I'm trying to insert a SD card into my laptop (it's got a side slot for one) and have it show up on the guest machine running in a virtual box.

Host: Windows 7 64 for x86 Guest: Ubuntu 64bit

I want to configure things such that when I insert the SDcard into my laptop and my virtual box session is running I want to be able to see the device show up in /dev/sdX on my virtual machine.

Anyone know a way to do that? None of the settings seem to deal with SD cards.

It was suggested I create a rawdisk with the VBoxManager.exe with elevated privlages, I attempted it, but it fails for other reasons:

C:>"Program Files\Oracle\VirtualBox\VBoxManage" internalcommands createrawvmdk -filename MySSDDisk.vmdk -rawdisk \.\PHYSICALDRIVE3
VBoxManage.exe: error: Failed to create the VirtualBox object!
VBoxManage.exe: error: Code CO_E_SERVER_EXEC_FAILURE (0x80080005) - Server execu tion failed (extended info not available)
VBoxManage.exe: error: Most likely, the VirtualBox COM server is not running or failed to start.

Aren't SD cards shown up as USB devices in VirtualBox? Is it necessary for you that it is always the same /dev/sdX? And finally did you consider using a shared folder? – Bertram Nudelbach Aug 5 '13 at 6:59

From the Windows host determine the physical drive

wmic diskdrive list > drives.txt
notepad drives.txt

Once you know your drive, you can attach it as a raw disk. Example below uses PhysicalDrive2. The following command must be done with elevated privileges:

VBoxManage internalcommands createrawvmdk -filename MySSDDisk.vmdk -rawdisk \\.\PhysicalDrive2

Attach the disk to the Virtual box and you should see the /dev/sd*x* when you start up Ubuntu

Got to give a +1 for the idea, but seems like it's not working for some reason. I'll have to dig into the failure unless you know why it's giving a server execution failure – Mike Aug 8 '13 at 16:00
Mike did you try also \\.\PhysicalDrive3 (no caps, and extra slash)? But you might be running into some other exotic thing. – Sentient Aug 8 '13 at 22:22
Yeah, slashes and/or caps don't seem to effect the end result at all – Mike Aug 12 '13 at 15:34
