I bought a Chinese SATA/IDE to USB converter that has no brand name. Specs for the power adapter are:
- Model: SY-002-5-12
- Input: 100-240 VAC, 50/60Hz, 0.8A
- Output: 12V and 5V both 2A
After connecting a 3.5" SATA HDD to my laptop via the converter, I sometimes get electric shocks from some parts of the laptop case.
The converter uses an AC adaptor with a cable like this:
That uses 4 wires for powering an HDD. Some say that it would be dangerous for HDD because of the lack of one wire.
Is it dangerous to use this converter? Why do I get electric shocks? Did I damage my laptop with this converter and small electric shocks?
EDIT: Now shortly after I'm writing this, the adapter made a spark/bang noise and went off. It doesn't turn on again. How can I tell if it damaged my laptop through adaptor > HDD> USB?
