Kubuntu 11.04, Fat32 access denied.

Bhakta Neal · 08-20-2011, 09:32 AM

Hi, friends,

I am using a Toshiba P7500 series laptop, i3 dual core, 6GB ram,

This is a brand new machine. I was trying to recreate the conditions specified in a previous thread of mine, located here:
http://www.linuxquestions.org/questi...itions-881489/

I have followed the steps as good as I could. The main difference that I think is causing me problems is the fact that I am now trying to do this (explained in that thread) with a Fat32 instead of the ext3.

I THINK I know where my mistake is, but not sure how to fix. In the fstab, and in the mkdir, I am not sure how to address the fat filesystem.

To recap my intentions:
I want my FAT32 partition to mount automatically, and have a presence in my /home. In my other machine, where this is working flawlessly, my "file storage" partition (named "DATA" in the other thread, and was an ext3), this partition looks and behaves just like any other subdirectory under /home.

Right now, with my attempt at a setup, and with my error, the partition is not accessible anymore.

I hope all this makes sense. Sorry if it is confusing.
Please take me step-by-step so i can understand the process much better.

Thank you
Neal

Hi Neal,

How are you doing buddy? Let's see if we can fix this thing that's giving you headaches. First of all, sorry for the late reply, I was out whole day yesterday.

Can you post output of :

Code:

cat /etc/fstab

and

Code:

mount

Kind regards,

Eric

Im doing great bud, just so anxious to get things done before the trip, so this mistake I made is not helping!
Eventually you will see that I tried to follow your instructions in that old thread, but I hit the wall because Im working with FAT32 on this one, and I remember vaguely that fat32 has a little bit different process?

Bhakta Neal · 08-21-2011, 07:36 AM

In post #3, the last line

Quote:

/dev/sda8 /mnt/data fat32 auto,user,rw 1 2

was entered to fstab by me, attempting to follow instructions!

EricTRA · 08-21-2011, 02:29 PM

Hi buddy,

Sorry for the late response, I spend a day at the beach with 96 degrees F. Change fat32 to vfat and try again.

Kind regards,

Eric

Bhakta Neal · 08-21-2011, 02:59 PM

THANKS!
Workin on that now

Bhakta Neal · 08-21-2011, 03:16 PM

Great that allows me access now.

However, there is a slight bug:

In my Dolphin, in the "Places" margin, there is the drive "Fatass32" (which I named with gparted during initial setup), which is my FAT32 prtition. This is correct behavior.

Also, under my /home directory, there is a "FatAss32" directory.

When I click to open .......
Wait, I just noticed something important.

My partition is named Fatass32, and my file manager directory is FatAss32. They have different names, which is probably why when I try to open FatAss32, I get a new, blank empty folder, instead of seeing the files already in place on Fatass32.

I am sure I made the mistake during the mkdir instruction. How can I fix it?

EricTRA · 08-22-2011, 12:30 AM

Hi Neal,

Most likely you created two directories. Delete the one you don't use/which doesn't contain data, check that your mountpoint in /etc/fstab refers to the correct one and run:

Code:

sudo mount -a

if you changed something in /etc/fstab.

Kind regards,

Eric

Hi Eric, hope you had a nice weekend! Sounds like it!

Hope this part looks right:

Hi buddy,

Yeah, I had a very nice weekend. Hope you did too. Your /etc/fstab looks OK to me. But you mount your vfat to /mnt/data. Does that mean you created a symbolic link in your home directory? I'm a bit confused with your explanation of the two directories Fat... Did you create two directories and a symbolic link as I suspect or did you mount your partition under one of those directories?

Kind regards,

Eric

Bhakta Neal · 08-22-2011, 01:21 AM

Well, my intention was to make the Fatass32 (FAT32 file sys) drive behave like the ext3 that you helped me set up in the old thread:
http://www.linuxquestions.org/questi...itions-881489/

The behavior:
To access the partition, I simply navigated via gui to /home/DATA. /DATA was a folder under /home, as if it were simply just a subdirectory. Therefore, my intuition tells me this is a symbolic link. Is that correct? I did not need to navigate to /mnt or /media.

You know, I can still turn on that machine, and view the settings, then replicate...

In my GUI I have 2 different folders: Fatass32 and FatAss32.
Fatass32 currently opens the FAT32 partition, while FatAss32 opens a blank folder (and should be erased, it is not needed.)

The other machine is running now, so let me know if an fstab or other would help

EricTRA · 08-22-2011, 01:24 AM

Hi,

According to your fstab you're mounting /dev/sda8 on /mnt/data. So I assume you made a symbolic link. You can confirm that with the output of

Code:

ls -l

in your home directory. Better practice would be to mount the disk directly on /home/Fatass32 if that's the directory you want to use in combination with your FAT32 partition.

Kind regards,

Eric
