!!!Data transfer to external HDD using USB connection
{{category All of Data Analysis System(Servers and Terminals)}}

・The terminal workstations in the open-use rooms (e.g., sbws*, alws*)
are available for data transfer to external HDD using USB connection.
NFS volumes (/mfst*) are mounted on the terminal workstations as well.
If you want to deal with data on the local work area (/wam*, /wah* ) of
the interactive data analysis servers of anam* and anah*, you need to
retrieve the data from anam* and/or anah* via SCP (*1).
*1) You are not allowed to transfer data from anam* and/or anah* to
the terminal workstations since the network access control is
performed to the terminal workstations. You can access the data
from the terminal workstations to anam* and/or anah*.
e.g.,
alws05{hogehoge}: cd /media/Data_disk (*2)
alws05{hogehoge}: scp -r anah05:/wah05a/hogehoge .
*2) For the case of using a formatted USB device.
The way to format your USB device is described below.
・Please prepare a USB device that will be formatted. Any USB device
can be used irrespective of the condition of its initial format, since
you need to format it first on the terminal workstations.
・The following procedures are how to run data transfer to a USB device
under your user account.
# All the following steps can be done with your user account.
1. Log-in the terminal workstation with your user account, and start
GNOME by "startx" command.
2. Connect the USB device you prepared. There are four USB ports
on the front of the terminal workstation, two on the left are for
USB 3.0 and two on the right are for USB 2.0 devices.
3. If the USB device is mounted automatically, you need to unmount it.
$ umount /media/(Volume Name)
4. Select "Applications" --> "System Tools" --> "Disk Utility" in the
menu bar of the main GUI.
5. Select the USB device you connected on the "Strorage Devices" area
in the left hand side of the "Disk Utility" window.
6. Delete the initial partition by clicking "Delete Partition" on the
"Volumes" area in the right hand side of the "Disk Utility" window.
7. Click "Format Volume" on the "Volumes" area in the right hand side
of the "Disk Utility" window.
8. Consider the following two items, and then select "Format" on a newly
opened window.
Type: Choose one from FAT, Ext2, Ext3, and Ext4
(We recommend to use one of these filesystems)
Name: Specify any volume name (e.g., Data_disk)
9. Select "Format" again after a confirmation of "Are you sure you want
to format the volume?"
# It takes about 20 min to complete the format of 2TB HDD.
10. Mount the formatted USB device. You need to either remove &
reconnect it or select "Mount volume" on the "Volumes" area in the
right hand side of the "Disk Utility" window.
11. Now you have the mounted USB device that is found in /media/
(e.g., /media/Data_disk).
The disk has 700 permission, whose owner:group is
(your user account):adcusers (*3). Therefore, you are ready to
transfer data to the USB device under your user account.
*3) adcusers is the common group name for general users in the
data analysis system.
We note that you need to be root of your computer if you want to transfer
the data in the USB device to your computer.
