second hard disk partitioning

Asked by sandra.bodkin

I have two hard disks on my computer. The first one ,C: has 10 gig and I installed Ubuntu on this one. Now I need the second one E: for more storage space (documents, music , images). The partition manager tells me that this disk space is unallocated. My question is: Do I have to partition this disk before mounting it. And if so, how do I do this? Thanks.

No, you don't have to partition the disk to mount an existing partition.

First, let's see what your partition tables look like. Then, I will need to see if the "E:" partition is already mounted somewhere. Finally, we should make sure that the partition is not already referenced in your fstab file.

From a terminal window ("Applications" -> "Accessories" -> "Terminal"), type the following commands and send me the output:

    sudo fdisk -l
    mount
    cat /etc/fstab

Hi Sébastien! Thanks for answering. Here is what I get in terminal:

Hello naufal: Yes, that's what I thought, but I wasn't sure. I looked in partition and it said the second disk was unallocated, so I assumed it wasn't formatted for linux. Thanks, I'll try that and I'll be careful. Thanks for answering my question.
