I am a new user of Ubuntu. When I type df -h in terminal , it gives me list of all storage devices and space usage. In my system I get this.

Filesystem      Size  Used Avail Use% Mounted on
/cow            934M  173M  761M  19% /
udev            925M  4.0K  925M   1% /dev
tmpfs           374M  856K  373M   1% /run
/dev/sdb1       7.5G  2.8G  4.8G  37% /cdrom
/dev/loop0      1.5G  1.5G     0 100% /rofs
tmpfs           934M   16K  934M   1% /tmp
none            5.0M     0  5.0M   0% /run/lock
none            934M   76K  934M   1% /run/shm
/dev/sda        299G   74M  299G   1% /media/q

I understand that /dev/sda is my hard drive which is 320 gb(in gib it is 299 and hopefully that is what is being displayed) and /dev/sdb1 is pendrive of 8gb from which I am running the live cd.

My question is what are the other folders and what is the physical location of these folders if complete memory is taken by the device dev/sda?

can you post your /etc/fstab entry here. it looks like you created a label... –  max Sep 28 '12 at 12:06

df -h shows information about space on all currently mounted file systems. They can be different partitions, devices or just folders brought up to their location through the mount command. You can have a look at /etc/fstab to see where they come from.

@Esha: start by reading man fstab ask a new question about anything that isn't clear. –  RedGrittyBrick Sep 28 '12 at 10:32
