missing hard drive.

[Newuser901]

I had a harddrive that I formated for extra space. It hasn't recognized or shown it in ages. I'm trying to figure out how to get it to show.

I had some data on it because I was going to use it to store all my large data like games. How do you get it to find it again and set it up properly as a second harddrive for storage purposes only?

I beleive it still shows up in lshw or some other command. But I have no idea what to do and mounting hard drives and stuff like this is very new to me.

Thanks for any help.

Please post the output of

sudo fdisk -lu

and await further help

Hi ,
it seems that your second hard drive (sdb) has a problem with partition table.
Run this command and post back the results

sudo parted -l

Please put the results inside [CODE] tags , by highlighting the text and click # symbol on top of message pane.
Thanks.

Hi ,
you can try to fix this problem .
2 suggestions:

1.)
With Fdisk tool.

Open a terminal and

sudo su 
fdisk /dev/sdb

n= create a new partition
1 = partition number
w= write changes to disk

click "m" for more options.

2.)
With e2fsck tool.
e2fsck tool its a check and repair tool for Linux filesystems.
Open a terminal and

sudo e2fsck  -f -v /dev/sdb

Post the results back here.

man e2fsck

for more.

Attention: Both ways pose risks to lose all your data .

Thanks

Hi ,
what result is that ? from what command ? sudo parted -l ?
Did you try the e2fsck tool ?
As you can see , you still have no file-system at /dev/sdb .
Thanks

I find GParted a much easier tool to use, try this tutorial after installing gparted:

sudo apt-get install gparted

good luck and cheers,

I ran the e2fsck command you gave me first but it make me hold enter down forever and seem to need me to answer thousands up on throusands of things and never stoppped. So I stopped the process and did fdisk.


I'll check out gparted.

after gparted.

Now it shows up in my home folder but i can't access it. It have the option to mount but it doesn't do anything when I click it. Is it bad there are two 250gig partitions seemingly on the same drive? It's only 250gigs to start.
