Over the years, I have become much more concerned with making restorable backups onto external media than with reviving slightly beginning to fail platter-driven hard-drives. Back then, I used Spinrite before and after backup or restore operations ground to a halt. Now, I systematically, routinely, make backups while the hardware and software are working together seamlessly. I average two C-partitions and two D-partition backups about every two weeks. Now, I do use HardDisk Sentinal to periodically run short quick tests on current internal and external platter-driven hard-drives.
+1 to both lcoughey and drc!
