I will find the first out tomorrow, but it looks like a standard hard drive.
Gigabyte MA770t-UD3P motherboard.
One sngle 1TB hard drive.
Almost all 1TB drives are SATA, but you can look at the connectors on the drive to make sure.
IDE (PATA) will have a large box-shaped 40-pin connector, about 2 in. (5 cm) wide.
SATA will have two much smaller connectors, one 15-pin (power) and one 7-pin (data).
http://www.xbitlabs.com/images/mainboards/gigabyte-ma770t-ud3p/board-1.jpg. It has a single IDE connector (the green box-shaped one at lower left) and six SATA connectors (the yellow lozenge-shaped ones just above and to the left of the IDE connector).
The mounting instructions depend to an extent on your case. If your case has a "tool-free" mounting design, you slide the drive into place and close the latch. If your case has screw mounts, you slide the drive into place until the threaded holes on the drive line up with the matching holes in the drive cage. Then you fasten it in with the (hopefully provided) screws. There will be screw holes on both sides of the drive; you need to remove both side panels of the case to get to them.
Connecting the cables depends on whether you have a SATA or IDE (PATA) drive. For SATA, it's easy: plug a matching connector from the power supply into the drive's power connector, and run a data cable from the next SATA connector (the first one is numbered SATA_0, the second is SATA_1, etc., as printed on the motherboard) to the drive's data connector.
If you have a PATA (IDE) drive, it depends on whether you already have a PATA drive (usually a DVD or CD drive) connected. The remaining instructions are for the (unlikely) case where you got a new PATA drive; if yours is SATA, ignore this.
If you don't, then review the jumper setting on your drive. These are usually on the rear of the drive, by the power and IDE connectors. There are three (sometimes more) positions; the important ones are labeled Master, Slave, and CS (Cable Select). Set the jumper to Master. Plug one end of your IDE cable into the motherboard (if your IDE cable is color-coded, it will be the blue connector) and the other end into the drive.
If you do have a drive already connected, review the jumper settings on both the new drive and the one that's already connected. You must set them to either:
* One set to Master (usually the one that's there already), one set to Slave (usually the new one).
* Both set to CS (Cable Select).
Once you have the PATA drives jumpered, plug the remaining connector of the IDE cable into the drive.
Connect one of the 4-pin connectors from the power supply to the PATA drive.
Before putting the covers back on, boot and press DEL (or F2, or whatever's required on your computer) to enter the BIOS. Make sure the BIOS "sees" all your drives. If it doesn't, go back and make sure everything is plugged in: data and power connectors on both drives. If you have a PATA drive, make sure the jumpers are set correctly (Master, for a single drive; either one Master and one Slave, or both Cable Select for two drives). In the BIOS, make sure that you haven't disabled any of the SATA or IDE ports.
Once all your drives are recognized, boot into Windows, and go to your Control Panel->Administrative Tools->Computer Management. Open Disk Management, find the new drive, format it, and give it a drive letter. You're good to go.
