VirtualBox: Boot from USB

Add a Comment[Author: Category: VirtualBox ]

Hi,

Virtualbox allows to boot from USB. But this feature isn’t exposed to the GUI.

Lets start. First of all determine the physical disk. Open Powershell and query the disks by WMI

PS D:\> Get-WmiObject -Query "Select * from Win32_DiskDrive"

Partitions : 3
DeviceID   : \\.\PHYSICALDRIVE0
Model      : Samsung SSD 850 PRO 512G
Size       : 512105932800
Caption    : Samsung SSD 850 PRO 512G

Partitions : 1
DeviceID   : \\.\PHYSICALDRIVE2
Model      : Generic USB CF Reader USB Device
Size       : 4030387200

I have no KNX USB Interface for testing and therefore Bastian Herzog did that part and supports me to improve the script. Very special thanks to him. Together we have get this started.

Linux: Switch a idle hard disk into standby mode

2 Comments[Author: Category: Linux ]

Hi,

I have running a debian based multimedia server. The operating systems is installed on a compact flash card (/dev/sda), the data resides on a external USB SATA harddisk (/dev/sdb).
The (Server 🙂 ) Hardware is a Fujitsu Futro A240 ThinClient, with a power consumption of only 7W. I’m using the server for about 2 hours each day, therefore I looked for a method to save power and switch the USB disk to standby mode when its idle for while.

Check first if your hard disk supports the standby mode.  Ensure that the disk is idle, otherwise the disk is immediately active again.

Switch to Standby mode

root@debdev:~# hdparm -y /dev/sdb

But there is a workaround:-) Use the Plop Boot Manager. Download the latest ZIP File and extract the plpbt.iso file. This contains a CD image which starts plop boot manager. Connect the iso file as  a virtual CDROM to your virtual machine.
