I had files, about five of them I’ve been working on for ages and storing on an SD card. The files are interconnected, like on file has others as include files, and 2 backup files. After a sudden computer power reset, all the… Continue reading Can I ever recover my missing files from SD card? [migrated]
A security risk with ordinary flash drives is that they have re-writable (flashble) firmware, which basically lets a hacker replace the operating system of the USB drive with their own.
Are there any USB drives that are guaranteed to be r… Continue reading Are there USB flash drives with read-only firmware?
[Pete] was building a hot tub controller, using a WEMOS board based on the venerable ESP8266. After assembly, the board was plugged into USB and [Pete] hit the flash button. No dice. Investigation with some terminal software indicated a checksum error.
Assuming the board was dead, [Pete] grabbed another — and suffered the same problem. The WEMOS boards wouldn’t program, but other boards had no issues. Sensing that something may be amiss, further research was in order. A forum post turned up discussing different programming modes for the ESP8266.
It turns out that there are different types of flash used …read more

I work for a company that sells USB memory. Recently we’re getting more and more complaints about files disappearing from the thumbdrives or not being able to write files to them.
I test all flash memory under Linux with f3 … Continue reading Bad USB flash drive, f3 tests passed fine, what could be wrong? [on hold]
Finally, Adobe is Killing FLASH — the software that helped make the Internet a better place with slick graphics, animation, games and applications and bring online video to the masses, but it has been hated for years by people and developers over its buggy nature.
But the end of an era for Adobe Flash is near. Adobe announced Tuesday that the company would stop providing updates and stop

You may still have some luck getting those selfies off of your SD card, even if it will no longer mount on your computer. [HDD Recovery Services] shows us a process to directly access the NAND memory of a faulty micro SD card to recover those precious files you thought about backing up but never got around to.
On a Micro SD card you may have noticed there are two slightly longer pins than the rest. These are VSS and VCC pins. As long as they are not a dead short between the two the SD card controller isn’t completely …read more

When [sticilface] started using the Arduino IDE to program an ESP8266, he found he was running out of RAM quickly. The culprit? Strings. That’s not surprising. Strings can be long and many strings like prompts and the like don’t ever change. There is a way to tell the compiler you’d like to store data that won’t change in program storage instead of RAM. They still eat up memory, of course, but you have a lot more program storage than you do RAM on a typical device. He posted his results on a Gist.
On the face of it, it is …read more
I have just been passed some data in a thumb drive (which I was expecting). While I’m not too sure exactly what format the data will be in, it should be a mixture of numbers and text, possibly in one of the Microsoft office d… Continue reading Securely obtain information from a USB Flash Drive /Thumb Drive avoiding viruses

Secure data deletion is known to be more complicated and elusive on a solid-state drive than for a regular hard drive. For instance, the logical block mapping on the SSD’s flash translation layer makes it impossible to reliab… Continue reading Is there a real-world example of SSD data recovery?
