On the evidence available your hard disk is failing.
It is a common misconception that chkdsk can repair bad sectors, it cannot, it simply attempts recovery of the data from the bad sectors and rewrites it to good sectors.
There is no way of knowing how long it will take to fail completely, an increasing number of bad sectors is a severe warning that the disk is likely to fail at anytime.
