160 gb hard disk showing 120 gb only...

[vagrantjoe]

I'm using Meerkat in my Inspiron 1525... 160gb hard disk...
But nautilus is showing that the disk capacity is 120gb... So should I update my BIOS? If yes, how do I do it? I tried searching the net and my brain's dead... Kindly help me fellow ubuntuans...

[dabl]

What is the output of
sudo fdisk -lu and
sudo df -h?

[vagrantjoe]

Thanks for showing interest mate...

[vagrantjoe]

is everything ok with the pc?

[dabl]

Is swap active? Show the output of


sudo mount

If it is, that's probably where the rest of your "missing" space is. Remember, the drive OEM's "160G" is 160 billion bytes. It is not (1024 x 1024 x 1024 x 160) bytes. Linux (and other OS's) measure in Kbytes, Mbytes, and Gbytes, which are multiples of Kilobytes which are 1024 bytes each.

I think your drive is fine.

so is swap active? and what is swap? don't bother to explain if it's too complicated... I wish I knew linux well enough to contribute like you and other guys here do... I'm only a month old linux ubuntu baby... lol!!!

[dabl]

I don't see swap mounted, but I do see an encryped fs. I wonder how much disk space that hides?

Try, in the terminal, issuing
sudo swapon

let's see if it throws an error.

[vagrantjoe]

Usage:
swapon -a [-e] [-v] [-f] enable all swaps from /etc/fstab
swapon [-p priority] [-v] [-f] <special> enable given swap
swapon -s display swap usage summary
swapon -h display help
swapon -V display version

The <special> parameter:
{-L label | LABEL=label} LABEL of device to be used
{-U uuid | UUID=uuid} UUID of device to be used
<device> name of device to be used
<file> name of file to be used




I did create a private folder using the below steps


Setting-up the encrypted folder is simple. First, if you haven’t already, update your system software as described at the beginning of this chapter. Then open a terminal window (Applications Accessories Terminal) and type the following commands:

sudo apt‐get install ecryptfs‐utils
ecryptfs‐setup‐private

You’ll need to type your login password when prompted after typing the second of the commands. You’ll also be invited to create a mount passphrase. This can be anything from a few words to a sentence, and can include numbers and symbols such as punctuation marks. Ensure you remember what you type because you might need it at a future date 124 : Securing the System
to manually unlock the filestore! Alternatively, you can simply hit Enter to have a passphrase generated automatically, but you should print out the passphrase and store it in a secure location. Once the commands have completed, log out and back in again. When the desktop appears, you’ll find you have a new /private folder within your /home folder. As mentioned, this can be used just like a standard folder—files and folders can be stored there, and you will see no sign that the contents of the folder are in fact encrypted.

Let's see the output of
cat /etc/fstab

and also try to turn swap on again with the -f flag:


sudo swapon -f

[vagrantjoe]

joseph@joseph-Inspiron-1525:~$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>

and....

maybe you have already tried this:
boot from a gparted or pmagic cd and look what kind of partitions are shown.

there might be a hidden system partition?

[dabl]

# swap was on /dev/sda5 during installation
UUID=bff9ddbc-070f-4222-889c-a1a52b5e57ff none swap sw 0 0



So you do (or did) have a swap partition defined in /etc/fstab.

I'd like to see the output of
sudo blkid

I'm wondering if somehow the UUID of that partition has been subsequently changed.

[psusi]

It is because of the definition of a gigabyte. The computer industry long ago defined a kilobyte to be 1024 bytes, a megabyte to be 1024 kb, and a gigabyte to be 1024 mb. Because of this you actually have a 149 GB drive, but hard drive manufacturers decided to define a gb as 1,000,000,000 bytes and mislabel their drives to be larger than they are.

On top of that the filesystem has a bit of overhead, and on top of that, ext[234] reserves 5% of the space for root by default.

so psusi what you're saying that my pc is fine?

It looks to me like your pc is just fine.

[psusi]

so psusi what you're saying that my pc is fine?

Yes.

thanks guys... thanks a lot...
