Bios not recognizing any hard drives

Well for IDE HDD's they should not only be set to CS {Cable Select} on the new HDD but also on the right type of IDE Lead.

The only time that I've seen anyone TRASH an IDE controller was when they plugged in a 2.5 to 3.5 inch adapter and plugged it onto the drive upside down and then connected it into the computer even then it only managed to take out one of the IDE channels as it had 12 VDC going into a Data line.

Shut down unplug the unit and leave it for a short time and then try again. Go into the BIOS and try to Auto Detect the fitted HDD's/CD/DVD Rom /s. If this doesn't work you may have to clear the BIOS by changing a jumper setting on one of the newer M'Boards or remove the battery on one of the older M'Boards. If it is the latter remember to make sure that the unit is unplugged so if the battery is dropped it will not destroy the M'Board.

Once you get it working with one IDE HDD installed you'll have to look at the jumper setting of the next drive that you wish to fit as there a re only two possible reasons that a HDD will not be detected one is if the jumpers are set wrong so the controller is seeing two drives and trying to work out which is which at the same location or the other and far less likely is that the Power Supply is not up to the job and just dies in the attempt to power the second HDD.

Really short of mixing up the 5 & 12 Volt leads to the HDD's it is virtually impossible to do any damage to either the HDD/s or the IDE controller.

But on some M'Boards they do need to be powered down before they will work again as a warm boot will not allow they to identify the HDD's.

Try the following (it has worked for me in the past.) Be sure to turn off and unplug the computer before connecting or disconnecting any cables inside the computer.
1. Open the case and remove all the drives. You don't need to physically remove them, but do remove the data cables from the drives. You do not need to remove their power cables if you leave the drives in place.
2. With the power cable still unplugged from the wall outlet, push the power button in, and hold it for 10 seconds, then release the power button, push it in again and hold it for 2 seconds and release it again.
3. Plug in and turn on the computer and set the CMOS to automatically detect all drives. The computer should not detect any drives since their data cables are not connected to them.
4. Check the jumper settings on each drive. Be sure each drive on a data cable are set as Master/Slave or as Cable Select. You MUST have both drives as Master/Slave or both as Cable Select.
5. Connect the Master drive on the Primary IDE cable only. If this drive's jumpers are different when configured as a single drive you may need to change the jumpers to configure it as a single drive (not necessary if you use cable select.) Then turn on the computer and see if the BIOS recognizes the drive. If this is not successful, you need to check the jumper settings on the drive and try again or replace the drive).
6. If you have a slave drive on the primary drive, be sure the master drive is set to Master (or Cable Select) then connect the secondary drive and power on the computer again. Confirm that both drives have been recognized. If either drive fails to be recognized check jumper settings and try again. Note that if one of the drives is defective you may need to repeat this from the beginning of my solution.
7. Repeat step 6 with the Secondary IDE.
This should help you resolve your drive problems.

It seems to be that the drives are set to Master which will cause the BIOS to not detect,you will need to look at the diagram on the drives
Locate the jumper on the back set one drive as Master,the set second drive as Slave,then connect this configuration to the primay IDE cable
Apply this to the second setup also,which would be Master/Slave on Secondary IDE cable
Hope this Helps
