[SOLVED] ASUS CD writer installation issues

Hi my friends,

I just plugged in a new ASUS DRW-24D5MT optical drive (internal SATA) and some strange behaviors happened.

  1. the BIOS sees the hardware
  2. Manjaro sees the device.
ale@ale-pc ~> sudo lshw -C disk
[sudo] password di ale: 
       description: DVD-RAM writer
       physical id: 0.1.0
       bus info: scsi@5:0.1.0
       logical name: /dev/cdrom
       logical name: /dev/sr0
       capabilities: audio cd-r cd-rw dvd dvd-r dvd-ram
       configuration: status=open
  1. Brasero does not see the drive.
  2. The file managers (neither Thunar, nor PCManFM) do not see the drive
  3. Differently from before, all the above listed partitions are not shown in the file manager except the ones specified in /etc/fstab (/, home and sdd3 that I mamually added to fstab).
  4. one tmp partition appeared, including files like “qipc_systemsem_MSMNotifier1982c3c75cbed4786bc185973fce6242a7b208b8” and folders like “systemd-private-82a33fd7e7894e43b078d400d1330c24-upower”
  5. gparted needs ages to scan the hard disks (before installing the Asus drive it was fast)
  6. PC slows down and/or freeze randomly when I try to access ti the filesystem
  7. this is the output of stat
ale@ale-pc ~> stat /dev/sr0
  File: /dev/sr0
  Dim.: 0         	Blocchi: 0          Blocco di IO: 4096   file speciale a blocchi

I googled a lot without success.
could someone help me please?

Don’t add the device to fstab - as it is a dynamic device - content depending on the media available.

Let udev handle the device …

Hi aarhus,
I did NOT added the device to fstab.

I just said that only the partition (I have 4 HDD and several partitions) sdd3 that I manually added to fstab is now visible.
The other ones were visible before I plugged in the optical device.

Maybe you need the package avfs - it contains drivers for various compressed filesystem among them iso9660.

I have no idea why the device should behave differently but one idea is media inserted - is it empty?

Try switching the media in the drive.

I installed avfs and rebooted but nothing has changed.
the behavior of the device with or without the media inside is the same…

Check your connection cables - also try detaching the device - verify that gpart scanning rate is back to normal.

If you can reproduce the scanning of devices good when cd device is disconnected - bad when connected.

My guess is either bad cables or bad device.

You are right!
I moved the device on the MB from SATA 5 to SATA 6 and everything run smoothly.

Thank you!
