Hello dear people Can a virus or several viruses damage a hard disk in such a way that it cannot even be used physically (i.e. after it has been formatted). An acquaintance of mine had this case. The service technician said that after a massive virus attack, your hard drive would only be a case for the trash can. As far as I know, viruses can "only" make the data on a hard drive completely unusable and in extreme cases the hard drive can then be used again after formatting. Is it? Thank you for your answers Greetings Igor

Hello Igor,
i would love to hug the service technician tightly and send him back to school.
You are right when you say that a virus cannot destroy hardware. Be it hard drive, monitor (also mentioned again and again) or optical (CD-DVD) drives or whatever else you have in or around the PC.
Refuse all payments to the service technician, have the hardware handed over in the delivery condition and look for a reputable one is most appropriate.

I see exactly that way. To damage a hard drive you need physical force (hammer, fist, Tesla, booster rockets, collapsing buildings ......)
A virus can at most write to the MBR, but you can fix it quickly and a professional should know how to do it.

If the service technician does not know this command, he is a service fool.

The only thing you can do with Virus is to deactivate the cooling in some systems, but the embedded controller is able to shut down the system at 99 ° C.

A malicious program cannot destroy hardware; However, it is entirely possible to make a hard disk unusable by exploiting gaps in the disk's firmware to inject senseless configuration data into the disk so that it can no longer be recognized by the BIOS or the read / write head tries to access non-existent tracks (which can lead to mechanical damage in the long term).

However, it cannot do any harm to run appropriate tests with the hard disk manufacturer's diagnostic program.

Answer 4 from MacGyver031

by exploiting gaps in the firmware of the disk

With the huge number of hard drives, models and sizes, someone really had to know the PC and write a virus especially for this type of hard drive.

The read / write head tries to drive to non-existent tracks

This was possible with the Commodore 64 and its floppy disk drive, today it is no longer the case!

Use the hard disk manufacturer's diagnostic program to perform appropriate tests.

The service idiot should do that! and don't kidding people.

Answer 5 from igor

hi Guys
Thank you for your answers. I think the service technician should be given some tutoring. Or maybe motivate him to sell curry sausages somewhere.

Nice weekend

Igor, but then you want to eat his? Who knows, he'll tell you something about the horse. Just like that. André

Answer 7 from MixMax

So I am not yet aware of any virus that exploits this vulnerability, but a malicious program can make a hard drive unusable in a form that the hard drive only reacts to a few commands (it is still recognized) but you can neither read data from it nor the Format disk (even low-level format is not possible)

More on this at http://www.heise.de/ct/05/08/172/

So before you put the technician against the wall and absolutely want to give him "tutoring" ....

When he has done his job and sold a new hard disk, have the disk handed over and see for yourself whether something can still be done. It is possible that the disk is simply defective regardless of the viruses it contains.

Answer 9 from simco

hi, i guess the hard drive is not that bad.
at least one should try to do it before the description is made, so do it (or your friend).
since you didn't mention anything about whether it would be recognized by the bios, it should be checked.
if it is recognized, then perform a low level format with the correct hard disk program: HDD diagnosis / recovery tool collection
afterwards run the tests (fast, full test takes a long time).

Kind regards

So there are really programs or viruses where the hardware in your case completely destroys the hard drive ...
