fdisk -l permission denied

[foxint]

Sir...
the journey continues....

Each time I follow a step toward networking I get stopped:

pi@raspberrypi:~ $ fdisk -l

You are trying to do something that is restricted to root level access, so you'll need to tell the system you are serious by putting a sudo in front of the command and then typing your password:

sudo fdisk -l

Disk /dev/ram0:

There are a lot of ram drives in there messing with things, so filter them out with grep:

sudo fdisk -l | grep -v -e ram -e size -e Units

This is brute force matching and removing the lines with "ram" or "size" or "Units" that are part of the ram drive output and not displaying them leaving all the drives that are not ram drives and then you should see what you want. Usually the /dev/mmcblk stuff are sdcards and the /dev/sda and /dev/sdb etc. are usb flash drives or harddrives that are usb.

Hi
Thank you

Not sure what you told me....but I did the copy and paste and it was a lot clearer...not sure what all the stuff is... all I have is a SD card and a HHD attached....mouse keyboard...

I tried to mount the drive....why does it not work like the instructions????

pi@raspberrypi:~ $ mount -t auto /dev/sda1 /media/suppliers
mount: only root can use "--types" option
pi@raspberrypi:~ $

I followed some guys instructions and this is what happens????
Confused and upset.....

It's nothing clever at all but save it because you can continue to use it whenever you need to use fdisk.

Because either the instructions are wrong or for some other version or the writer is making assumptions.

pi@raspberrypi:~ $ mount -t auto /dev/sda1 /media/suppliers
mount: only root can use "--types" option
pi@raspberrypi:~ $

You need to put sudo in front of the mount command. The writer is assuming that you know that, apparently. Or, perhaps, he's using the # prompt which doesn't need the sudo. Does the tutorial have a # prompt or a $ prompt? Watch out for this, write it down in your notes.

[foxint]

Sir
totally confused

thsi is what I did:

pi@raspberrypi:/ $ sudo mount -t auto /dev/sda1/media/suppliers
mount: can't find /dev/sda1/media/suppliers in /etc/fstab
pi@raspberrypi:/ $

[stderr]

pi@raspberrypi:/ $ sudo mount -t auto /dev/sda1/media/suppliers
mount: can't find /dev/sda1/media/suppliers in /etc/fstab

It really is sudo mount sourceDevice destinationDirectory in this format so it would seem like you didn't put a space there:

sudo mount -t auto /dev/sda1 /media/suppliers

Notice that there will need to be a directory called /media/suppliers which won't exist if you didn't make it. So, before doing the above, do this:

sudo mkdir -p /media/suppliers

[foxint]

Sir
Thank you...I really cannot see the spaces or the difference...

But I have copied and pasted.....

pi@raspberrypi:/ $ sudo mkdir -p /media/suppliers
pi@raspberrypi:/ $ sudo mount -t auto /dev/sda1 /media/suppliers
Mount is denied because the NTFS volume is already exclusively opened.
The volume may be already mounted, or another software may use it which
could be identified for example by the help of the 'fuser' command.

cry:

Does this mean I have it or not??

I think that it mounted on its own. If you are using the GUI and you open up its file manager or maybe if you just have it installed, the default is to open it up, I think mounted in /media under some directory. You should look there, it's probably already good to go. (Remember that I don't know what you actual situation is, I'm just responding to your comments, you might not need to use mount at all)

Sir
Totally confused.....
I have used Window Explorer and the Pi is empty.....

I ahve tried to unmount...but all of the commands on the internet are not valid...

So I want to try again....nothing I do will allow me to unmount...if it is mounted... I tried to delete the directory....but no permission... I am a bit annoyed with permissions....it is only me....

Anyone can help???

[foxint]

Hi Guys
I want a NAS....that is all I want...everything I do is wrong:

this is what I did:
pi@raspberrypi:/ $ ls
bin home lost+found proc srv usr
boot jcameron-key.asc media root Suppliers var
dev jcameron-key.asc.1 mnt run sys webmin-setup.out
etc lib opt sbin tmp
pi@raspberrypi:/ $ sudo mount -t auto /dev/sda1/Suppliers
mount: can't find /dev/sda1/Suppliers in /etc/fstab
pi@raspberrypi:/ $ ls
bin home lost+found proc srv usr
boot jcameron-key.asc media root Suppliers var
dev jcameron-key.asc.1 mnt run sys webmin-setup.out
etc lib opt sbin tmp
pi@raspberrypi:/ $

I am totally confused.....I am trying to unmount the HDD ...orignally I tried to mount it and it said "mount denied"... but...when I view it from Webmin...I seem the HDD...now webmin says "Error - File not found"

The more I fix the more it become worse.....

Hi Guys

The whole pi stopped nothing would reboot.... I pulled the power and put it back...

Now it asks me to install the OS.....

Is there any way to make the simple....almost 14 days of HELL....this is the most irritating device in the world

Thanks for the help...but I will have to start this process all over again......
