Fixing A JMicron-Based M.2 USB Enclosure That Stopped Working

July 30, 2026 by Maya Posch 10 Comments

As useful as USB-to-M.2 SSD adapters are, sometimes you come across a bit of a dud. A case in point is the Orico-branded TCM2-C3 that features both an attractive clear case and in its earlier revisions a JMicron controller-based circuit that apparently degrades over time, causing erratic boot behavior. After implementing a fix a few years ago, [Mark Furneaux] can happily report that the thus fixed enclosures are still working.

These faulty board revisions feature the JMicron JMS583 controller IC, which has a 1.0V core voltage input pin. Apparently to save power, Orico designed the board to target the minimum ~0.95V core voltage per the datasheet. Apparently due to component drift or degradation, this lower core voltage is after a while often not enough any more to start the controller, which thus translates into an unresponsive USB device and presumably some panic about lost data.

Although [Mark] doesn’t describe the fix in detail, it entails bumping up this core voltage to something closer to the nominal 1.0V, which restores functionality at the cost of presumably a measurable amount of extra heat production by said controller.

Later versions of the Orico TCM2-C3 enclosure switched from this JMicron controller to a Realtek one, which so far appears to be noticeably more reliable. Although Orico kept the same model name, the transparent enclosure makes it at least a snap to see which revision you are dealing with.

Old SSDs Find New Life As Game Cartridges

July 20, 2026 by Tyler August 24 Comments

Game companies might not like physical media much anymore, but gamers sure do. There’s nothing like pawing over your collection to find what to play, and inserting a cartridge with a satisfying click before sitting down to an old-school game like — wait, Cyberpunk 2077? Yeah, that wasn’t released on cartridge, but that didn’t stop [LewdMeat]. The cartridges are 3D printed and contain old 2.5″ SSDs picked up for cheap in bulk.

This larger base seems ideal for building into a PC console, but either would work.

Inside the base unit is a simple USB3-SATA adapter that hooks to [LewdMeat]’s gaming PC. There are two versions of the base: a simple vertical unit, and a horizontal one with some springs to give a satisfying grip. On each disk is a launch script that is vetted by a program on the PC that auto-launches only the cartridges you’ve told it to trust, which is a level of security we can appreciate.

We don’t know how much life is left in these cheap drives, but they should last a while if the only write is the odd save file. Hopefully [LewdMeat] is cycling through his games fairly often, as SSDs are only non-volatile storage if your time horizon is short enough.

Thanks to [iliis] for the tip! Remember, if you use our tips line to share what you find, you’re not doomscrolling, you’re doing a public service.

Hackaday Links: March 29, 2026

Whether it’s a new couch or a rare piece of hardware picked up on eBay, we all know what it feels like to eagerly await a delivery truck. But the CERN researchers involved in a delivery earlier this week weren’t transporting anyone’s Amazon Prime packages, they were hauling antimatter.

Moving antimatter, specifically antiprotons, via trucks might seem a bit ridiculous. But ultimately CERN wants to transfer samples between various European laboratories, and that means they need a practical and reliable way of getting the temperamental stuff from point A to B. To demonstrate this capability, the researchers loaded a truck with 92 antiprotons and drove it around for 30 minutes. Of course, you can’t just put antiprotons in a cardboard box, the experiment utilized a cryogenically cooled magnetic containment unit that they hope will eventually be able to keep antimatter from rudely annihilating itself on trips lasting as long as 8 hours.

Speaking of deliveries, anyone building a new computer should be careful when ordering components. Shady companies are looking to capitalize on the currently sky high prices of solid-state drives by counterfeiting popular models, and according to the Japanese site AKIBA PC Hotline, there are some examples in the wild that would fool all but the most advanced users. They examine a bootleg drive that’s a nearly identical replica of the Samsung 990 PRO — the unit and its packaging are basically a mirror image of the real deal, the stated capacity appears valid, and it even exhibits similar performance when put through a basic benchmark test.

A Friendly Reminder That Your Unpowered SSDs Are Probably Losing Data

November 26, 2025 by Zoe Skyforest 49 Comments

Save a bunch of files on a good ol’ magnetic hard drive, leave it in a box, and they’ll probably still be there a couple of decades later. The lubricants might have all solidified and the heads jammed in place, but if you can get things moving, you’ll still have your data. As explained over at [XDA Developers], though, SSDs can’t really offer the same longevity.

It all comes down to power. SSDs are considered non-volatile storage—in that they hold on to data even when power is removed. However, they can only do so for a rather limited amount of time. This is because of the way NAND flash storage works. It involves trapping a charge in a floating gate transistor to store a single bit of data. You can power down an SSD, and the trapped charge in all the NAND flash transistors will happily stay put. But over longer periods of time, from months to years, that charge can leak out. When this happens, data is lost.

Depending on your particular SSD, and the variety of NAND flash it uses (TLC, QLC, etc), the safe storage time may be anywhere from a few months to a few years. The process takes place faster at higher temperatures, too, so if you store your drives in a warm area, you could see surprisingly rapid loss.

Ultimately, it’s worth checking your drive specs and planning accordingly. Going on a two-week holiday? Your PC will probably be just fine switched off. Going to prison for three to five years with only a slim chance of parole? Maybe back up to a hard drive first, or have your cousin switch your machine on now and then for safety’s sake.

On a vaguely related note, we’ve even seen SSDs that can self-destruct on purpose. If you’ve got the low down on other neat solid-state stories, don’t hesitate to notify the tipsline.

Back in March, we covered the story of Davis Lu, a disgruntled coder who programmed a logic bomb into his employers’ systems. His code was malicious in the extreme, designed as it was to regularly search for his Active Directory entry and fire off a series of crippling commands should it appear he had been fired. His 2019 sacking and subsequent deletion of his AD profile triggered the job, wreaking havoc on servers and causing general mayhem. Whatever satisfaction Lu drew from that must have been fleeting, because he was quickly arrested, brought to trial in federal court, and found guilty of causing intentional damage to protected computer systems.

Lu faced a decade in federal prison for the stunt, but at his sentencing last week, he got four years behind bars followed by three years of supervised release. That’s still a pretty stiff sentence, and depending on where he serves it, things might not go well for him. Uber-geek Chris Boden has some experience in the federal prison system as a result of some cryptocurrency malfeasance; his video on his time in lockup is probably something Mr. Lu should watch while he can. Honestly, we feel bad for him in a way because we’ve been there; we certainly toyed with the logic bomb idea when we were coding for a living, without actually ever doing it. Maybe he thought it would just get treated as a prank, but that was probably never in the cards; as we’re fond of telling our kids, the world just doesn’t have a sense of humor anymore.

Kali Cyberdeck Looks The Business

August 7, 2024 by Dan Maloney 17 Comments

Even though we somewhat uncharacteristically don’t have a cyberdeck contest currently underway, there’s never a bad time to get your [Gibson] on. That’s especially true when fate hands you an enclosure as perfect as the one that inspired this very compact Kali Linux cyberdeck.

Now, that’s not to say that we don’t love larger cyberdecks, of course. The ones built into Pelican-style shipping containers are particularly attractive, and it’s hard to argue against their practicality. But when [Hans Jørgen Grimstad], who somehow just sounds like a person who should be building cyberdecks, found a new-old-stock stash of US Army Signal Corps spare parts kits from the 1950s, designation CY-684/GR, he just had to spring into action. After carefully gutting the metal case of the dividers that once protected tubes and other parts, he had some PCB panels made up for the top and bottom. The bottom had enough room for a compact USB keypad, with room left over on the panel for a cooling fan and various connectors. A 7″ HDMI display was added to the panel on the top lid, while a Raspberry Pi 5 with a 500-GB NVMe SSD went below the lower panel. The insides are properly decorated with cyberpunk-esque regalia including a “Self Destruct” button. Sadly, this appears to be unimplemented in the current version, at least for the stated purpose; there’s always hope for version two.

While we love the look and feel of this build and the subtle nods to the cyberpunk aesthetic, it sure seems like you could get some serious work done with a deck like this. Hats off to [Hans] for the build, and here’s hoping he left some of those cool cases for the rest of us.

JTAG Hacking An SSD With A Pi: A Primer

May 12, 2024 by Arya Voronova 4 Comments

[Matthew “wrongbaud” Alt] is well known around these parts for his hardware hacking and reverse-engineering lessons, and today he’s bringing us a JTAG hacking primer that demoes some cool new hardware — the PiFEX (Pi Interface Explorer). Ever wondered about those testpoint arrays on mSATA and M.2 SSDs? This write-up lays bare the secrets of such an SSD, using a Pi 4, PiFEX, OpenOCD and a good few open-source tools for JTAG probing that you can easily use yourself.

The PiFEX hat gives you level-shifted bidirectional GPIO connectors for UART, SPI, I2C, JTAG, SWD and potentially way more, an OLED screen to show any debugging information you might need, and even a logic analyzer header so that you can check up on your reverse-engineering progress.
