Hi, Magnus:

You've got a faulty hard drive, not a virus. The diagnostics are not impacted by software viruses. A new drive is not expensive. Here's one for $66. Here's the installation procedure.

You'll need to reinstall the OS, drivers and applications, obviously. Here's that procedure.

For data recovery, I would buy an external USB enclosure for 2.5" drives. But it's unlikely that you'll be able to save the data. Perhaps you should think about a data back-up plan.

Hi Osprey Thanks for the help. Okay 66 dollars is not so expensive. 

The problem is that I dont have other Cd´s other than the Dell Diagnostics CD. Do you know how much a CD with the operating system are going to cost?

Can the external USB enclosure transfer the files from the old harddisk to a new one? That would be fantastic so I can save my documents.

And yes next time I will back-up my data every month :)

Thanks again

Best Regards

Magnus

You can order replacement OS and other discs from this page. I don't believe there is any charge.

Hopefully, your drive is still readable and you can use the USB enclosure to transfer it. Good luck and let me know how things work out!

Okay thanks for your help. I will consider what to do. :)
