My friend has a pretty ancient computer,till tomorrow he had Seagate 80gb HDD.It encorporated Ultra DMA connection (not SATA).
While I gave my own HDD,for Storage,I saw the drive connected to that UltraDMA or serial-ish port(or whatever it is called) and beside that there was an interface for power connector.I figured it was a 4 pin molex-power connector.
The problem began when I connected my HDD and tried to connect his own.The problem is as follows.
1.There is that Old Ultra-DMA port and beside that a molex power connector.
Should I connect both of them?or is Ultra-DMA enough.Before removing old HDD and Installing new one I didn't see both of them connected.Or I'm not sure.However.
2.If I only connected Ultra-DMA and not the 4-pin power cable,the HDD is not recognized
3.If I connected both,then the system won't boot up.The motherboard starts and shuts itself down.
I thought it was maybe due to power supply,not able to power HDD through the connector.But it wasn't.

The major problem is,I didn't see how it connected before (1 or both),and while tried the above methods none worked.Are the implications that the HDD is dead?.If so,please confirm,if not give the solution and You're welcome.
P.S -Sorry for such a boring description!

The two connectors on the back of a non-SATA hard drive are the IDE port & the 4-pin power connector.
Both must be connected to the appropriate cables in order for the drive to be recognised and for it to work.

In addition, the jumper at the back of the drive must be set it in the correct position for either "Master" or "Slave", depending on which connector it is attached to on the IDE ribbon cable.

If all that is done correctly and the drive doesn't work or system won't boot, the drive has most likely failed.

Thanks.If I connect both of them,the system won't boot.The computer starts,but everything shuts down after 3 seconds.Is it the symptom of a dead HDD.Since I don't think it's dead.Atleast it should have got into BIOS.

Yes, I would say the drive has failed, or the "Master" or "Slave" jumper is set incorrectly on the back of the drive.
Is the drive connected to the end-connector or the middle-connector of the IDE ribbon cable?

Yes there are 2 connectors on the same IDE-ribbon.And it is connected to the end connector.

Then the the drive's jumper should be set to the "Master" position (denoted by the letters MA on the drive casing).
If there's a another drive or cd-rom connected to the middle-connector, make sure it's jumper is set to Slave (SL)

The CD-ROM Drive is separately connected to other IDE-Port.I think it is master IDE,but I'll check that again and confirm.Anyways, thanks for your help Philip.

Note - master/slave settings on an IDE drive have nothing to do with which connector is used; both connectors are identical. If you have just one IDE device then it must be set to "master". If you have two then one must be "master" and one "slave". This affects the drive numbers the BIOS gives the drives.

So, set the drive to be master and connect it to either IDE connector. Connect a molex power plug also. If it then won't boot it is not a bootable drive.

How come it isn't bootable drive it had been in use for 8 years.And the moment I plug the power cable the computer shuts down.Now if I want to turn on,I can't I have to switch off the PSU switch and then on,so that I can try one more time.This is weirdest paradox that I have come across.The IDE is in Master mode and then nothing happens,no matter which connector is connected!.
Atleast if the Drive has failed it would post something or the BIOS post would be visisble.But nothing,as if the whole Computer is shorted,it shuts down.

Weird for sure, difficult to diagnose without actually being there to take a look, since, with all due respect, it's apparent you're not exactly up to speed where the innards of a PC are concerned.

As regards the drive itself, 8 years is a pretty good lifespan as hard drives go, certainly longer than the average, so you shouldn't be surprised if it has failed after all those years of use.

I wouldn't have expected it to interfere with the PC POSTing though, I've never known that, and I can't help with something I've never experienced, I won't pretend to know and give you a load of bulls**t.

another option would be to use a ide to usb converter;
http://www.amazon.com/USB-Cable-Adapter-2-5-Inch-3-5-In...
1. boot the system with healthy drive.
2. connect the power connector and usb converted to the drive you are trying to connect donot plug the usb cable into the pc unless windows or OS is fully loaded and ready, once ready connect the usb cable and see if it helps.

totally agree with philips, its quite a good lifespan for a hard drive, its most like failed or has some issues.

good luck.
