Troubles with mounting hard-drive. Cannot even mount or access in root.

eBopBob · 08-18-2004, 11:41 AM

Hi all.

I've a major problem. CDs will not mount. Neither media nor data CDs. I have to boot into Windows to access 'em. I've all things needed. I can't even access 'em when I log into root! I mount it with

mount /dev/dvd
or
mount /dev/cdrom
or
mount /dev/hdc

Nothing works. I then do mount in Konsole, and it says that my DVD-ROM has been mounted, yet I'm unable to access my CDs. I can listed to my music CDs through CDPlayer or KSCD or something like that; but I cannot access them in /media/dvd nor can I access my data CDs there. Kinda driving me nuts. I've searched and nothing I've tried works.

Any help please? Must I edit something?

When I do mount in Konsole, I get:

Quote:

/dev/hda3 on / type reiserfs (rw,acl,user_xattr)
proc on /proc type proc (rw)
tmpfs on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
/dev/hda1 on /windows/C type vfat (rw,noexec,nosuid,nodev,gid=100,umask=0002,iocharset=utf8)
/dev/fd0 on /media/floppy type subfs (rw,nosuid,nodev,sync,fs=floppyfss,procuid)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/hdc on /media/dvd type subfs (ro,nosuid,nodev,fs=cdfss,procuid,iocharset=utf8)

So my DVD drive has been mounted; but I just can't access it. It says "Could not enter folder /media/dvd" - and it doesn't say why. It says ownership is root and user is root; but even when logged in as root I cannot enter it, nor modify its properties. Makes no sense to me at all. I check in the /var/log/messages and got this:

As you can see, I'm stumped.

Any help is MUCH appreciated.

ebopbob; back to basics, read those printouts (even if hardcopied) very carefully with explicite attention to those errors (clues where what needs done). u may need to redo the permissions to execute commands. (notice rw on konsule mnt) that is read/write. what happened to rwx those are the permissions. so redo in correct sequence then things go in working order.

I guess suse has some issues with automount, indeed. I've seen this here, and people have frequently reported problems here at LQ.

Try to mount'em as if no automount were present. Just su to root, then do "mount /dev/hdc /media/dvd" with a data cd inside.
Post here the output of the console.

Ok.... I'm new here, so bare with me!

The permissions for the DVD when doing mount at Konsole say ro. That means Read Only I presume. I right clicked on the DVD icon on my desktop, went to permissions, and it says Owner = Read Only, while Group and Others were forbidden. Should I change it so they are ALL Read Only, or what?
I'm guessing the error is to do with permissions. What else could it be?
Also the problem is, I've no idea what the errors in /var/log/messages mean.

And STILL it says the same old same old. I cannot enter /media/dvd
When I do mount in Konsole, I get:

So, what should I do???
