External HDD with enclosure question

Hi all,

Iím replacing my current AC adapter for the external hard drive with enclosure with a new one. Here are the specs of the current one.
Input:100-240v 50-60Hz 1.2A
Output:5v=2A 12v=1.2A

The one Iím considering buying an adapter which has the following specs:
Input:100-240VAC 50-60Hz 1A
Output:12V=2A 5V=2A

Are these 2 adapters compatible in terms of Voltage and Ampere please. Will it work with my external HDD with enclosure? Thanks for your time.

Just make sure the positive/negative connections going from the adapter to the enclosure are the same or you could possibly fry it trying to push power through the system in reverse. They'll probably be the same but it can't really hurt to check. There should be an indicator on the plug that looks like this:
