% of the I/O. I find this kind of confusing expessially how it's not reading or writing anything to the disk. Side note that I built this computer myself so if anyone needs the specs of something I can normally call them off the top of my head
Again, I don't know if this is why the HDD light just won't quit blinking on my computer, but it's my only guess, and I did Google this problem and I did not get any relative results. If it helps, I am running Debian Wheezy (stable).
Thanks for anyone that helps!
