Hello.
I have old PC as router. It's K6 Athlon, noname motherboard with VIA chipset (AMI Bios and APM support). I needed power off, so I enabled APM and compiled modules in kernel. It works, but I have another problem. In router is old harddisk (quite loud) and I set in BIOS disk suspend after 3 minutes. Disk turn off, but after approximately 20 minutes starts run again, writes something (I can hear it) and after 3 minutes turns off again and after 20 min all again... I killed all daemons, but it didn't work. Somebody told me it's because linux write his logs and this stuff and gave me advice that I can put all logs into ramdisk. But I'm linux lame and make ramdisk is too difficult for me. I would spend a lot of time on it

Have any idea how let harddisk in suspend mode for longer time (and wake disk up only when I e.g. accessing computer via SSH or halting it)?

I hope I explain my problem clearly and exactly. Thank you for all ideas!

Look at file /etc/crontab. My system executes 'run-parts' every hour. Maybe your system has additional commands.

You can modify the times it runs in that file.
The time fields are: minute, hour, day, month, day-of-week (0 or 7 is Sun)

Thank you for idea. I simply killed cron process, but it didn't help. Then I killed almost all "suspicious" process and now it seems good - now is disk in suspend mode maybe 45 minutes. So I must probably figure out, which daemon(s) waking my disk up.

Is in linux some easy way, how find out which files were last modified?

And one by the way: I'm maybe old-fashioned, but it's still so amazing (and great) - I am somebody from Czech, I have some problem and somebody from Maryland in USA try to help me. Internet is really cool stuff Thank you KenJackson for idea again!

Sorry for being from Germany only (and even pretty close to the Czech Republic), but "find -mmin -3" will find all files in the current directory and above that have been modified at most 3 minutes ago. See "man find" for further options to that command.

I hope you were kidding about "German only". Aber Ich denke Ihnen für den Ratschlag. (I guess I made some mistake in it ;P)

Find is powerfull utility - I don't know about it. I used "find -mmin -3" in /var/log/ and changes were in ksymoops. I guess I must tune kernel logging.

Thank you for advices, gentlemen. Hope I can do it now.
