I'm using a 3.5 sata hard drive enclosure. I've had it for about 4 or 5 years now, used it here and there. It seems that the ac power adapter is now dying. Even when it's plugged in and no loose connections, the green light that normally lights up on the rectangular box of the ac adapter doesn't light up. Sometimes a hard shake or hitting it turns it on and works after that. So I'm having to shake it around, hit it, smack on the floor gently to get the power flowing. Not sure if it's the actual rectangular box or the cord of the power adapter.
Where can I get a replacement power adapter? The end that goes into the HDD enclosure is a round circular plug (maybe 4 or 5mm?...it's not a big one like the ones found on laptops or netbooks but a bit smaller than that).
