Re: Hard drive information . . . but I don't entirely understand what I'm looking at

To clarify the situation, I would say disconnect the external USB drives -- they may be one source of confusion.

Then use oshunluvr's excellent blkid command:

Code:

blkid -c /dev/null -o list

and see what you have.

Re: Hard drive information . . . but I don't entirely understand what I'm looking at

Here's the output from oshunlvr's code:

device fs_type label mount point UUID
--------------------------------------------------------------------
/dev/sda1 /
/dev/sda5 /usr/local
/dev/sda6 /home
/dev/sdb1 /media/disk
/dev/sdb5 (not mounted)
/dev/sdb6 <swap>
/dev/sdb7 (not mounted)

So, am I right that the "missing" space is probably on (in?) sdb5 and sdb7, which I need to mount? If so, I think the syntax is "mount -t sbd5" but what should I specify as the directory?

You would have to make a mount point, for example

Code:

sudo mkdir -p /mnt/MYRANDOMSTUFF

Then you add a line in /etc/fstab to mount it, and you need to use the UUID, not the /dev/sdx confusion. So, you might write a line that looks like this:

Code:

UUID=82fffe8d-a8b1-49f7-afce-6ff01bc544bf   /mnt/MYRANDOMSTUFF    ext4    auto,users,rw,exec,noatime 0 2

what @dibl sead and hears some more....

that was with the USB drives unplugged right ?

onley the drives listed in fstab will be mounted at boot ......all others SHOULD be accessible from dolphin's places panel .

a comand line mount of a drive would be some thing like this.....first creating the DIR to mount to.

Code:

sudo mkdir /mnt/disk1 && sudo mount -t ext3 /dev/sdb5 /mnt/disk1

sudo mkdir makes the DIR .....&& goes to the next command ........mount -t is type in this exampel we used ext3 if the partition is somthing elce use that.
/dev/sdb5 is the partition to mount and /mnt/disk1 the DIR(place) we made to mount it to.

Re: Hard drive information . . . but I don't entirely understand what I'm looking at

The old /dev/sdx device numbering basically ran out of gas with the advent of USB hard drives. They don't connect directly to the hard drive controller, and they cannot be assumed to be present at boot time, when the hard drives are enumerated, so /dev/sdx does not work reliably with USB drives. That's why all modern Linux distributions have moved to default UUID drive identification.

Re: Hard drive information . . . but I don't entirely understand what I'm looking at

Based on what I'm seeing, it appears that /dev/sdb1 was mounted automagically by dolphin when you clicked on it. That's why it's mounted in /media.

How you should set things up really depends on how you want to access and/or use those other partitions. IMO, the hard drive partitions are easiest to access if they're mounted via fstab. The USB drives are usually best done by HAL/UDEV - which means just plug them in when you want them and let the system mount them by clicking on them via the Device Notifier in your Panel.

Depending on the partitions you usually need only add users and noauto to your fstab options thus allowing you to mount them as a user (by clicking on them in dolphin for example), but not mounting them at boot time.

Another tip is to label all your partitions. The drive labels can be used for fstab mounting if you wish and they will show up in Dolphin helping you keep track of what's what. You can label an unmounted partition in a terminal using e2label or almost any partition manager.

Here's an example of an fstab entry using the label mounting and my preferred options;

Code:

/dev/disk/by-label/sdd5     /mnt/sdd5    reiserfs   defaults,noatime,nodiratime,notail,noauto,users  0    0
