Z80 Retro #18 - How SD Cards Work

An important note from @knghtbrd You definitely gave enough warning about sda possibly being not your SD card especially on a desktop system, but … it can be your boot drive on a Raspberry Pi too. So a good rule of thumb … before you go writing over anything in /dev … check what's mounted on your system. You can do that with this command: df -H If you see sdaANYTHING there … don't run commands that overwrite it! Find out where your SD card is first and figure out how to modify the command appropriately. --- You can support this channel on Patreon!   / johnsbasement   This video is part of a YouTube playlist/series:    • Z80 Retro   The github repo seen in this video: https://github.com/johnwinans/2063-Z8...
