I have a real Ubuntu 12.10 installation being virtualized under a Windows 8 host, by using the VBoxManage.exe internalcommands createrawvmdk method.

I'm trying to mount an exFAT partition into the virtualized machine (which is the partition of shared work files), but even though I have fuse-exfat installed, and the partition is perfectly mountable while booting entirely into Ubuntu, I can't mount it while virtualizing it.

1- If I make a full vmdk image of the HDD, including all partitions, Ubuntu 12.10 "sees" the partition, and trying to mount it throws this error:


2- If I make a machine with only the linux partitions, + the exFAT partition. Again Ubuntu "sees" the partition and the result is:

Error: fsync failed


3- If I make a machine with only the linux partitions, and try to mount it, Ubuntu doesn't "see" the partition, and I get this error:


I've tried using the VirtualBox' "Shared Folders" functionality but even though I install the "Guest Additions", the system doesn't seem to recognize the shared folder:


Help? Thanks!

The linux install being virtualized is Ubuntu 12.10. Using exfat not capitalized works but still throws an error. Updated the question. – Alain Jacomet Forte Oct 21 '12 at 16:17
