Tipping my hat to PRX's Remix Radio blog, this is a funderella and/or geekerama source of sounds.

These are some typical sounds we hear in our data recovery lab. If your hard drive makes noises like these and you are still able to access your files - backup immediately. If you no longer can see the drive please fill out our simple evaluation form to get a fast quote on our data recovery services.
To listen to the sound simply click on the play button(one at a time). It may take some time to load. Click on the drive manufacturer next to the sound button to learn more about common problems these drives experience.
If you want to use these sounds in your music (yes, we have received lots of requests already) - no problem, but please contact us first.
