Was I surprised to run across this on Pinterest. I can't wait to try it and had to share this now.

Wow! I've taken a sledge hammer to many hard drives from defunct computers, and they are difficult to destroy. I'll have to check this out when I have another computer go bad.

Good recycling idea,To make it more appealing for carving tool sharpening just an initial change to the first stick on piece.

Rather than sticking on a carborundum pad use a velcro pad (hook piece) which could be cut from an adhesive pad or built up using strip material .

This would then allow differing Grit size carborundum pads to be used, for a similar one I have made and used in my hand drill I stuck a leather pad to one of the carborundum pads ( a500 grit 0ne) and this makes a good power strop. The main advantage with the drill is its reversible so setting it to turn away from the blade is easy and safer.

the magnets inside those are also very good rare earth magnets, very strong

I am not well versed on the mechanics of computers what is the RPM on those ? Can you control the RPM. It may not be fast enough to heat up the blade but it does not take much. The slower the RPM's the more control you have over how much metal is being removed also. I have had to totally regrind tools because I took off to much to fast in one area of the cutting edge using to high of a RPM.

I saw this awhile back too. To state the obvious, you would have to fix an abrasive sheet to the disk and you would need the appropriate power supply to run it. If you have access to PC parts, the PC power supply already has the needed connectors attached. Disk speed is constant and I question how much torque the typical hard drive develops. I also wonder how loading affects the rpm. Typical laptop drives spin at either 5400rpm or 7200rpm, though some server-based platters spin at up to 15,000rpm.
