What Is an SD Card?
Through collaborative development, SanDisk, Toshiba, and Panasonic invented SD cards in 1999. Secure Digital (SD) cards are proprietary non-volatile memory regulated by the SD Association. The SD Association is a non-profit initiative to create and maintain industry-wide standards for SD cards.
In general, memory cards are thin, light data storage devices. Their particular form factor makes them ideal as removable storage for small devices. You can pop a memory card into your camera, take enough pictures to fill it up, and then pop the card out, empty out its contents, and slip it back in.
An SD card might just look like one giant chip to a layperson, but the outside is actually a shell. Crack open the shell, and you’ll see something very similar to the inside of a typical USB flash drive. You will find one or more flash memory chips, along with a controller chip soldered to a printed circuit board. The NAND flash memory chip stores all of your data. When you plug your SD card into your computer, camera, or another device, data flows to and from the memory chip, organized and regulated by the controller chip. The controller keeps track of any bad blocks on the NAND chip as one of its many duties.
Many SD cards, however, along with their smaller cousins microSD cards, have a “monolithic” construction. All of their components are soldered together and extremely challenging to access if the device no longer functions. Gillware’s incredible research and development efforts have given us the tools and methods to recover data from these devices.
How do SD Cards Fail?
Generally, SD cards and microSD cards are a bit less vulnerable to physical damage than USB flash drives. In many USB flash drives, the USB plug has a frail connection to the PCB that can easily be damaged. Since an SD card’s electrical contacts are built into the PCB, that is one less point of failure. Also, SD cards are usually tucked away very discretely in their devices, so it’s hard for them to be accidentally broken while in use.
But while an SD card can survive a fall that would kill a hard disk drive, it might not fare so well if it gets stepped on, driven over, etc. This could crack the PCB, or even the NAND chip itself. A cracked NAND chip is roughly equivalent to a hard drive platter with rotational scoring: It’s toast.
An SD card can also fail as a result of a power surge. It only takes a surge of three nanoseconds to short out a PCB. If an SD card is plugged into a device when power surge occurs, the PCB can be shorted out. This traps all of the data on the NAND chip with no way for anyone outside of an advanced data recovery lab to retrieve it.

What’s the Difference Between SD Cards and microSD Cards?
The difference between SD and microSD cards is mainly a difference in size. That’s size as in physical size, not capacity, as manufacturers are starting to cram a whopping 256 GB and more into microSD cards. Mainly, microSD cards can comfortably fit on one of your fingernails if you are an average-sized person, and regular SD cards cannot comfortably fit on one of your fingernails unless you are a giant.
Recovering data from SD cards and microSD cards tend to follow mostly similar processes, depending on the design of the SD card. All microSD cards use monolithic chip designs and most SD cards now use the same monolithic chip design as their tinier counterparts. In other words, there’s no real structural difference between most SD and microSD cards. The difference between the two is about as negligible as the difference between a 3.5″ hard disk drive and a 2.5″ drive. The way they store data and the ways they can break down and fail are more or less exactly the same, as are the methods Gillware’s specialists need to use to get your data back from them.
What Are Common SD Card Data Loss Situations?
Logical failures in SD cards are more common than physical failures. Like most removable storage media, SD cards aren’t supposed to be removed while in use, or without being safely ejected.
Removing an SD card without warning can result in file corruption or corruption of the partition table or boot sector. A corrupted boot sector or partition table will make an SD card appear to be blank. Files can also be deleted from an SD card, or the card can be accidentally reformatted.
Taking a Deeper Look at SD Card Corruption
Have you noticed that your Windows, Mac, or Linux laptop / desktop gives you the option to ‘eject’ storage mediums? It is strongly recommended that you eject storage devices before removing them from your computer because ejecting the device suspends read / write operations. SD card corruption often occurs when data is being written to the SD card and the card is removed abruptly. In many cases this will impact the storage medium as a whole, rather than only the data that is in transmission.
SD Card Filesystems
SD cards typically come out of the factory with FAT16 or FAT32 filesystems. Unlike proprietary Mac, Windows, and Linux systems, FAT filesystems play nicely with just about everyone. A user can reformat their SD card with any other filesystem. Different filesystems have different features, so messing with an SD card’s filesystem can provide some benefits. However, this can decrease the performance or lifespan of an SD card.
Many of the controller chip’s error correction and wear leveling techniques are based on the assumption that the card is formatted with a FAT filesystem. Replacing the filesystem can lead an otherwise-healthy SD card to die before its time.
The most typical situations involving SD card data loss include:
Prompts for initialisation/reformat
Card does nothing when plugged in
Can SD Card Recovery Software Help Me?
SD card data recovery software can sometimes recover files that you have accidentally deleted or lost to an accidental reformat, as long as you use it carefully. But the NAND flash memory chip that makes up your SD or microSD card works very differently from most storage media, even if it doesn’t look like it. Sometimes data that has been deleted or erased by a reformat will appear to have completely disappeared according to any data recovery software tool you try. However, the data is still there–it’s merely been hidden by a quirk of flash memory data storage. Advanced forensic data recovery software can dig it up again.
Wondering about the costs of recovering data from SD/microSD cards?
The SD/MicroSD Card Data Recovery Process
Since so many of the common ways SD cards fail are logical, SD card recovery tends to play by many of the same rules as logical recovery from other devices. Regardless of the differences between the underlying hardware, recovering data from an accidentally reformatted hard drive and SD card follows roughly the same process.
Whenever you delete data from, accidentally reformat, or corrupt the boot sector of something, you are only making a small change to its filesystem. Deleting a file doesn’t automatically erase it, but rather marks the space taken up by it as “unused”. Reformatting does this on a larger scale, but can also partially or completely erase the old filesystem architecture. And it only takes a single corrupt sector to make an SD card seem to be blank.
Even though these changes are small, they have big consequences. It is the job of our SD card recovery service technicians to use our specialized data recovery tools and techniques and go where you cannot. We use HOMBRE, a proprietary software designed for and by our data recovery experts, to investigate these changes to the filesystem and salvage the data from your failed SD or microSD card.
In the event that your SD card’s PCB is damaged, our engineers must gain direct access to the NAND chip and piece its contents back together, bypassing the failed PCB and controller. This can involve removing the NAND chip and connecting it to a chip reader, or in the case of microSD cards, soldering tiny wires to specific contact points on the device.
