Bad Sector causes

by Shanghai Sam In reply to Bad Sector causes

True bad sectors (not viruses) are usually caused by the read/write head hitting the disk. (The head is supposed to "fly" above the disk surface on an air cushion. Sort of like a surfer.) If the head hits the disk damage occurs. If you take apart anold 100 meg drive that has bad sectors, you can see the scratches and marks on the disk platter. Disk utilities, do not repair the damaged sectors on the disk, they only mark them as bad. The OS knows not to use these marked sectors, so the OS skipsthem when writing data.
If you are starting to get bad sectors on your hard disk, this is one of the surest signs that the hard drive is near the end of its life. If the hard drive is not old, check for excessive vibration or heat. (Bad environment.)

Bad sectors are also caused by not shutting down windows properly and may be repaired by scandisk or if not your only true last hope to save your hard drive is by using a disk utility called SPINRITE and you can download it by logging onto WWW.GIBSONRESEARCH.com(AWESOME UTILITY)

Imperfections in the drive media which degenerate over time can appear as bad sectors. Scandisk does not repair bad sectors only marks them as bad. You can only recover 'bad' sectors by formatting but the effect will be temporary untill you try writing to the faulty sector again.

You can either hit the reset button 100+ times on your computer, or you can dismantle your hard drive. and the bad sectors can be repaired by using scandisk, or Scandisk for windows. To delete bad sectors, reformat your hard drive. If your bios supports reformatting, do it through there.

Bad sectors are caused by a variety of things, some of which have been described in previous answers. There is no way to get rid of them - or avoid them - without some kind of disk utility.
