One of my hard drives won't "mount"

Please give us some more details of your storage devices

What filesystems are on that devices...? (NTFS or FAT or FAT32)
Are that filesystems checked, are they in no error state...?

Thank you

You probably have a ntfs partition on the system drive that windows uses.

Use gparted to find the name of that partition and mount it by editing /etc/fstab
I would write more to explain how to do this, but I gotta run. I hope I pointed you in the right direction, and just ask if you need additional help.

Considering I have no clue what gparted is... I'm definitely gonna need additional help.

They are ntfs drives... the last action I performed on the drives before converting to UBUNTU was converting the storage drive from a basic drive to a dynamic one. I left the drive in question as a basic drive. I don't know if it helps but I found it coincidental that the basic drive was the one that wasn' being read.

You will want to add an entry to you fstab which uses nfts-3g driver. Fstab is located at /etc/fstab. So to edit it you would type

sudo gedit /etc/fstab

For example. I added this entry to add my ntfs partition on my first harddrive.

/dev/sda5 /home/sid/Drives/D ntfs-3g defaults,umask=000,users 0 0

Now many people would say those permissions (the umask=XXX) are a security threat because it allows everything, but it also comes with the advantages always allowing read/write/execute privileges.

the fist bit has to be the drive and partition. For example you may see a sda5 partition. sda means its my first harddrive and 5 means its the 5th partition. Or perhaps you have a second harddrive, then you would see sdb 1, sbd2, sbd3 and so on depending on how many partitions you have. You can use gparted to see what your harddrive and partition are labeled as. The next bit is the folder where I want to mount the drive to. I made a file in my /home/Drives folder named D and mounted my partition to that. Next comes the driver to use. Since its a ntfs drive, i am using the ntfs-3g driver. Umask is the permissions for the dive.
and To be perfectly honest I have no idea what users 0 0 is there for, but it was on my default entries so I added that as way.

Gparted is a program like partition magic. You can use it to edit your partitions on the drives, but for this purpose we only need to see the name of the partitions you want to mount. To run it, just type gparted in console.

Now just type sudo mount -a and it should mount your drive at the folder you specified.

I hope that wasnt too confusing :)

You can also try to use a simple tool to config the mount point of NTFS partition, first install it:

Please open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo apt-get update; sudo apt-get install ntfs-config

give your user password when requested, you don't see nothing when you type it, then press enter.

Then try to play with Applications->System tools->NTFS configuration tool

Hope this help

Marcobra, is that NTFS config tool a user friendly way to edit fstab?

Is a simple, very simple, tools to mount NTFS partition... (even in read and write mode)
