whats are the primary causes of Harddisk bad sectors? is copying and deleting of large files i.e. 600 MB continously because of errors will cause HDD bad sectors?

 
No real way of knowing in advance if a drive will have bad sectors. Normal usage will not cause them. The most common causes are un-buffered line voltage surges; bumps or movement of the computer when the drive is active; defective magnetic media coating; power failure in the middle of a read/write cycle. There are other causes, but not normal usage.

Most new drives are "SmartDrive" capable, and if active, it will warn of impending problems. Periodic surface scan or checking will find and locate bad or weak sectors, move the data, and attempt to repair. Failing in that it will mark them and the drive will bypass them.

Just about all drives have some bad sectors even when new, but the low level formatting process marks them and makes them invisible and unusable.
