Thread: USB external storage partition

In the couple years I have been on Linux I have collected and categorized a huge amt data
that has me in a rather comprising position given my 40GB HD
I installed a 160 GB USB external projecting movement to same but I need the command line procedure for mount, mnt. pt. ownership/permission, rw
For now I will do it with 1 partition which I made ext3 labeled data1
Please advise is as user friendly fashion as needed for 77 yr old comprehension.
Hey not a joke, merely a reality
Thank you so much

Hello give this a try:


Become root or use sudo:

Code:

Prompt>sudo -s

Plug your device into the system and identify the correct partition name.

Code:

Prompt>dmesg |grep -i 'USB device'

Or you can use this to identify.

Code:

Prompt>grep USB /var/log/messages

You should see something similar to this:

Code:

Aug  29 11:52:26 kernel: USB device sda1: 3903488 512-byte hdwr sectors (1999 MB)

Now we are going to Mount the partition to an existing mount point (directory).

Create the mount point. I think you already created /data1 as you mentioned.

Code:

Prompt>mkdir -p /mnt/data1

Now let's mount the drive on the new mount point. Remember if yours is not /dev/sda1 change it to what you received from the grep of /var/log/messages.

Code:

Prompt>mount -t vfat -o rw,users /dev/sda1 /mnt/usbdevice

Verify that are mount was successful with:

Code:

Prompt>mount

You should see something like this:

Code:

/dev/sda1 on /mnt/usbdevice type vfat (rw,noexec,nosuid,nodev)

To remove the USB drive you must unmount.

Code:

Prompt>umount /mnt/usbdevice

Permission should be Read And Writable as is. If not please Post the output of this command:

Code:

la -alh /mnt/usbdevice

If you have issues in any of the above steps. Do not hesitate to post the error or your question or concern.

Jay:
Wow is right, but not my age, but the most specific, user friendly, forum reply I have ever received. I should have been on this site several years ago.
That being said I would be home free had I actually created a mnt. point I guess rather then just taking for granted the label created in gparted would suffice.

debian:/home/allen# mkdir -p /mnt/data1
debian:/home/allen# mount -t vfat -o rw,users /dev/sda1 /mnt/usbdevice
mount: mount point /mnt/usbdevice does not exist

So if you would be so kind as to give me that code to create the mnt point I will be there.

FYI: Went to partition Editor and sda1 reads /media/data1

Finally when you have nothing better to do this URL is one I did for one of my grandsons who was attending Rice. He wanted grand-dad bragging rights
Thanks again

I assumed that your mount point was /mnt/data1. And you know what happens when you assume.

You make a A$$ out of U and Me

ass,u,me

HEHE



Run this and see what we get. I change the /mnt/usbdevice to /mnt/data1

Code:

Prompt>mount -t vfat -o rw,users /dev/sda1 /mnt/data1

However if you want the command to create the mount point. Here you go:

Code:

Prompt>mkdir -p /mnt/usbdevice

The flag -p is for:
-p, --parents
no error if existing, make parent directories as needed


Please let me know your results.


Jaysunn

You are truly a inspiration to me. Only if I had the experience on using windows 3.1 and others. You have found a great site here and I hope you continue to ask your questions here.

I take pride in learning from the questions that I try to answer. I have been using linux for a while now. And when you think you know everything is when you are in trouble.

Cause than you are unable to learn from asking questions.


Good Luck With this wonderful O/S we call LINUX.

Ok I will go back and start over
So /dev/sda1 is already mounted or busy??? partition editor mounted or two keys shows
partition File Sys Mount Point Label
/dev/sda1 ext3 /media/Data1 Data1
debian:/home/allen# mount -t vfat -o rw,users /dev/sda1 /mnt/data1
mount: /dev/sda1 already mounted or /mnt/data1 busy
mount: according to mtab, /dev/sda1 is mounted on /media/Data1
debian:/home/allen# mkdir -p /mnt/usbdevice
debian:/home/allen#

Just called myself creating a mount point
/mnt/usbdevice to /mnt/data1

debian:/home/allen# /mnt/usbdevice to /mnt/data1
bash: /mnt/usbdevice: is a directory

So is my mount point a directory? Its me Jay not you.
Do me a favor as time permits based on what I have related thus far if its enough
go through the drill sequentially one more time (again when you can) I realize every one is not retired

Let's try this. Remove the usb cable attached to the hard drive from the linux box. So disconnect it from the computer.

type this and give me the results:

Code:

Prompt>fdisk -l

Next connect the usb cable again to the linux box.

Type this in a command prompt as root and post back the results.

Code:

Prompt>fdisk -l

I want to verify the device name of your USB device.

So is my mount point a directory?

The mount point is where you want to mount the device on the system. It is a directory. So that's why created the directory /mnt/usbdevice.

As for time. Do not worry. As you get good at shell scripting and automation. You can automate yourself out of job. However I am off today. So I love a challenge.

The time lapse is due to my getting the info on terminal, but for whatever reason I cannot paste. Right click only shows back, reload, bookmark, show only this frame.
Will keep trying

For copying and pasting from a ubuntu terminal give these steps a try:

Linux: How To Copy and Paste From the Command Line


Try this as well:

With keyboard:

Code:

Copy: Ctrl+Shift+C
Paste: Ctrl+Shift+V

Hope this helps.
