Mount: wrong fs type, bad option, bad superblock missing codepage or other error

Hello,

I am running a CentOS vm on a Windows 7 host and I recently installed the latest version of guest additions (3.2.8) when I received the error:

Code:

#mount -t vboxsf ez sequence_data/
mount: wrong fs type, bad option, bad superblock on ez,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

when trying to mount an external hard drive to the guest. I have done this procedure many times with no errors but now for whatever reason I don't know what happened. Please, let me know if you have any suggestions on how to fix this!

Thank you very much!

Maybe a silly question but are you running VirtualBox 3.2.8 on the host? When you write "external drive" is that a VirtualBox shared folder that is attached to the VM? Have you tried not specifying the file system type?

Yes, I am running the version 3.2.8 on my Windows 7 guest. The external drive is set up for sharing under the shared folders tab in the guest's settings. As for specifying the file system type - I don't think that there's a way to do such a thing (at least I have not found it). Hopefully these answer your questions!

I should also mention that after trying to mount the hard disk I received another error message:

Code:

/sbin/mount.vboxsf file does not exist

or something very similar to that. After getting this message I tried to create a file named "mount.vboxsf" and it still didn't work. Hopefully this helps!

Your Guest Additions installation on the CentOS has crashed somehow. Try reinstalling it. If this does not help, try installing newer or older version.
