subtle

Last sunday all data on the HDD disappeared.
All the .jpg, .bmp, .doc, .txt....
After I noticed that I created some .txt files and they are still there.
In that time internet failed as well (and dosn't work still-it works on the laptop with desktop modem).
What might be the reason?

I'm doing Easy Recovery and it found arund 60GB of data.
I'm saving jpgs first, but from what I've checked most of them is damaged.
Is there way to fix them?

Any ideas?
