IDE3 is a raid port on some mobos. It needs to be enabled in the bios and the raid drivers should be installed for the port to be recognized.
124 error is usually a hardware error and that may have to do with your suspected bad drive. But that reallocated sector count, wonder how close it is to the threshold value for your hdd.
There is no raid on my secondary rig, and the controller is set to SATA, rather than RAID, so I'm at a loss on that count.
The only "threshold" that I'm aware of is specified within SpeedFan as the "warning" level, and that is 36. However, it really doesn't matter what the level is officially, because it has exceeded mine, because I can't seem to do anything on that drive. Even though it is at desktop now, it is basically dead in the water. That water must be that of "Sea"gate, which makes a sound like flushing a toilet.124 error is usually a hardware error and that may have to do with your suspected bad drive.

My decision is whether it is worth RMAing the drive, only to get another like it, but probably recertified. I happen to have another drive like this in my components collection, that the data cable's guide vane is broken on, and which they wouldn't RMA, because it appeared to be my fault. However, the event in which it was broken, shouldn't have broken it. I will probably just RMA the drive as is, because the broken one that I just mentioned is among those listed with the firmware problem and would have to be RMAed anyway.
I just took a look at both of the drives in my primary that are like the bad one in the secondary, and the values are just reverse of what I thought. The best and worst on both drives is 100, with the warning level of 36, so even though it sounds backward, it has exceeded the level.
Even though I don't need it any longer, I got curious about uninstalling via DOS Prompt, and found this in case someone else needs it:
