plug both drives in
Let's say the bad drive is SDA
and the new drive is SDB
assuming you used the default gentoo partitioning scheme:
A) Swap the two drives and install gentoo on the good drive (as sda)
B) Swap the drives back
C) From a livecd do this:
| Code: |
mkdir /mnt/sda
mkdir /mnt/sdb
mount /dev/sda3 /mnt/sda
mount /dev/sdb3 /mnt/sda
rsync -av /mnt/sda/home/* /mnt/sdb/home/
|

So I need to install gentoo on the new drive from a livecd?
Is it possible to format the drive from my system and then, say, cp /home/ to the new drive? |

It is not very clear to me - do you want to copy just your /home directory or the whole system?
In case you want to copy just your homedir rsyncing, as described earlier, is sufficient. You can boot from live cd or you can mount the new drive somewhere (e.g /mnt/sdab) and use rsync
| Code: | | rsync -av /home/* /mnt/sdb/ |

Of course you can. Use fdisk. First check the installed drives by issuing fdisk -l
just to make sure, you won't format something you don't want to.
In case you want to copy the whole system, assuming that your /dev/sda is not corrupted in a way, you can build a custom stage 4. http://gentoo-wiki.com/HOWTO_Custom_Stage4 |

Well Im not sure exactly what is on which drive (I have two). But I believe when I installed gentoo way back in the day, that I put /home/ on this faulty drive, so I guess I just need to mv my /home/ directory to the new hdd. Is there a way I could check what is located on my hdd?
Thanks for the help so far.  |

| Just run the "mount" command with no arguments. Also /etc/fstab will probably tell you in case you have some partitions you do not automount. |

| Since you speak of elegance, I must point out that you have engaged in a Useless Use Of Cat. When reading only one file, it is simpler to let grep read the file directly: grep -e /dev < /etc/fstab. |

Or even let grep(1) read the file directly:
| Code: | | grep /dev /etc/fstab |
