[vox-tech] Two Install Questions

I've been running Kubuntu Hardy on my laptop and desktop.  I've frozen myself 
at KDE 3.5.  But some updates ruined Kubuntu on my laptop and I installed 
Ubuntu 10.10 on the laptop.  Because I like it so much, I've decided to 
install Unbuntu 10.10 on my desktop.  This has led to two questions.

1)  During the install I am told that I have a partition called "dev/sdb1" in 
ext3.  I had no idea what that could be.  So I aborted the install, and went 
into Kubuntu to find out.  dev/sdb1 was not mounted.  But by 
executing "fdisk -l" I got this:

 Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1        1306    10490413+  83  Linux

So I mounted it to see what it was.  It's an empty directory 
called "lost+found."

What is that there?  What does lost+found do?  Why do I need it?

2)  During my laptop install I was given the choice of ext3 or ext4.  Given my 
level of expertise, I'd never heard of ext4.  By Googling, I learned that 
ext4 came out in 2008.  So you can see where I'm at.

I didn't see any negative comments about ext4 so I used it.  I'll have the 
same choice when I install on my desktop.  I assume that ext4 is the best 
choice.  Is that right?

Thank you.
