Don't wipe hard drives.

HDs used to be expensive and the odds of unwiped data being exploited were small. Now HDs are cheap and the odds of unwiped data being exploited are much higher. HDs, even large ones go for a few hundred dollars whereas identity theft can cost you thousands of dollars and months of effort.

HDs are also much larger than they used to be so any wiping program takes much longer. A terabyte drive can take a very long time to wipe. Particularly when you use any of the better multi-pass procedures.

Save yourself time and effort and absolutely remove any chance anyone will find any data left behind by pounding your unwanted HDs discs to rubble. Takes about two minutes with a hammer if you don't disassemble the HD. Once the discs shatter they are essentially impossible to read by conventional means. No need to acid etch or wire brush anything. Disassembly takes another five minutes. As a bonus, once disassembled you get a nifty magnet to play with.

SSDs use an entirely different storage technique and they are both easier to wipe, harder to recover any wiped data from, and there is no need to destroy them to keep the data safe. A good thing because SSDs are still expensive.

Added a few sentences for clarity.
