That one's fine.

That one as well, though there's no need to match exactly with regard to
size - just make sure that the new partitions are big enough to take all the
stuff that's in the corresponding old partition. As long as you keep the
same number *and* order of partitions, you're fine[0].

Ok.

I've seen many ways to do this - cp -a is one of them and probably the most
convenient one. The "Tips and Tricks-HOWTO" shows another one, using tar.
However, you shouldn't copy the "lost+found" directories, as they'll
overwrite the ones created by mke2fs on the new drive. Also, as your old
drive is dying, maybe the old lost+found already contain some garbage, which
you don't want to copy to the new drive. I've seen a way to take care of
this automatically (I think it was on one on the RH lists), but it's been a
while and I can't remember the details, unfortunately. I think it involved
'find", but I'm not sure.
Also, do NOT copy /proc! Make a directory /proc on the new drive, but leave
it empty - it'll be used as a mount point for the proc filesystem.

Bzzt! You forgot the boot sector - the new drive doesn't have one, so the
computer wouldn't know how to boot from it... I usually do:
- MAKE A BOOTDISK!
- Shutdown, unplug old disk, plug new disk in its place
- Boot from the bootdisk
- Install Grub in the boot sector ('man grub' or whatever documentation is
relevant for Grup - I've only ever done it with lilo so far).
- Reboot
New disk in place (hopefully...).

[0] actually, you can even use a completely new partitioning scheme, but
that's advanced stuff, as you'll have to make sure the new partition
table is known to the machine (fstab, grub.conf, bootdisk, etc.), hence
more potential to make a mistake.
