Error while trying to check with fsck.

FAILURE - WRITE_DMA status=41&lt;READY,ERROR&gt; error=10&lt;NID_NOT_FOUND&gt; LBA=12078

Probably, it occurs even when system just works.

FreeBSD 8.3 on Virtual Machine.

There are a lot of such error  occurs.

Is there flash media under the hood? It is very unhappy when you read sector that was never written.

Also in my host computer /home/nn/.kde/share/dolphinrc is for reading.
When I try to change it's mod it says : read only file system.

Also, now, when I try to boot to virtual machine it says "read-only file system" and throw me to the rescue mode to the /bin/sh intepreter.

Probably, these problems have same nature.

It means that your disk is faulty. Boot in single mode, run smartctl -a /dev/sda (where sda is your disk)
and seek replacement, then save as much data as possible.

I have started smartctl -t long /dev/sda
So, after a few hours. I should provide you smartctl -a , so you can look up the values and tell whether something wrong, do I get the workflow right?

smartctl -a /dev/sda > /tmp/smartctl.txt

gheist, Could you explain the overall structure of smartctl report?

I see
Completed: read failure?
It doesn't sound very good.
Okay, seems to me shopping is unavoidable?

Yessir - go shopping.
Then clone disk (dd if=/dev/old of=/dev/new bs=4k(or more) conv=notrunc,noerror)
Then boot fedora install disk, jump to command line and run fsck (some data is lost, but most will be back)

Old disk:
rewrite it with zeroes (dd if=/dev/zero) - some manufacturers cheat and reset bad sector numbers, so it makes good second hand drive for somebody else...
