I remember old days when I could recognize if Hero’s Quest location had a monster by hard drive sound alone. Harder to perform such feats with newer hard drives.
Still there is one important thing about sounds hard drive makes – if they aren’t regular it is likely a problem. But how to be sure what problematic sounds are? Listen to them without waiting for hard drive to fail.
What it offers
Data Cent is Canada-based data recovery firm. On they site they offer free gallery of audio clips, recorded from failing hard drives.
Clips can be listened right on page by pressing play icons. They are grouped by drive manufacturer and for each several malfunctions are covered. There is also separate page for each manufacturer that describe drive failures, common to brand, and give some context information to the sounds.
Turns out I had never encountered drives with failing bearings. They sounds scary. :)
Very educational and useful resource that gives you precise audio samples of when it is time to save your data and change dying drive. Backup before that.
