How to keep your hard drive healthy

When it comes to computer repair, hard drive failures are one of the top issues I deal with. A failed hard drive can be disastrous. But with some regular maintenance, you can keep your hard drive spinning like a top. Here's how to keep your hard drive healthy.

How to keep your hard drive healthy

Hard drive failures fall into two (2) classes: Predictable and Unpredictable. Predictable failures arise from mechanical wear and the eventual degrading of the storage surface. Unpredictable failures come from parts becoming defective or sudden mechanical failures. Around 60% of hard drive failures are from gradual wear and tear from daily use. With regular maintenance, you may be able to find, fix and repair problems before they become catastrophic.

CHKDSK (check disk)

Every operating system has a built-in utility for checking the health of your hard drive. In the early years of Windows (when it ran on top of DOS) there was ScanDisk. Then when Microsoft came out with Windows NT and NTFS, the disk checking utility changed to CHKDSK and is still in use today. The functionally has been expanded but the commands have changed very little. CHKDSK verifies the integrity of the file system and fixes logical file system errors. It can also check for bad sectors and mark them as bad, but it cannot repair them. Cost: Free

Manufacturer's software

Almost all hard drive manufacturers have utilities to check their drives for errors. Their software can check the SMART (Self-Monitoring, Analysis and Reporting Technology) status and test the physical condition of the hard drive. Best of all, their software can re-map bad sectors to spare sectors. You can find the majority of diagnostics software on the manufactures' website or use the version included in the Ultimate Boot CD (recommended). Cost: Free.

SpinRite from Gibson Research Corporation is a magnetic storage data recovery, repair and maintenance utility. The way it works is quite ingenious. It reads the data from each sector, inverts it and then writes it back to the drive. It then reads the same sector, inverts the data and then writes it back to the drive in the original format. If it can read, invert and write to a bad sector, it can clear the bad sector flag and make it usable again. SpinRite also has a feature called DynaStat that can reassemble missing data from bad sectors. Cost: $89.
