That was twenty years ago (yes, twenty). Today the moving parts are much smaller, faster and suspectible to damage. If your hard disk hiccups, it means it's practically dead, it just doesn't know it yet. It seems you have the theoretical background, but you haven't recovered many hard drives in the last few years, have you?
Hardly seems worth reducing the HDD capacity to 1/10. What if the whole drive fails? Besides, in my experience, once you got one bad sector, it multiplies quickly. The only sensible thing to do is backing up to another physical drive, preferably located in a separate computer (in case of total system f**kup), and even more preferably at different geographic location (in case of fire or other disaster). Backing up on the same drive is just evil.
No way! It's true. for example if you make 10 copies of a file on a HDD, it stores on different sectors. Practically if the sector where you have the original file fails, you can skip it and get to a sector where a copy is.
Seriosly? If the drive dies then you can't get anything off of it. Backing up to the same drive will allow you to recover a file if you accidentally delete it or need to go back to an older version but it won't help if the hard dlive fails. Bacukp to another drive.
They mention about how fragile these things are. While that's true (can't drop them very far) they are also very reliable when handled properly. Hard drive failure rates are less than 1% annually. So buy 100 drives some will be DOA, aside from those, maybe 1 will actually fail out of 100. For comparison, failure rates for everything else in a computer are higher.
Very impressive considering how precise hard drives are. So yes backup but the chances of your hard drive dieing tomorrow are remote.

You can issue the HDD to skip bad sectors (reducing a little storage) and so the bad sectors will rarely multiply

No, burn your important data to DVDs or at least copy it to another computer and get a new drive <u>now.

Back up on the same drive? You're kidding, right?
