I want to add a second hard drive to my desktop. I knew how to do it old my old IDE system but this is a SATA computer. I would like to add a 2 TB as a slave/secondary drive. I have Googled it and the physical part seems straightforward. Instructions I have found indicate that the drive (2nd) has to be set up in BIOS but doesn't mention just what I should do in BIOS. I have never messed with a BIOS before.

I would appreciate some guidance in this upgrade. Will this computer take a 2 TB or larger?

You don't need to do anything in the BIOS if you're just slaving the drive to the existing system for extra storage.

Power down the computer and unplug it from the wall.

Connect the extra drive to a spare SATA port.

Power on the computer.

Go into device manager and format the drive.

You'd need an available SATA connection on the motherboard as, unlike IDE, you can only have 1 SATA drive per cable. The bios will usually auto-detect an added drive but you may need to enable the controller in bios setup. Also, as a non-booting drive you wouldn't want it in the boot order. The manual for you system should give specific details on configuring the bios.

My guess is the bios on a computer capable of running windows 10 will see the drive OK but I haven't checked its specs.

I believe the SATA connectors are numbered in order beginning
with SATA 1, SATA 2, and so forth. However, a boot menu and
the BIOS will probably present you with something like Drive 0
and Drive 1 as the available drives if two drives are plugged in.
Drive 0 would be the same as SATA 1.

By default, the boot drive is whatever is plugged into SATA 1.

So you either need to make sure you plug the new drive into a
connector other than SATA 1, or tell the BIOS to boot from a
drive other than Drive 0.

If anyone understands this better than I do, please correct me!

Thanks for your quick responses. My new hard drive has been ordered and should be here around Monday. I will let you know how the install goes.

Please note that if you ordered the drive as an OEM drive (and possibly 'boxed' drives as well) you will need a new SATA3 cord (6GB/s) for the new drive since it probably will not come with one. You should have a spare SATA power connector on your power supply but on the chance you might not (check), you might need a 4pin Molex to SATA power adapter to connect it to the power supply.
@Jeff: I cannot vouch for all motherboard brands but the Gigabyte ones I have used are numbered SATA0 and up.
For a secondary drive is is always fine to try just plugging in the drive to any open SATA port and as long as the system boots up fine and does not complain then you do not need to access the BIOS. If however it it assumes that the new drive is bootable and gives you boot options or says that the drive does not contain a boot manager then access the BIOS and remove the new drive from the boot order and make it non-bootable. Then Save changes ans Exit to restart the machine. With a new drive you will need to access Disk Manager, create a new partition or partitions and format it/them to NTFS.

You have to be a little bit crazy to keep you from going insane.

My ASUS board has 6 regular SATA connectors numbered 1-6
plus two e-SATA connectors numbered 0 and 1.
