trouble mounting a NTFS drive with Webmin

[petercli]

hello,
I have Raspbian Wheezy ver3.18 on a Raspberry PI, and I installed 'ntfs-3g'
I am trying to mount a NTFS USB drive using WebMin ( System / Disk and Network File System)
For Windows NT File System/ Disk, the list box shows "??? (Windows Fat16)" <-- is that correct?
When I click create, I get a error : Failed to save mount : The device file '/dev/mmcblk01' does not exist

Is this because I need a self-powered USB Disk drive ?

Thanks, Peter

Any usb-disk should pop up as "/dev/sda" and each partition as "/dev/sda1". It looks like you try to mount the boot partition on your SD-card and that won't work.

Boot the pi, run "dmesg", plug in the disk, run "dmesg" again and look at the new lines.

What kind of disk do you have ?

Hi Topguy,
I am a Linux newbie, but I want to learn.
My PI has a SD Drive with OS, and the USB Disk drive.
In the 'create mount' screen, in the Windows NT FileSystem , I choose 'Other device' , and then '/dev/sda1' , and it seemed to work! ( I am guessing that sda1 is my usb drive based on the result of running dmesg after plugging in the usb drive:

sda is a 2 terabyte (1.8TiB) drive with a single partition (sda1) on it.

Does it really need to be NTFS? If it is going to be permanently mounted on your Raspberry you WILL want to reformat that drive as ext4.

Ext4 gives a couple of instant benefits:
1. It runs faster because the driver is in the kernel not in user space
2. It works with the Linux owners, groups and permissions security model
