I have a FUJITSU/SIEMENS AMILO L6820 and it is 4 years old. Since yesterday, it is impossible to open Studio 9, the light glitters but it does not open, even after 15 minutes. Thinking there must be a virus on the HD, I decided to format it. But, after many tries, the Recovery CD did not function at all. I used F12 Boot Device: ATAPI CD ROM does not work, the HD starts the computer but not the Recovery CD and NSC DP83815/DP83816 MACpHYTER does not start the CD Recovery. Start Execute does not work either. I went to Verfication of C: and selected seek and recuperate sectors which are defected. ALL THIS TO NO AVAIL. How can I format the HD if the Recovery CD does not work at all?
