Portable computer memory has become increasingly used in mobile devices, such as cell phones, media players, cameras and GPS devices, over the years. One of the smallest physical units for storing data is a micro SD card, which is about the size of a human fingernail. Because of their small size, these cards are susceptible to damage. Therefore, protecting them requires some care and effort.

To reduce the possibility of damage, handle the card over a counter or table when transferring it from one device to another, preventing it from falling all the way to the floor if you drop it.

Use a protective case for the card whenever it's not in use. Hard plastic covers provide an extra layer of protection against both impact damage and moisture penetration.

Keep the card stored inside its designated device, such as a cell phone or media player, as much as possible. Although the device is likely to suffer damage if dropped, its hard exterior will help shield the SD card against damage. The card is much more vulnerable when stored outside of the device.

Write-protect the data on a micro SD card by inserting it into a card adaptor and sliding the locking switch on the side of the adaptor into place with your fingernail. This prevents the data on the card from being deleted or overwritten. The other advantage of the adaptor is it enables the micro SD card to fit in the larger card slot. There are two sizes of slots---one being the micro SD size; the other being standard. The adaptor allows you to fit the micro SD card into the standard slot.
