My hardisk has 1880 bad sectors and I am beginning to realize that it about to fail.

Is there a way using my Ubuntu OS to fix or at least partition off the part of my HD where most of these sectors are?

No doubt this is a duplicate, but the answer needs to be put up front:

Replace that hard disk NOW!! Bad sectors cannot be fixed. A small number can be worked around, but this is done automatically by the firmware in the hard disk; you should never see any sign that they actually exist unless you run a SMART test on the disk. When you start seeing bad sectors, it means that the disk is failing. The disk may continue to be usable (in a limited way) for anywhere from no time at all to months, but the problem is that these failures can and often do escalate very rapidly and without further warning -- the bad sectors are the warning. Thus, you should go to a store today, buy a new disk, and copy your data off the bad disk today. Don't mail-order a new disk to save $10, because the extra time for delivery of the disk could be the time in which you go from 1,880 bad sectors to 1,880,000 bad sectors.
