Is this during the installation process, or after you have installed Ubuntu?

After I have installed... I reformated both hard drives during the install.

Can you post the contents of your /etc/fstab file, and the output from the `mount` command here?


RattleHead (eaton72) said : #4

How do I get that for you?, remember Im a newb ;)

Bryce Harrington (bryce) said : #5

Oh, sorry:

Open up a Terminal window and type the following:

$ mount

$ cat /etc/fstab

Then copy and paste everything that was printed out, here.

No problem here you go

Okay, in this output, there are references to hard drive A ("hda") but none to a second hard drive ("hdb").

Go to Administration -> Disks, and see if it shows both of your hard drives in the Storage list. Click on them to see if one is named "/dev/hdb". If so, then click on the Partitions tab. Check to make sure the partition(s) are marked 'Active', and if not, try changing it to active.

You will also want to check the 'Access Path' settings for the partitions.

I dont have the option for disc under administration but I checked the device menu and it looks the same as the primary drive as far as I can see

Bryce Harrington (bryce) said : #9

The screenshot isn't coming through.

Can you describe in more detail what you're seeing? Also, do you see a secondary drive in the device menu? What is its 'Access Path' setting?

linux.sysfs_path_device strlist /sys/block/hdb

does this help???

Brian Murray (brian-murray) said : #11

Please add the output of your kernel messages via the command 'dmesg' in a terminal. These will help us determine whether or not your secondary hard drive was detected. Thanks in advance.
