Just can't mount that SD card?

Hack a Day have posted a quick quide on how you can recover data from an unmountable SD card in a safe and fairly easy manner.  With the use of sandpaper, solder and enamelled wire you can hook up the VSS and VCC pins to a NAND reader, as long as there is a working controller on the card and no physical shorts.  If you don't happen to have a NAND reader, they link to a project that will show you how to build your own, or you can source it from a supplier.  Once you have read the data you can flash it to another SD card or learn about how to translate the content if you have the tools.  Check out the comments for more and keep an eye out for a follow up article on working with the recovered data.

"If you ever find yourself in need of an SD card recovery tool you could always roll your own DIY NAND reader. We will likely give this process a try just to play round with the concept. Hopefully we’ll never need to do SD card recovery!"

SDXC SD cards come at a big premium; too bad we can't slide an M.2 SSD into our cameras

You may recall a while back Allyn put together an article detailing the new types of SD cards hitting the market which will support 4K recording in cameras.  Modders Inc just wrapped up a review of one of these cards, Patriot's 256GB LX Series SDXC card with an included adapter for those who need it.  The price certainly implies it is new technology, $200 for 256GB of storage is enough to make anyone pause, so the question becomes why one would pay such a premium. Their benchmarks offer insight into this, with 83Mb/s write and 96Mb/s read in both ATTO and CrystalDisk proving that this is a far cry from the performance of older SD cards and worthy of that brand new ultra high definition camera you just picked up.  Lets us hope the prices plummet as they did with the previous generations of cards.

"Much like Mary Poppins bag of wonders, Patriot too has a method of fitting a substantial amount of goodness in a small space with the release of their 256GB LX Series SDXC class 10 memory card. Featuring an impressive 256GB of storage and boasting this as an “ultra high speed” card for QHD video production and high resolution photos."

SanDisk Launches 512GB SDXC Card for $799.99

Assuming your camera, card reader, or other device fully conforms to the SDXC standard, Sandisk has developed a half-terabyte (512GB) memory card. Beyond being gigantic, it can be read at up to 95 MB/s and written at up to 90 MB/s, which should be enough to stream 4K video. Sandisk claims that it is temperature proof, shock proof, water proof, and x-ray proof. It also comes with a lifetime warranty and "RescuePRO Deluxe" recovery software but, honestly, I expect people would just use PhotoRec or something.

It should be noted that the SDXC standard covers memory cards up to 2TB so it will probably not be too long before we see another standard get ratified. What is next? SDUC? SDYC? SDALLTHEC? Blah! This is why IEEE assigns names sequentially.

The SanDisk Extreme PRO UHS-I SDHC/SDXC 512GB memory card should be available now, although I cannot yet find them online, for $799.99 MSRP.

Toshiba's FlashAir Class10 is a Wi-Fi enabled SD Card which thankfully supports a number of security protocols which should make it easy for you to get pictures from your camera without sharing them with the world. Madshrimps like the bundled FlashAir software which allows you to tweak functionality up to and including setting up Internet Pass Thru Mode.  Check out the surprisingly fast transfer rates in their full review.

"The FlashAir Wi-Fi SDHC from Toshiba is available in different capacities of 8GB, 16GB or 32GB, features a well-developed interface for easy access from both our PC and mobile devices without the need of using an extra app and is also built with the Internet Pass Thru functionality for being able to browse the web while being connected to the newly connected network."

Bring dead data on an SD card back to life with the power of Arduino

It would seem that there is more than one way to access an SD Card, and the usual interface used by your devices called SDIO can be the failure point preventing you from accessing your data.  The alternative method is called SPI mode which is significantly slower but also less complex which means that when SDIO fails you may still be able to access and copy your data using SPI mode.  Over at Hack a Day you can read about how to use a Playduino One Arduino clone and a SD card shield along with some custom Python scripts to recover those vacation snaps.

"A few days ago, one of [Severin]‘s SD cards died on him, Instead of trashing the card, he decided to investigate what was actually wrong with the card and ended up recovering most of the data using an Arduino and an immense amount of cleverness."
