You could try to put it back but I found this on SMART analysis:
It's a hardware problem that has nothing to do with the issues we were working on.The SMART hard drive technology, available in IDE and SCSI, is designed to constantly monitor drive activity and to predict failures before they occur. The drive tracks fault prediction and failure indication parameters such as re-allocated sector count, spin retry count and calibration retry count. If the drive determines that a failure is imminent, it passes this information to management software, which generates a fault alert.
These failures can be caused by static electricity, handling damage, or thermal-related solder problems, and there is nothing that can be done to predict or avoid them. In fact, 60% of drive failures are mechanical, often resulting from the gradual degradation of the drive's performance.
Please check this table to see what your problem is to be more exact.
