You can connect multiple USB device to the LinkStation via a USB hub. However, you must modify 2 files in order to share more than 1 USB disk. The following information details connecting 2 USB disks but can easily be modified to cover any number of disks.

3.) Then reboot the Linkstation for the new settings to take effect. The additional USB disk(s) won't appear in the web interface.

+
-
shutdown -r now

+
-
'''mindbender-21.5.06:''' this is true at the moment if you use the 2.6-kernel. if you use the stock-kernel, then you will see the second usb-hdd over the webinterface and you can even format it as normal. in the status screen you will see all the information also accordingly.

-
 
+
-
4.) It's worth pointing out that I had already formatted the additional USB disk on another machine before doing any of this. This should all work for vfat, ext2 or ext3 file systems.

USB Hard Drive
Image:Bar.png
The LinkStation's USB port may not provide enough current for some USB-powered hard drives.


You can connect multiple USB device to the LinkStation via a USB hub. However, you must modify 2 files in order to share more than 1 USB disk. The following information details connecting 2 USB disks but can easily be modified to cover any number of disks.

1.) Open the file in a text editor and adjust it to the following: 

vi /etc/murasaki/bin/mount_sd.sh



#!/bin/sh

BOOTCHECK=0
MNT_DIR1=/mnt2/usbdisk1
MNT_DIR2=/mnt2/usbdisk2
LOCK1=/var/lock/mount_sd1
LOCK2=/var/lock/mount_sd2
MOUNT_SD1=0
MOUNT_SD2=0

### check initial devices
if [ $# -eq 2] ; then
BOOTCHECK=1
fi

### parse usb device info
/usr/bin/parse_usbscsi > /dev/null 2>
