Solve: Introducing nvme_check.sh – A Safe, Friendly NVMe Diagnostic Tool for Raspberry Pi







Working with NVMe drives on the Raspberry Pi 5 is exciting—but it can also be frustrating. Most users aren’t sure if TRIM is working, or if their drive is mounted correctly, or why performance seems to drop over time. Worse, the common tools (hdparm, nvme-cli, fstrim, etc.) each speak their own strange dialect.

So we built a tool to make it all easier.

nvme_check.sh is a lightweight terminal script designed for Raspberry Pi users running Raspberry Pi OS or Armbian. It wraps essential Linux commands in a simple, menu-based interface—no background changes, no risk, no guesswork.


🛠 What It Shows You
  • Which NVMe drive is connected (and how big it is)
  • Whether it’s mounted properly and which file system it uses
  • Whether TRIM is supported, working, and scheduled
  • If the discard option is present for live TRIM
  • A quick, safe 100MB read/write test
  • NVMe health info via nvme smart-log
  • An exportable session log you can share or save
All logs go to ~/nvme_check_session.log and can be reviewed or copied using option [8].


🧪 Why We Built It

We ran into a real-world issue helping a fellow Pi user who was trying to diagnose an NVMe slowdown. What should’ve been a few quick commands turned into a mess of hdparm confusion, missing nvme tools, and uncertainty about whether anything was actually working.

That’s when we realized: there's no "one screen" tool for checking NVMe health on a Pi. So we made one.


💾 Try It Now

You can download the script and find full install instructions here:

If you’re a Raspberry Pi 5 user experimenting with NVMe drives, this tool is for you. If you’re running Debian Bookworm, Raspberry Pi OS, or Armbian—you’re covered.

The New ChatGPT Reason Feature: What It Is and Why You Should Use It Offers More Than Just a Simple Answer ChatGPT continues to evolve, constantly introducing new features that make user interactions more tailored and insightful. One of the latest additions is the Reason option, which you can access through the slash menu. At its core, this feature gives you more control over the depth of responses, specifically when you’re looking for more than just a simple answer. In this article, we’ll explore what the Reason feature is, where it originated, why it matters, and how you can make the most of it. What Is the Reason Feature? The Reason option prompts ChatGPT to provide a detailed, structured explanation that dives into the reasoning behind an answer. It focuses on giving a logical breakdown of how the conclusion was reached, rather than just providing a surface-level response. Essentially, it’s a way of saying, "I want to understand not just the answer, but the reasoning behind it...

Raspberry Pi Connect vs. RealVNC:  A  Comprehensive Comparison The Raspberry Pi has revolutionized the way we interact with computers, providing a low-cost, highly adaptable platform for countless applications. One critical aspect of using a Raspberry Pi, especially for remote management and control, is the ability to access it from another device. Historically, RealVNC has been the go-to solution for this purpose. However, the recent introduction of Raspberry Pi Connect offers an integrated alternative. This article will compare Raspberry Pi Connect and RealVNC, exploring their features, requirements, and practical applications. Introduction to Raspberry Pi Connect Raspberry Pi Connect is a new VNC service directly integrated into Raspberry Pi OS 12. Designed for simplicity and ease of use, Connect aims to provide a seamless remote desktop experience for Raspberry Pi users. Currently in beta, Raspberry Pi Connect is free to use and requires a Raspberry Pi 4, 400, or 5 running...

The Reasoning Chain in DeepSeek R1: A Glimpse into AI’s Thought Process Imagine a user interacting with DeepSeek R1, searching for documentation on the model. They enter the following prompt: User: Where is user documentation for DeepSeek-R1? DeepSeek R1 - Reasoning Chain Output: Okay, the user is asking about DeepSeek-R1 again. I remember they previously asked for user documentation, and I provided some general steps, but now they want a description. Let me check if there’s any new information post my knowledge cutoff in July 2024. Wait, DeepSeek-R1 wasn’t in my training data up to July 2024. But maybe it’s a model they released after that. The user might be referring to an AI model by DeepSeek, given the context of previous questions. In their previous interaction, I mentioned checking official sources like GitHub or the DeepSeek website. Now, they want a description. Since I don’t have specific data on R1, I should proceed carefully. Maybe there’s some informat...
