Hi,
I need to remove a current hard drive and insert a new one. I want to make sure that the old hard drive does not have any data on it. My system currently has 1 windows sata drive, 1 80 GB and a 12 GB. The 12GB is going to my sister. The problem is I don't know wether my 12 GB hard drive has any data on it or not. When I run df I get this
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
87793968 9923700 73410544 12% /
/dev/hda1 101086 25687 70180 27% /boot
none 517636 0 517636 0% /dev/shm
/dev/sda1 117210208 106434768 10775440 91% /mnt/Windows
I don't know what the /dev/mapper/Vol.... thing is doing for me. I usually see lines like /dev/hda1 /dev/hda2 /dev/hdb1 etc. I have FC3 with kernel 2.6.11-1.14_FC3.
If I run fdisk I get
Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 14592 117210208+ 7 HPFS/NTFS
So i know these drives are recognized in their current sizes. Can anyone explain the mapper, tell me how to disable it (if possible), move the data from the 12 GB to the 80 GB, and how to remove the hard drive safely from linux without causing any problems (unmounting etc)? My goal is to not have to install FC3 fresh...again?
Here is my /etc/fstab file if that helps
