How to Dry Out a Flash Drive Dropped in Water

By Gareth Downes-Powell

As flash drives are so small, they are easy to put in a pocket and forget about, which can lead to an inadvertent trip to the laundry. Most flash drives will survive a trip through the washer, as they are usually well sealed and have no battery. It is important not to use the drive if any moisture is present, but once dried the drive should still be useable with the original data intact. All that is required to save a wet flash drive is a bowl of uncooked rice.

Things You'll Need

  • Paper towel
  • Uncooked rice
  • Small flat-blade screwdriver
  • Sealable plastic bag

Step 1

Dry the flash drive as much as possible with a piece of paper towel to absorb excess moisture.

Step 2

Gently pry open the case of the flash drive if possible, using a small flat-blade screwdriver to separate the two halves of the case. This is not essential, but will cut the drying time and will help to limit corrosion. Dry the inside of the case as much as possible with the paper towel.

Step 3

Pour some uncooked rice into a small plastic bag, and then place the flash drive in the bag and seal. Place the bag in a warm, dry place for at least 24-hours. The rice draws out and absorbs any moisture present, speeding up the drying time and ensuring the drive is completely dry.

Step 4

Check the drive after 24 hours. If you can see any moisture, leave the board for 24 hours and repeat until the board is completely dry.

Step 5

Reassemble the case, ensuring the two halves are tight shut. Use a small spot of glue to hold the two halves together securely if necessary. You can then use the flash drive as normal.
