Protect hard drives from extreme temperatures
External hard drives are allowed on planes, both in carry-on and checked luggage. Airport X-ray scanners do not have any magnetic properties, so you do not have to worry about damaging your drive or losing data due to a magnetic field. Therefore, airport X-ray machines or any kind of X-rays, for that matter, won't damage your hard drive.
However, hard drives are sensitive to extreme temperatures, especially when they are in use. To protect your hard drive from extreme temperatures, follow these steps:
- Avoid exposing your hard drive to extreme temperatures. Keep your hard drive in a cool, dry place.
- If you are travelling to a place with extreme climates, consider investing in enterprise hard drives that can handle extreme temperatures.
- If you are moving your hard drive from a cold environment to a warm one, let your drive slowly acclimate to the ambient temperature by keeping it in its transport box or bag. This will prevent condensation from forming inside the drive, which can damage your data.
- If you are storing your hard drive, keep it in a waterproof box to protect it from extreme temperatures.
- If you are using your hard drive in a hot environment, such as a freezer, consider installing additional case fans to blow cool air at your hard drive.
