97% seems very high.
$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 56G 7.4G 45G 15% /
tmpfs 1.5G 12K 1.5G 1% /lib/init/rw
udev 10M 940K 9.1M 10% /dev
tmpfs 1.5G 0 1.5G 0% /dev/shm
/dev/sda9 56G 35G 18G 66% /home/osamu/Desktop/data
As you can see, I am putting some parts of home in different partition.
There I have ISO etc.
I think 80% is high enough. (This is just guts feeling....)
