External hard drive fstab issues

Hi all,

I just bought a Toshiba 1tb external drive, and I have it mounting correctly with no problems.  My issue is that everytime I mount it, the Toshiba virtual cd (which is meant to install Windows software) mounts along with it, which is really annoying.  I have tried to add an entry to /etc/fstab to stop the virtual cd from automounting, but I don't have the syntax right.  Could anyone tell me what I am doing wrong?

My /etc/fstab:

#
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0

/dev/sdb         /media/Toshiba-1TB   auto     user,auto,rw
/dev/cdrom        /media/Virtual\ CD  auto    noauto,nouser

#/dev/cdrom             /media/cd   auto    ro,user,noauto,unhide   0      0
#/dev/dvd               /media/dvd  auto    ro,user,noauto,unhide   0      0
#/dev/fd0               /media/fl   auto    user,noauto             0      0

UUID=68977fe1-5b26-4ab7-9939-0d97bcba31d8 /home ext4 defaults 0 1
UUID=c0fff82b-b45c-4fe0-9dfb-f45e6b2f403d / ext4 defaults 0 1

/dev/sdb is the external drive, and /media/Virtual\ CD is what I don't want to mount.

Perhaps vfat in place of auto?

Re: External hard drive fstab issues

Thanks for the response.  Tried that and it still mounts on boot-up.  Under the properties of the CD, the file system type is listed as "iso9660 (joliet extension)".  I tried replacing auto with iso9660, and that didn't work either.

Re: External hard drive fstab issues

This looks like the same behaviour as my USB key with U3. I think this might work:
When you plug in the drive, run dmesg and see what drives it assigns for the drive and virtual cdrom. In my case, it is /dev/sdc1 for the key, and /dev/sr1 for the cdrom.

Edit /etc/fstab with these values (using my examples here):

/dev/sdc1         /media/Toshiba-1TB   auto     user,auto,rw
/dev/sr1       /media/Virtual\ CD  auto    noauto,nouser

Then see if it is still automounting both. If it is, you could (maybe inelegantly) work around it by adding something like 'umount /media/Virtual\ CD' in your /etc/rc.local.

Okay, I ran dmesg, but I'm not sure which drive the virtual cd was assigned to.

Dmesg output:

Would it be at /dev/sr1?

EDIT: It appears that it was indeed mounting at /dev/sr1.  Thank you so much.
