Bit Rot, And How Important Is This For Audiophiles
Usually I refrain from blogging computing technical stuffs on Snakeoil. This article will be a rare exception, today I would like to talk about bit rot. This is something you guys should aware of (but not alarmed).
This article will briefly describe:
- What is bit rot
- What bit rot means to an audiophile
- My personal experiences with bit rot
- How to detect if you are affected with bit rot
- Strategies to prevent bit rot
Hopefully after reading this article you’re more aware of what bit rot is and how to counteract it. Before we start let it be made clear that bit rot is not a big problem. There is no reason to panic and the sky is not going to fall over.
Let us begin!

It does a four-weekly scrub which detects and corrects bit rot on the whole file system. While bit rot isn’t a problem for me, it never will be.+1. FreeNAS for the win.
Maybe it’s Cosmic Rays: https://science.slashdot.org/story/17/02/19/2330251/serious-computer-glitches-can-be-caused-by-cosmic-rays
A "single-event upset" was also blamed for an electronic voting error in Schaerbeekm, Belgium, back in 2003. A bit flip in the electronic voting machine added 4,096 extra votes to one candidate. The issue was noticed only because the machine gave the candidate more votes than were possible. "This is a really big problem, but it is mostly invisible to the public," said Bharat Bhuva. Bhuva is a member of Vanderbilt University’s Radiation Effects Research Group, established in 1987 to study the effects of radiation on electronic systems.
Here is an interesting YouTube video about bit flipping.
I don’t believe bit rot is a problem and the Red Book standard copes with missing bits, to a point.
I store all of my music (FLAC, level 8 compression) on a NAS, using FreeNAS. It does a four-weekly scrub which detects and corrects bit rot on the whole file system. While bit rot isn’t a problem for me, it never will be.
