Double hDD's

Ok so i have 2 Seagate 500gb hdd's both bought at the same time. both identical with similar serial numbers. i can plug one in and it shows on my computer however when i plug the other one in while the 1st is still in it doesn't recognize it's there. why is that and can do something about it. i named them both differently and plug them into separate ports on both sides of the laptop soooo...

What type of connection to the mobo are the drives using? What are the maximum connections on the mobo for your drives? Assuming that these are connected using sata, there could be a set limit and to get by this you must turn on AHCI mode for the mobo to recognize the rest of the drives. This would require a reinstall of the OS and installing the AHCI driver from with in the BIOS.

4 connections 2 on each side. damn i just reinstalled my OS to give it a clean up i ain't gonna do this for a while. it doesn't matter it really isn't that important to have each one i was just wondering. but it's always good for the knowlege so how do i go about doing that

What does "4 connections 2 on each side" describe?

When you boot the computer, enter the BIOS set up and see if both drives are listed and post back.

What model drives and mobo?

Many times you will have to enable sata connectors in the bios. I suspect that you've plugged the drive into an un-enabled sata connector that just needs to be turned on........the story of my life ! lol

You still haven't said if they are eSATA or usb 2.0 or USB 3.0. also, fill out your system specs. If you are saying 2 on each side, it seems you are talking about a laptop. Not many laptops have 2 eSATA connections. And for the Seagates to work they need to be USB/eSATA combo drives.
