Users of certain I-O Data network hard drives may want to take notice if they're worried about keeping their data (and themselves) safe, as it seems that a couple of the AC adapters used with them have the unfortunate tendency to overheat and melt, posing a potential burn hazard to consumers. The adapters affected all have the model number IO-ACADP1510UL, and were sold with UHDL-160U and UHDL-300U model hard drives between December 2004 and February 2007. That apparently totals a whopping 740 adapters, a number we're guessing I-O Data would otherwise rather keep to itself. While there hasn't been any injuries reported, the Consumer Product Safety Commission is advising users to immediately stop using the adapters and contact I-O Data for a free replacement. If that includes you, you can click on through for all the necessary information.
