Harvesting audio data from a full SD card

This document covers copying audio files from a Solo’s memory card safely onto your PC/laptop.

You should physically insert the card into a “card reader” which may be integrated into your PC/Laptop or might be a seperate component that connects to your PC via USB.

Once the card is connected, the PC will recognise the card, and the audio will become available to copy. You should ensure that you have sufficient storage on your PC to handle all the audio data files (Solos can collect a LOT of data).

Once you have safely copied the data, you should consider the contents of the memory card to be useless, reflash the card. Note: Deleting the audio and re-using the card in a Solo without reflashing - might work, but is not recommended. Always use a freshly flashed memory card when you prepare a Solo.

Depending on your computer’s operating system (Windows, Mac, Linux), slightly different procedure is needed:


Install Linux_reader. This software will be able to copy the audio files from the audio card.


Just plug it in, and a drive called “solo-audio” will appear.


Just plug it in, and a parition called “solo-audio” will appear.

Technical note

This is to do with partitions. Windows won’t read a second and third partition from a memory card, instead turning a blind eye. Mac and Linux do it natively.

Obtaining and installing Linux_reader

Having deployed a Solo and returned with an SD card full of audio recordings, they need to be copied to your PC’s hard drive. This tool does that copying. It is available for free download from http://www.diskinternals.com/linux-reader

Once downloaded, it should be installed on your PC. Consider making a shortcut to it, as it will be used every time you wish to copy audio from the SD card onto your PC. Further details of this tool are available from its website, if you are interested, or need more help.
