1.If data comes in faster than backups, and is precious, consider RAID 1, RAID 5 or RAID 10 disk configurations. A RAID array will keep running when one physical drive dies. A good one will even re-write a replacement drive that's "hot swapped" into it without stopping. External controllers will do this better than ones integrated into motherboards.
2.Programs like GRC's Spinrite does an excellent job at getting down to every last bit and ensuring that everything is working on the most basic of levels, however, if it finds that a sector of a hard drive is corrupted, it will attempt a recovery of it. It has saved many hard drives from failing, and has helped recover gigabytes of data. Spinrite is in its 6th version and has proven very successful. Please note, while Spinrite and other software hard disk recovery programs work well, they will not permanently fix a problem every time. Therefore, it is recommended that software recovery only be used to backup the data.
3.Some programs, such as Spinrite mentioned above, perform maintenance on hard drives to prevent flaws from forming.
