Since things seem to have veered off topic, I'll give the most likely
answer to your original question:
If you're hearing disk activity at a specific time every day, it's
most likely one of the periodic cron jobs. Most of these are
specified by files in /etc/cron.daily, /etc/cron.hourly, and /etc/
cron.monthly. You can disable individual jobs by removing the
execute bits on their scripts in those directories. You can also
change when they run by editing the "run-parts" entries in /etc/crontab.
I had to do this once when I had a server in my dorm room. The
server was at the foot of my bed, and it had a noisy old Kalok IDE
hard disk as one of its drives. The nightly updatedb job kept waking
me up, so I moved it to a time when I'd already be awake. ;)
You'll never get rid of *all* of the disk activity because there's a
lot going on behind the scenes in a Linux system.
