Well, I'm using the Disk Doctor feature of AVG PC Tune up. I got a popup stating that my drive has errors. So I started the thorough disk analysis. It went well for the first two rounds and then it got stuck at about 70% of the third round and it has been there for the past one and half hour. And the drive is also inaccessible. What should I do? Can I cancel it? Will my data be lost?
