Which partition is / and which is /home?

[RayArdia]

After much advice from various expert contributors I have finally got a dual boot Ubuntu 13.04 and Win7. The Win7 OS on /dev/sda1 works OK, and as it's only purpose in life is to allow me to run Sketchup, all is well.
When it comes to the other 3 partitions I' a bit confuse as to which Ubuntu is using as / and which as /home.
Output s follow:-

I thought I had Ubuntu in the smaller sda3 and that sda4 was being used for /home but when I try to reload backup copies of files from sdc into my Home directory Iget an error that 'nautilus hsn't got enough room for the operation' or something similar.

Yes, that's what you did.

The exact error message would be more helpful. Nautilus is an application, not a partition.

Are you trying to copy all the files from the sdc partition to the home partition?
If so, then the error makes sense. The sdc partition has a larger used space than the home partition's available space.

[RayArdia]

Yes, that's what you did.

Thanks to you and to deadflowr for your help will look out for the error message next time. Incidentally, what tells you that the one is / and the other is /home?
Yes I know that the total size of the used space in /sdc1 is greater than that of /sda3 but I was only trying to move a folder of about 4GB.

Are you running a Ubuntu live session? or perhaps have the live session disk in the drive and mounted?

Regards.

The OP has the "Ubuntu 13.04 Live DVD" mounted, as /dev/sda3 is the / (root) directory in this case.

I wasn't running a live session but had left the disk in the drive! How stupid of me; apologies for the silly question.

No, ubuntu doesn't have only 794 MB. That's the size of the DVD installer.

/dev/sr0 is usually the CD and/or DVD and/or BluRay drive.
