Re: optiplex 745. Want to add second sata drive. Put in...
Go into CMOS to check that your sata ports are enabled.If not, then enable them and make sure you save the settings on exit from CMOS. Make sure your SATA drive cable and the drive power cable is attached correctly to both the drive and the motherboard. Reboot the pc and the system POST (power on self test) should see all of the attached hardware including the ide and sata drives. Depnding on which port you have plugged the sata drive into it will appear as sata1 sata2 sata3 or sata4

Installing windows 7 isn't difficult. First, you need the disk to install it from. If you don't have that, Microsoft no longer sells this version, so it will be harder.
If you want to keep your programs and data, there is a package, "PC Mover" that you can buy that will help you preserve all your data and programs. I've used this many times to help upgrade systems like yours.
If you want to create a new Basic Input/Output System (BIOS) password on a Dell Optiplex 745, reset the password. Resetting the password also applies if you want to remove an existing BIOS password. BIOS passwords are used to add an additional level of security to your machine. Without the correct BIOS password, your Dell Optiplex 745 will not complete the boot process. The password can be reset whether you know your current password or not.
Turn off your Dell Optiplex 745. Start the computer. Press "F2" the moment the Dell logo appears on the screen. You will only have two to three seconds to press the key. Enter your BIOS password. Navigate to the "Exit" screen. Select the "BIOS Password" setting. Enter your BIOS password and a new password if desired. Do not enter anything in the "New Password" box if you want to remove the BIOS password completely. Press "Enter" to save your password settings. Reset Forgotten Passwords Turn off your Dell Optiplex 745 and remove the power cord from the computer. Disconnect any external hardware and cables. Slide the release latch located on the back of your Optiplex 745. Lift the cover as you slide the latch. Hold the cover firmly and pivot it back on the hinges. Remove the cover from the hinges. Find the "PSWD" jumper on the motherboard. This is a two-pin jumper and should be clearly labeled. Use a flashlight and magnifying glass if you have trouble locating it. Remove the jumper from the motherboard. Replace the cover and slide it into place until the latch snaps into place. Reconnect the power cable and restart your computer. Shut down the computer after it has completely restarted. Disconnect all cables and remove the cover again. Replace the PSWD jumper. Replace the cover. Reconnect all cables and restart your computer. b> Clearing forgotten passwords http://phubner.eng.ua.edu/Files/Optiplex 745/advfeat.htm - wp1117484
With sata there are two cables, just like ide. One is the power and the other is for data. The data cable goes from the device to the motherboard. The power comes from the power supply. If your power supply does not have a sata connection you can purchase an adapter that will turn an available 4pin Molex into a sata connection.
Unlike IDE drive cables, which allow you to connect at least 2 drives to the same cable, SATA cables only allow one connection from motherboard to drive per cable. You can connect as many SATA drives to your motherboard as you have SATA connections.
Yes you can. If you are adding a second hard drive, don't forget that you will need to purchase an additional SATA cable. If you are replacing your current hard drive, you shouldn't need any additional cables.
Download the hard disk drive's manufactures tools software to setup your SATA drive. Make sure the bios see's your 1TB drive listed. If it is going to run your operating system check the Boot section in your bios & make sure it is listed in the boot order.
Make sure its jumper is set as slave, if you have a 40wire ribbon cable, and cable select if you are using a 80 wire ribbon cable, if it is on the same ribbon cable.
If it is on the second ide cable, by itself keep it as master.
Update: SATA II drives do have jumpers to make them backwards compatible with 1.5 Gb/s (SATA II drives are 3.0 Gb/s). So if your system is older and can only handle SATA (first Gen) then you have to add a jumper (Seagate has the jumper setting on the drive but sometimes supplies no jumper i.e. you have to have your own).
