I have an older 3.5 HDD enclosure that uses a 5 pin serial power plug. When the power adapter wasn't working well anymore (it started making loud ticking noises), I purchased a new one off ebay.
I just got it now, plugged it into the power socket and the little green light appears on the power adapter but as soon as I plug the 5 pin serial into my external HDD, the green light goes off and the HDD has no power to turn on.
I noticed the specs on both the original power adapter and the new one I got. It appears all to be the same except one part: the new one says 0.85A max and the original one has 1A. Is that the reason why the new power adapter doesn't provide any power to my external HDD?
Here are the exact specs of both: the left one is the new power adapter, the right is the original that no longer is working.
