I am using dual operating system. one is windowd and other is ubuntu.
There are 4 drives in my pc like c,d,e,f
in ubuntu how to move to these drives from terminal.i mean how to change the drive.
Help.

Er, you could start by trying that simply means type the word 'mount' at a terminal. Don't know how much you know so you'd get a terminal in the aplication menu should think.

The disk devices will have names like /dev/sda*, /dev/sdb*, etc.. Or it might be hda. sda is the first disk, sdb the second and so on.

If the disk you are after is not there this means it is not mounted.

To mount it do, say: When the drive partition is mounted you can navigate to it in the normal way.

will give a map of all the disks and partitions.

EDIT: Sorry I misread post as usual. You get to the drive from a terminal with $ cd /mountpoint - e.g. cd /mnt/sdb2 then $ ls will list what is available. Find the mountpoints with the mount command.

You need to find out how those drive are identified in Linux.

They will not be C: D: and so on. They are consider directories.

The drives themselves, if they are mounted, are mounted to the /dev directory. In turn they are linked to a drive name in either the /mnt or /media directories.

The information about them is in the file system table in a file usually in the /etc folder called /etc/fstab.

For instance, on this desktop computer that I am using right now, there are several hard drives. Here's the list (taken from my fstab).

When I boot the computer, I am by default in the drive identified as /.

If I want to chamge to drive 2 at the command line, I type

cd /media/drive2 or cd /media/drive2/[subdirectory]

(Actually, I use symbolic links, but I won't go into them here.) To go back to the main drive, I can type just cd.

It is possible that Linux does not yet know those drives are there or knows they are there but doesn't know what to do with them. If that's the case, you have to tell it they are there. Without knowing more about your setup, I can't be sure.

Here's a link about mounting and unmounting drives:

Here's a post I wrote up in another life about adding hard drives to a system:

It's nothing earthshaking, but it has lots of links to more information about the Linux file structure, the fstab, and other pages explaining this stuff far better than I can.

You don't. Linux doesn't have 'drives' like Windows does. The drives/partitions are under mount points, like "/tmp", "/home" etc.

And as before..you've only ever responded to requests for more information, or followed up, on ONE of your previous threads. You've never even said "thanks" to ANYONE for helping you, and don't answer any questions.
