How to Test a Hard Drive on a Computer
Most of us know that an efficient utility software will extend the life and integrity of the Windows operating system and ensure that our programs run at optimal speed. What many forget, however, is that the health of the hard drive often has nothing to do with the health of our OS and a failure can occur even under the best of circumstances. Running regular diagnostics on the hard drive will give fair warning of potential failures and eliminate the possibility of data loss. Error messages, blue screens, program problems, hangs, and slow shut downs are clear signs that a PC's hard drive is not running up to par and that a disk failure may be imminent. Unless the damage is physical, there are plenty of free tools available for both analyzing and fixing hard drive performance issues:

Tips & Warnings
Never attempt to open or repair a hard disk yourself. Doing so will result in a complete loss of data beyond recovery. If your drive remains inaccessible, leave it to a Data Recovery center to retrieve important file information.
