DVD mount problem in RH 9.0

DVD mount problem in RH 9.0

Post by Celso & Daniela Suzu » Wed, 03 Dec 2003 21:42:01



Hi,
I have a DVD SonyDRU510 installed on a PC box with RedHat 9.0
installed.
And I couldnt mount the DVD driver with a DVD disc in it. If I put a
CD, it mounts OK.

I upgrade the dvdrecord-0.1.5-1ark.i586.rpm.
When I try to mount I get the message

mount: No medium found

Any ideia what is going on ?

TIA

Take the "kudzu" keyword out; it can cause problems.  Replace the
"udf,iso9660" filesystem type with "auto".  Data DVDs almost always use
the UDF filesystem.

This is fine.

Quote:> I upgrade the dvdrecord-0.1.5-1ark.i586.rpm.

That wouldn't do anything.  dvdrecord is only for recording DVD-R, and
it does nothing at all for mounting DVD-R*.


> mount: No medium found

What's dmesg say right after this happens?  What about if you force the
filesystem type like so?

(insert DVD-ROM)
mount -t udf /dev/cdrom /mnt/cdrom -o ro

...I have had no problems mounting DVD-R* media on my Gentoo system;
fstab line is like so:

/dev/cdroms/cdrom1   /mnt/dvd     auto       noauto,user   0 0

Hi,
Thank you for your reply!
Well, things didnt work as expected .....

I changed the /etc/fstab and reboot.
It still dont mount the DVD, CD mounts is fine.

I tried to mount and got the same error....

    mount: No medium found

dmesg results
    udf: registering filesystem
    cdrom: open failed.

/etc/fstab

    /dev/cdrom              /mnt/cdrom              auto    noauto,user     0 0

tried to mount directly

    mount: block device /dev/cdrom is write-protected, mounting read-only
    mount: No medium found

dmesg said three times with one command.

   cdrom: open failed.
   cdrom: open failed.
   cdrom: open failed.

Inserting a CD I have...

df result
    /dev/cdrom              258946    258946         0 100% /mnt/cdrom

dmesg result

    sr0: CDROM (ioctl) reports ILLEGAL REQUEST.
    ISO 9660 Extensions: Microsoft Joliet Level 3
    ISOFS: changing to secondary root

Any more ideias ?

TIA

Why did you reboot?  You didn't need to; mount reads /etc/fstab every
time mount is invoked.


> mount: No medium found

This means that the device thinks there's no medium there.  Is a DVD-ROM
(any movie DVD of the appropriate region for your geographical area will
do, I recommend "The Usual Suspects") in the drive?  Did you give the
drive time to read/calibrate itself for DVD?  It takes my DVD+RW about
20 seconds from when I insert a DVD-ROM for it to be able to mount; the
device has to figure out whether the medium is CD-ROM, CD-RW, DVD-ROM,
DVD+R, or DVD+RW, and adjust itself appropriately.

Quote:> dmesg results

Does "cdrecord -prcap dev=X,Y,Z" report that the device can read DVD-ROM
media?  Yeah, it should, but check anyway.

If it works for CDs but not DVDs, you might be having region code
problems.  Try with a region-free data DVD (if you can find one).

I think you're confusing a driver and *drive*.
The driver is the piece of software that allows the computer to
communicate with the drive.

The cable, maybe?

Bad secondary ide channel?
