  1. hmm, interesting: VirtualBox does 'see' single USB drives and can mount them as shared folders, but the new RAID box with two drives in a JBOD configuration seems to be 'invisible' to it - it's not there as a USB device, and I can navigate to one drive to mount as shared folder, but then it appears empty. #

    1. @mk "shared folder" sounds a bit strange wrt a usb device. Have you installed VirtualBox ExtensionPack for usb2.0 support?

      1. @mcscx2 welll 'shared folder' is what you use to mount a drive OR folder from the host system - it doesn't matter (it seems) whether that is a USB device or not - but you can *also* access USB devices directly - though not the same device at the same time, and better not while it's busy (as I just found out :-(). Still working on a possible workarund for the JBOD box. I have not installed an USB extension pack but it seems to be already supported anyway. Or maybe I did it when I first installed VB (and it's not specifically needed for a Linux Guest).

        1. @mk maybe the "shared folder" is a new feature for usb devices already mounted by the host system. Actually usb storage should be treated as a device, not as a filesystem. I'm not experienced with Linux as a guest system, though.

          1. @mcscx2 well, it supports both, and the interface is quite different. Remember that a USB device can have multiple partitions which could be mounted as "shared folders". First time Linux guest for me, too - so necessarily lots of things are new. Got the Extension Pack installed! I'm trying to get a stable VM with all drives accessible (or as much as possible), and make anotehr snapshot; then go for the real aim: install DarkTable.

          2. @mcscx2 so, let's see what difference (if any) the Extension Pack makes!

            1. @mk just looked up DarkTable: interesting!

              1. @mcscx2 I've used two programs mainly on the laptop during my SE Europe trip: LightZone and DarkTable. Both are awesome programs but use a rather different approach - for some situations one is better, for others the other; also tools for the same functionality can be very different: it takes quoite a while before you get familiar with their 'idioms'. But I want both on the desktop, too - and most of all DarkTable since I ended up using that the most.

            2. @mk btw. I usually don't connect usb drives directly to a guest machine. My method: I create a vmdk file "sdX.vmdk"for /dev/sdX and connect the host's /dev/sdX device to the guest machine. It will look like a sata device to the guest. Faster+more reliable

              1. @mcscx2 that sounds interesting, I'll have to look into that. Most 'visible' USB devices mount (and a File Manager window pops up) but there are three that don't - I suspect one of them is the new RAID/JBOD box, and two others may just be hubs. But I see no difference in behavior with or without the Extension Pack... I think the USB method is good for flash drives that are plugged in only every now and then, and your method woukd be good for 'permanent' external USB drives.

                1. @mk If /dev/sdb is your jbod device, as seen from the host, then "VBoxManage internalcommands createrawvmdk -filename /root/sdb-jbod-box.vmdk -rawdisk /dev/sdb" will create the vmdk file. As always, the jbod device mustn't be mounted by the host

                  1. @mcscx2 thanks, I'll try that #!

      2. @mcscx2 oh, under Settings there is under USB a checkbox for 'USB controiller' and below that one for 'USB 2.0 (EHCI) controller which the tooltip says is for USB 2.0 support. I did not have it checked (but it handled my little Flash drive just fine anyway). So, I can try enabling that; and I can also note that there isn't a checkbox for anything USB 3.0...
