I have a working hard drive (Barracuda 7200.7) from a 2007 HP Pavilion a430n that contains files that I would like to retrieve.
Your description has me confused. I'm not clear on which power and data cables you are using. You described pulling one cable from first hard drive and connecting it to your second drive. Extra power connections should have been in a loose wire bundle somewhere in the computer. (Often they are tucked into an unused drive bay.)
The SR1720NX has 2 SATA controllers and two IDE controllers. Thus it can have 2 SATA and 4 IDE devices. The computer sometimes shipped with a SATA hard drive or an IDE hard drive. In all cases, the hard drives must be connected to the data cable (and to the motherboard) and then the power connection from the power supply has to be connected. So there should be 2 cables plugged into each drive. The optical drive is usually an IDE drive for this model, also a master drive.
The IDE power connection is a large 4-pin Molex connector; the SATA power cables are a smaller 5 pin connector. There is also a small 4 pin connector that powers a floppy drive, if present. IDE data cables are a wide 40-pin ribbon cable (sometimes an 80-pin cable for master/slave). The SATA data cable is a 15 pin cable.
First make sure that the jumper on the drive from the A430n is across the two pins in the second position (counting from the side away from the power connection). This is the cable select option. Next make sure that the IDE cable is firmly connected to both drives and the motherboard. (I've sometimes loosened the data cable while connecting the drives.) Finally check that the appropriate power cables are firmly connected to all the drives. Then power up the computer. (With the second drive on the Slave connection, if the device on the Master connection isn't powered up/recognized, then weird things may occur.)
BTW: you should be alert to the power needs for the computer. The original power supply could be overloaded with the extra drive. You might be better off using an external drive enclosure (USB) or a USB/SATA/IDE dongle that leaves the drive out in the open. Connect these with extreme care following the directions for when to connect the power supply. Some enclosures won't work without reformatting the drive - you do not want one of those.
I hope this helps.

this is NOT the primary as mentioned above. it isn't receiving power. i tesed the molex connectors on my tower, as well as a few others. they work but not my HDD
HDS728080PLAT20 DOES NOT READ INTERNAL BURNERS
Same model, when i connect it and turn on the power it takes 2 seconds and everything turns off (the whole cpu), I tested the power of the tower and works fine (everything works but the HD).
My guess is the controller board is not working so if i look close at the "infineon" chip i found out a little circle that i don't know if it has been there always or if that's the problem. (the circle is on the bottom right if you look at the chip on the proper way to read it)
