Hello, I read all laptop related howtos and I tried to play with /etc/rc.config.d/rc.apmd.conf ( maybe I am wrong, I do not remember the exact name). I wanted my HD to slow down after a minute of inactivity when running on battery. I changed updated values to do sync and flush every 30 minutes or when buffers are at 70%. But I never got it working unless I switch to runlevel 2 and kill almost every running process :-( Anyone already manage to setup a toshiba laptop apm to spin down hd when not used??? Any tricks to avoid some programs to use disk so often??? Cheers! Pep Serrano <pep@serrano.net> http://pep.serrano.net PGP Public Key Fingerprint: 8534 A441 2AD8 AF16 926C FD42 C5D1 1F94
