RE: Hard disk lock down.
Thanks for your advice.
I checked 'D' stats process numbers and compare with uptime's value..
yes, your opnion was right. :-)
but I couldn't prove what occurs problem.
There are'nt special messages in kern.log and dmesg.
I'm using 2.4.5 kernel.
What can I do check else?

Uptime is the sum of two numbers. One number is the average number of
processes in "D" state, the other is the average number of programs that
are ready to do CPU operations.
"D" state processes are processes that are blocked on disk IO. It sounds
like there is a device driver error in your system related to disk IO
that causes processes to get blocked, and that in this instance 37
programs have become blocked on disk IO.
I suggest that you run the command "dmesg" and/or check /var/log/kern.log
for information on what went wrong.
Also please note that we can't help you solve such problems without
information on what kernel version you run.
