Own A Laptop? Make A Thumb Drive Theft Alarm With Free Tool

Turn An Old Thumb Drive Into An Anti-Theft Device

Prevent the theft of your laptop. Laptop theft is common and a constant threat. There is a free program – LAlarm – which when installed emits a loud siren sound when a thief tries to steal your laptop. And it can destroy selected data (and recover it later) if the laptop is stolen; which is an important step in protecting your “identity”, and personal information.

LAlarm consists of five alarms and other security functions designed to protect laptops and sensitive data.


  • Theft Alarm- It prevents laptop theft by sounding an alarm when a thief tries to steal a laptop.
  • Perimeter Alarm- It alerts when a laptop goes outside a perimeter.
  • Data Destruction- It protects sensitive data by destroying the data if the laptop is stolen.
  • Data Recovery- It can recover data from a stolen laptop.
  • Mobile Phone Alert- It sends an alert to a mobile phone via email or SMS.
  • Theft Response- you can tell your laptop what to do in advance if your laptop is in hands of a thief.

What I found “kewel” was the feature that lets you use an old thumb drive as a “sensor” – as described here, fasten a laptop to a table by using a USB flash drive strap. When a thief removes the laptop from the table, the flash drive will be disconnected from the laptop and then an alarm will go off.
A great use for that old 128 MB thumb drive sitting neglected in a drawer..!

If you “go mobile” with your laptop, I highly recommend you take a look at this free program. To do so, click here.

  1. TechPaul,

    I have been seeing this and never gave it a try. Thanks for explaining it features and that it actually does do what it says it does. I will be putting this on my “to review” list. I can see where this would be helpful to laptop owners, especially Students…

      I only did limited testing of LAlarm. I did not test all of the features (I didn’t delete/recover data, for example). But I can tell you it installed and uninstalled properly on a XP Pro and a Vista Home Premium machine, and that the computers made loud noises when the thumb drive was pulled.

      I agree that this would be great for students, as well as “road warriors”.

      It is not an end-all-be-all theft preventative (as there is no such thing..) but it is a nice theft deterrent, if used consistently and conscientiously.
