Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

fdisk (in the first form of invocation) is a menu driven program for creation and manipulation of partition tables. It understands DOS type partition tables and BSD or SUN type disklabels.
The device is usually one of the following:
/dev/hda /dev/hdb /dev/sda /dev/sdb
(/dev/hd[a-h] for IDE disks, /dev/sd[a-p] for SCSI disks, /dev/ed[a-d] for ESDI disks, /dev/xd[ab] for XT disks). A device name refers to the entire disk.
The partition is a device name followed by a partition number. For example, /dev/hda1 is the first partition on the first IDE hard disk in the system. Disks can have up to 15 partitions. See also /usr/src/linux/Documentation/devices.txt
Email messages for a user.
Weakly ones I made a whole system backup (dd if=/dev/hda of=/dev/hdc), so I copy the entire primary HDD on the secondary HDD. My last update were made 5 days ago. Yesterday my linux system was crashed down (perhaps because of power - I couldn't start it). It's not problem, I just changed the HDD's and my system worked again with 5 days old datas. But the big problem is, that one of my users got a very important message (email message) 3 days ago (so this message was not backuped, but this message is on the another HDD witch doesn't start).
So my problem is this mail. This mail is no the hdc (/home/user) but I don't know how to access it.
Do you have any idea?
So you can start yor system now with the backup hdd. And as far as I understand you
physical moved the discs. So how about if you just mount that disk in to a mount dir on your working system?
Like mount /dev/hdc2 /mnt/disk
