DVD RAM particular disk is not mounting while another type is

jshort1 · 03-03-2008, 01:11 AM

I have two types of DVD RAM media. One type mounts and the other doesn't.
The successful media which mounts is Verbatim DVD-RAM 9.4 GB, up to 3X speed rewritable Type 4. The unsuccessful media is Maxell 9.4 GB - Type 4, up to 3X speed rewritable. I've tried to mount four different Maxell disks so I don't think it is a defective disk. Is it possible the disk is just incompatible with the drive?

I tried checking with the LG site but they seemed to only have information for Windows OS.

The DVD drive is an LG GSA-H10N.

The Linux version information is
Linux version 2.6.12-1.1378_FC3
gcc version 3.4.4 20050721 (Red Hat 3.4.4-2)

command:
mount -t vfat /dev/hdd /media/cdrecorder4

Any ideas why one disk type mounts and not another type?

The format of the media is not vfat it is UDF, try somethig like;

mount -t auto /dev/hdd /media/cdrecorder4

If the device is in /etc/fstab then make sure the entry looks something like;

Code:

/dev/hdd               /media/cdrecorder4             auto    noauto,users,rw 0 0

The you can just use for example: mount /media/cdrecorder4

Thanks for the reply.

Here's the command and the error resulting:

[root@cstt ~]# mount -t auto /dev/hdd /media/cdrecorder4
mount: you must specify the filesystem type
[root@cstt ~]# dmesg |tail

If the correct /etc/fstab entry for the DVD drive is in place then one only needs to type;

mount /media/cdrecorder4

Or if you insist one need to be exact, in the case of the UDF DVD;

mount -t udf /dev/hdd /media/cdrecorder4

Please review the man page for mount; man mount

Here's a snippet;

Code:

       -t vfstype
              The  argument following the -t is used to indicate the file sys-
              tem type.  The file system types which are  currently  supported
              include:  adfs,  affs,  autofs,  cifs,  coda,  coherent, cramfs,
              debugfs, devpts, efs, ext, ext2, ext3, hfs, hpfs, iso9660,  jfs,
              minix,  msdos,  ncpfs, nfs, nfs4, ntfs, proc, qnx4, ramfs, reis-
              erfs, romfs, smbfs, sysv, tmpfs, udf, ufs, umsdos, usbfs,  vfat,
              xenix,  xfs,  xiafs.   Note  that  coherent,  sysv and xenix are
              equivalent and that xenix and coherent will be removed  at  some
              point  in  the  future  -- use sysv instead. Since kernel version
              2.1.21 the types ext and xiafs do not  exist  anymore.  Earlier,
              usbfs was known as usbdevfs.
