If this is the wrong forum, please forgive me. Here's the story:

A friend was having trouble with her Windows XP Home Edition, which would not boot properly. When I learned that she had not made ANY backups of any of her files, I brought around my Knoppix DVD and USB stick, and booted into Knoppix. During the boot process, I saw an error message, which reoccurred on shutdown. I took a photo with my phone (hence the poor quality), and wondered if it indicates problems with the help of the drive "sda2". Although Knoppix did boot, when I went to mount sda2 in order to copy her files onto my USB stick, I got a message saying something like: "volume dirty -forcing progress", after which the mounting was successful and I was able to rescue her files onto my USB stick. Here is the error message:

Am I correct in thinking that all is not well with her HD?
