Odd usb mount from HDD


Forum Supporter
I have, repeatedly, the symbol on the webif showing a USB device mounted when nothing is in the USB slots.
Investigating I found these results from mount and fdisk:

I think this anomaly was introduced when installing a new HDD, and having both attached for copying.
ISTR something in an earlier posting, but cannot think what to search on to find it.
I'd like to know how to remove the oddity.

Virtual-disk2 is the culprit. The latest version of NTFS-3G will install this as a dependency. It is to do with an update to allow NTFS disks with gpt partition tables to be used. The Humax SUI does not recognise when a gpt USB disk is plugged in so it will not open the USB menu. Virtual-disk2 gets around this by mounting a virtual disk as 'media/drive1'.
If you are not using USB disks with gpt you can remove the package from the command line: opkg remove virtual-disk2 --force-depends. If you reinstall NTFS-3G, or it is updated the virtual-disk2 package will be installed again too.

Thanks for the info - I do have ntfs-3G installed, and didn't realise that this would automatically have included virtual-disk2.
