Description Stanislav Brabec 2007-08-20 13:14:49 UTC 
DVD-RAM should and CD-MRW (DVD-MRW, packet-write *RW) must be mounted noatime,nodiratime.

Mounting them with atime and diratime causes major slowdown (2x-8x depending on file sizes) and for CD-MRW it means medium wasting in a short time.

The same policy could be applicable for other devices with limited write count or slow write (flash memories, MTD).

For longer discussion see bug 119900.

Not a kernel issue, reassigning...
Comment 2 Danny Al-Gaaf 2008-02-22 15:44:21 UTC 
It's not a HAL issue, the desktop environment has simply to send the correct mount options while mount DVD-RAM or CD-MRW to HAL. HAL already allow noatime and nodiratime as mount options on linux file systems. 

I reassign this to the KDE ppl. They have to decide what to do for KDE and have, if needed to fix their code. Not sure if the same apply to GNOME.

Sorry, 10.3 is no longer supported. Please upgrade to 11.2. Closing.
Comment 4 Stanislav Brabec 2009-12-01 17:02:05 UTC 
It is still valid:

mkudffs --utf8 --media-type=dvdram --vid="TestUDF" /dev/sr1

Then eject and re-insert and run mount:

/dev/sr1 on /media/TestUDF type udf (rw,nosuid,nodev,uhelper=devkit,uid=10027,gid=100,iocharset=utf8,umask=0077)

As you can see, the device is still not mounted with noatime.

Thanks to the new kernel default, now it should cause slowdown only once daily.

CD-MRW medium has a chance to live for a month or so before it reaches permitted number of rewrites.

Hello, is this still a problem in KDE 4.3.5 or later?
Thank you

No response, closing...
Comment 7 Stanislav Brabec 2010-06-30 14:17:11 UTC 
Just installed openSUSE 11.3 RC1.

KDE: Device is mounted with default mount options. noatime is missing

GNOME: Mounting of removable media is completely broken.

Any update?
Comment 9 Stanislav Brabec 2010-11-24 15:21:29 UTC 
Re-tested on 11.3 final:

GNOME: Mounting of UDF formatted DVD-RAM is broken. Nothing happens.

I plan to restest it on Factory/11.4 soon.

@Standa: please reopen on TW if still an issue, preferably fix it yourself as this was open for 10 years.
