Windows 7 host, Ubuntu 9.10 guest. Windows D drive shared with share name of DRIVE_D, created sharepoint /media/shared/. Whether mount or /sbin/mount.vboxsf, everything I tried elicited the protocol error. Finally, I changed the share name from the default DRIVE_D to shared and it worked. Played around with changing the share name, eventually changing it back to the VirtualBox default DRIVE_D and it still worked. This would appear to be a VirtualBox bug. Solution: don't use the default share name. Nathanael Had the same problem. Windows 7 host, Ubuntu 9.10 guest. Windows D drive shared with share name of DRIVE_D, created sharepoint /media/shared/.

I’ve found this solution:

For example:

mount -t vboxsf vshare /home/paulsiu/vshare

The problem is when you tried this, you get the following error:

/sbin/mount.vboxsf: mounting failed with the error: Protocol error

If you look at syslog, you’ll see the following error:

Nov 8 19:28:09 wxbuilder kernel: vboxvfs: sf_glob_alloc: vboxCallMapFolder failed rc=-102
Nov 8 19:28:09 wxbuilder kernel: sf_read_super_aux err=-71

Apparently, you’ll only get this error if you use the default sharename. When you create a new shared folder, Virtualbox will ask where your shared directory is on the host. When you select the shared directory, the sharename will default to that directory. If I create a shared folder at “/home/paulsiu/vshare”, virtualbox will generate a sharename of “vshare”.

I too have used mount.vboxsf with some success. It looks as if mount -t vboxsf is its alias in more customary syntax. Thanks Andrius. I too have used mount.vboxsf with some success.
