Your DVD drive only requires the power connector to be connected to it for it to be able to spin at least briefly when the computer is running and the button on the front of it is pressed to eject then insert the tray. It doesn't matter whether the IDE cable connector is backwards on a header on one header or what the jumper on the drive is set to in order to be able to do that.

The IDE cable connector must be inserted into the drive and the mboard IDE headers in the right direction if it's possible to insert it either way, and the jumper setting must be correct for it's situtaion in order for the drive to work properly in Windows and to be recognized by the mboard's bios, but pressing the button on the front of the drive should still work even if that's wrong.
E.g. when they're on the same data cable, one IDE drive must be set to Master, the other to Slave or both must be set to Cable Select (if it's the IDE hard drive you're booting an operating system from it should be on the END connector, not the middle connector, when both drives are set to CS so that it's seen as master). Some IDE hard drives, e.g. Western Digital models, have two ways they can be set to Master - Master, single, or similar, for when they are by themself on a data cable, or Master, with Slave, or similar, for when they are on the same data cable as another IDE drive that's set to Slave - that must be set correctly for the situation, otherwise the Slave drive may not work in Windows or be recognized by the mboard's bios.

However, if the IDE data cable is damaged it could be two or more wires shorting together in the data cable are causing your problem.
It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittant, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.

Try another data cable if in doubt.
.......

If there's nothing wrong with the IDE cable, the only thing I can think of that can cause the DVD drive to NOT spin at least briefly when the button on the front of it is pressed to eject then insert the tray is you have it connected to the same data cable as an old proprietary CD-rom drive that has a 40 pin header but it is not wired the same as for an IDE optical drive.
I did that by mistake once and an IDE hard drive on the same data cable did not spin when the proprietary Panasonic 2X CD-rom drive was connected to the same data cable.
.....

We HAVE seen a situation where some of the power connectors from the power supply have no +12v power, when the power supply has more than one +12v section - the DVD drive on a desktop computer requires both +12v and +5v power.

That's not enough description.
Does the drive still open and close and spin at least briefly when press the button on the front of it whem you have plugged in the IDE data cable connector ?
.
The only things that could be wrong is either the data cable is damaged or the DVD drive is defective.
Try a different IDE data cable !

" i did used 3 diff cable out of working machine and three different drives out of working machines"

3 different IDE data cables - good - but three different what drives ?
Hard drives ?
Optical drives ?

With the same problem DVD drive on the data cable ?
If yes, if the DVD drive won't spin in all cases when the IDE cable is connected, if you're SURE the jumper settings are right, the problem DVD drive IS defective and won't work with ANY computer.

(If you DO NOT have the jumper settings right, that's a different situation.
E.g. two drives on the same data cable cannot both be set to Slave or Master - both drives will not be detected by the bios.
Don't mix CS and Master/Slave jumper settings - some combos work, some DO NOT
The jumper settings for the same make of drive are not necessarily the same for all models.
The jumper settings of different makes of drives are often not the same
The jumper settings shown on a label on the top of the hard drive are sometimes upside down with respect to the back of the drive - if it shows the power connector, go by the jumper position according to how far it is from the power connector.
If you're using a hard drive on the same data cable that has two ways of setting master, if the hard drive is set to master and shows up in the bios and in Windows but the optical drive set to slave doesn't show up in the bios, either you used the wrong Master setting or the optical drive is defective. )

There is no jumper setting combo that will cause a drive that is not defective to not at least briefly spin when you press the button on it and eject and retract the tray - only a shorted data cable or a defective drive can cause that. .

Did you unplug the power supply BEFORE you plugged the power connector into the problem DVD drive ?
If you didn't, you may have fried the drive yourself.
ALWAYS unplug the power supply, or otherwise switch off the AC power to it, when you are plugging in or unplugging anything inside the computer case, otherwise it's likely you can damage something. The power supply is always powering some places on the mboard even when the computer is NOT running if it has live AC power to it, and plugging in the power connector to a drive can produce a spark that damages the drive's circuits or the power supply !
I fried an el-cheapo supply once when I forgot to unplug the PS, when I got a spark plugging in a power connector to a hard drive.

Always with the same problem DVD drive on the data cable ?

Turned off what ? You must remove the AC power to the power supply.

"disk to make sure it wasnt drive"

HUH ?

Your explanation of the problem sucks. How many total IDE devices do you have & how are you attempting to configure them? If you have 2 drives (one HDD, one DVD), it would be best to have each of them on their own cable/channel, both jumpered as master. As an alternative, you could have them on the same cable/channel - HDD as master, DVD as slave - but this is not optimal. And if you have a Western Digital HDD, there are different jumper settings for master (single) or master (with slave).

If you have more than 2 IDE devices, the config varies depending on what you have. You need to explain your setup in more detail.

What is the make and model of the mboard ?

There is no IDE drive jumper setting, or jumper setting combo, that will cause a drive that is not defective to not at least briefly spin when you press the button on it and eject and retract the tray, when the power connector is connected to the drive, there's nothing wrong with the power supplied to that connector, and the computer is running - only a shorted data cable or a defective drive can cause that.

It's also possible in theory an IDE header's circuits on the mboard could be damaged and cause the drive to not spin when the IDE cable was connected to the problem DVD drive, but I've never encountered that or heard of that for an IDE header's circuits. In that case, it's probably the case that no matter which IDE drive you connect to the same IDE connector the problem DVD won't spin with, that drive won't spin either.

Does the problem DVD drive ALWAYS spin when you do that, whether the IDE cable is connected to it or not,
and it's ONLY when you attempt to access it in Windows that it won't spin, and it happens with all three data cables ??
.........

"1 dvd 1 cd 1 hard drive"

Are all three IDE drives, all are connected at the same time when the problem DVD drive won't spin in Windows ??
