You can find it in not only your SD cards, but in your flash drives , SSDs , smartphones , and tablets as well. Platters are divided up into tiny magnetically-charged regions. Each region represents a single bit of data. A NAND chip, on the other hand, is built out of cells. These cells are lined up in columns and arranged in rows across the chip.
Just like hard drive platters, NAND chips have a life expectancy. Over time and with use, the magnetic fields on parts of the platters weaken and decay, resulting in sectors going bad. The same aging process also affects NAND chips. Every time a cell is altered, it takes up a single program-erase cycle. Each cell is designed to last for hundreds of thousands of program-erase cycles or more. Solid-state devices have means of dealing with bad cells, just as hard drives have means of dealing with bad sectors.
Hard drives and solid state devices like SD cards can both identify failing sectors or cells and sweep them under the rug. But sometimes a failure catches the device by surprise. In this SD card file recovery case, some of the bad cells in the SD card were enough to cripple the device. Bad cells can crop up anywhere and have a variety of effects. In many cases, the cells can be in the middle of a file. The cells can also affect the boot sectors or partition table of a storage device, or cause firmware failure.
Bad sectors and cells are always a luck of the draw scenario. If they affect the wrong places, your memory card becomes a brick. Our secure online file viewer shows our client which files have been completely recovered and which have been incompletely recovered. The client can also see how much of each incomplete file has been recovered.

Upgrading your camera kit? Take a look at our pick of the best camera bags and cases. How to choose the best memory card Of course you will have a budget in mind and will also want to go for the highest capacity card with the quickest read and write speeds you can afford. The advice here used to be to opt for several cards rather than one giant capacity option, in case the latter became corrupted in some way and images lost. But, in truth, such occurrences are rare, especially these days. Aside from the most common SD and microSD cards, there still exists the older but at one time just as popular CompactFlash CF card, along with its successor in the newer XQD format, used by some of the most celebrated current mirrorless cameras, such as the Nikon Z6 and Z7.
