Water damage can be devastating to electronics. Valuable data stored on devices such as phones, laptops, and external drives can be lost in an instant when exposed to moisture. However, with the right approach, it is often possible to recover data from water-logged devices.
Evaluating a Water-Damaged Device
When attempting data recovery from a water-damaged device, the first step is to assess the extent of the damage. There are a few key things to look for:
Signs of Visible Damage
-
Corrosion – Are there signs of corrosion on the device’s electrical contacts or circuitry? This indicates mineral deposits were left behind as the water evaporated.
-
Residual Moisture – Is there evidence of remaining moisture inside the device? This makes data recovery efforts more challenging.
-
Cracked Casing – Did the water exposure crack open the outer casing? This exposes the sensitive internal components.
-
Burn Marks – Any evidence of electrical short circuits or burn marks point to severe water damage.
Functionality Tests
-
Does the device power on? Failing to power on suggests major damage.
-
Can you still access the storage? Being unable to detect the hard drive, memory card, etc. implies the storage components themselves have failed.
-
Do basic functions still work? Testing buttons, ports, and on-screen features helps gauge the water’s impact.
Drying Out a Wet Device
If a damaged device shows signs of remaining moisture, it is critical to dry it out before proceeding with data recovery. This reduces the risk of short circuits and corrosion growth during the recovery process.
Steps to Dry a Wet Device:
-
Remove power sources – Detach batteries, cables, chargers, or any other power sources.
-
Disassemble – Take the device apart to expose internal components to air.
-
Dry with airflow – Use a fan or airflow from a hairdryer (cool setting) to facilitate drying.
-
Absorb moisture – Place device in a sealed container with silica gel packs, which absorb moisture.
-
Give it time – Allow at least 24-48 hours for thorough drying before reconnecting power.
Data Recovery Methods
Once the device is dry, the next step is attempting data recovery. The best approach depends on the type of damage and whether internal storage is still accessible:
Recovering Data from Functional Storage
If the storage drive itself still works, the data may be recoverable even if the rest of the device is damaged. Connect the drive to another computer and try to access the files.
This works best for external drives with standard connections like USB. For drives or memory cards removed from damaged devices, use a compatible external dock or adapter to connect to a working computer.
Professional Data Recovery Services
For severely damaged devices, professional data recovery is often the only option. Reputable services have specialized tools to extract data from corrupted drives.
This is often needed for phones, tablets, laptops, and other devices with proprietary storage that can’t simply be removed and accessed externally. The cost for professional recovery ranges from $300 to over $1000.
Repairing the Original Device
In some cases, fixing the original damaged device may enable accessing the data stored on it. For example, replacing phone screen or laptop keyboard that was affected by water. This avoids the need to recover the data itself separately.
Preventing Data Loss from Future Water Damage
While data recovery is often possible, it is always better to avoid water damage in the first place. Some key precautions to take:
-
Keep devices away from bodies of water and liquid containers.
-
Never charge devices near a water source, such as beside a bathroom sink.
-
Use waterproof cases or dry bags when bringing devices near water.
-
Enable automatic photo backup services to cloud storage for phones and cameras.
-
Maintain backups of important data from other devices.
With proper precautions, you can prevent finds yourself needing these data recovery tactics. But if your device does take an unfortunate dunk or spill, don’t panic! Just take the right steps immediately and there is a good chance your data can be rescued.
