It results from the gradual decay of storage media over the course of years or longer. Causes vary by medium. + +**For more information** see [Wikipedia - Data_degradation](https://en.wikipedia.org/wiki/Data_degradation). + This is the successor to [chkbit/node](https://github.com/laktak/chkbit-py). It will use and upgrade the index files created by the node version. ## Installation
