I installed Raspberry Pi OS on my first Pi (a Pi 2 Model B, 2015) using Win32 Disk Imager. That flash took about 10 minutes over USB 2.0, and I spent another 20 minutes trying to figure out why it wasn’t booting (I’d flashed the wrong .img, a laptop restore image instead of Raspbian). I’ve … Read more
Open balenaEtcher 2.1.4 on Windows 11 24H2 and you get a dark wizard, three giant buttons, a satisfying flash-success animation, and a memory footprint that hovers around 412 MB while sitting idle. Open Win32 Disk Imager 1.0.0 (still the March 18, 2017 build, still the current SourceForge release in April 2026) and you get a … Read more
I helped a friend troubleshoot this exact problem last month. He’d installed Win32 Disk Imager on his new Windows 11 laptop (Ryzen 7, fresh out of the box, 24H2 build). Double-clicked the Start Menu shortcut, nothing happened. No error, no splash screen, no process in Task Manager. The app just refused to launch. He’d tried … Read more
The SD card in my Home Assistant Pi finally died two weeks ago. Not a slow death with warning errors, it just stopped booting on a Tuesday morning. Pulled the card, read errors from the reader, confirmed it was toast. 18 months of continuous writes finally used up the flash endurance. But I had a … Read more
My Home Assistant Pi 4 has been running for 18 months. Zigbee2MQTT with 47 devices paired. Frigate NVR with four cameras. Node-RED flows I’ve tweaked at 2am in three different time zones. The SD card is a SanDisk Ultra 32 GB that’s probably done 400 GB of writes by now and is starting to throw … Read more
I’ve flashed at least 200 Raspberry Pi SD cards in my time. For my own Pi cluster, for friends’ first Pi 5 builds, for a Home Assistant box, an OctoPi 3D printer, three retro emulation handhelds, and a frankly embarrassing number of Pi Zeroes that I then lost in drawers. For most of that history, … Read more
I get asked this question maybe once a week. “Which one should I actually use, Win32 Disk Imager or Rufus?” My honest answer is “both, for different jobs.” I’ve been flashing USB sticks and SD cards for about 15 years now, across maybe a thousand separate images, and these are the two tools I keep … Read more
The first time I hit “Error 5: Access Is Denied” in Win32 Disk Imager was at 2am on a weeknight, trying to flash a Raspberry Pi OS image onto a SanDisk Ultra 32 GB. Click Write. “An error occurred when attempting to write data to handle. Error 5: Access is denied.” Nothing I did fixed … Read more
