Hard drives are very delicately designed mechanisms, where, simply, an arm with a reading head floats less than a millimeter above the hard drive platters. While hard drives are designed to survive a good deal of wear and tear, any jarring of the drive can cause the reading head to touch the platter, damaging the drive, causing bad sectors.

when the sector is incapable of storing bits of data or data stored on that part cannot be read by the hard disk, it is mark as a bad sector. Usually, it is caused by dropping the hard disk, due to power fluctuations or by natural cause - the wear and tear theory.

I would back up the data on that drive ASAP because bad sectors tend to multiply and the drive dies.
