Sometimes my dmesg is flooded with these messages. It should be tied with my Asus DVD drive.

Are these messages malicious?

I expect they mean that the dvd disk has a problem. Try cleaning it.
If the dvd disk is looking clean it might be a issue with the dvd drive.

3

Malicious, Certainly not.
As stated above they indicate problems reading the disk, and the messages up to the 333 second mark are normal boot messages.

Clean the disk then try again.
Is this a bluray disk? if so then one may need to install the proper libraries to support reading the disk. If a DVD then one may need the libdvdcss package.

4

it is empty CD/DVD disk reader over SATA.

5

Empty?
Then of course it cannot be read or written.
To write it needs a blank or rewritable disk.
To read it needs a good disk with data on it.
If neither of those conditions are met then it will always produce errors.

6

An empty DVD drive is supposed to announce itself as empty

sudo cat /dev/sr0
cat: /dev/sr0: No medium found

and should not try to read a non-existing disc.
Looks more like defective or incompatible hardware.

7

It is ASUS DRW-24D5MT. I can’t manage to find any bug reports or something. Is there some issue with ASUS Disc Reader firmware with linux ?

8

It does not look like anything special. Is this “cat /dev/sr0” command giving “no medium” output or does it trigger additional lines in the log? Does it happen to be a dual boot system and gives windows similar problems?
