I did what Wishmaster suggested. According to my manual, there is a Reset CMOS button which I used and then proceeded to load the defaults. But there was still no change.
I tried the jumper switch but it still doesn't recognize the hard drive.
I wonder if I should just use a new hard drive, but I'm worried about that nvlddmkm.sys error and this possibly happening again.
The drive is recognized on another computer as a secondary drive correct?
Have you tried running a check disk or HD test from the PC that does see it?
this way we can determine if the drive itself is good or going bad.
The nvlddmkm.sys error I believe was a Nvidia driver error.
Although this will need to be addressed, this would be software related.
It should not cause the HD to be unbootable.

Yes, it is recognized as a secondary drive. I haven't done a check disk yet. I have the HD Tune Pro program and can do a test with that tomorrow. Any suggestions with it would be helpful.
Just a suggestion, backup any data you don't want to loose from the possibly failing HDD, before it's too late.
Then the HD test as previously suggested.
I tested today and the health status tab said everything was OK. I did a scan for errors and there were no damaged blocks. So, I'm rather confused.
Yours is not an easy problem to diagnose, my friend. But lets keep at it.
When you attach this drive to the two different computers you are using the SATA cable connection, using 2 different cables, and the drive is not recognized in either computer's BIOS.
But when you connect it inside an external enclosure that connects to the computer by USB it is recognized.
What kind of connections are made to the hard drive inside the external enclosure?
A SATA cable or a big IDE ribbon cable?
A SATA power connector, or the old style molex connector?
And, when the drive is connected inside the computers, is it powered by a SATA power connector?
Yes, that's correct.When you attach this drive to the two different computers you are using the SATA cable connection, using 2 different cables, and the drive is not recognized in either computer's BIOS.
This is the enclosure I'm using: Vantec NexStar 3 NST-360SU-BK 3.5-Inch SATA to USB 2.0 and eSATA External Hard Drive Enclosure (Onyx Black)What kind of connections are made to the hard drive inside the external enclosure?
A SATA cable or a big IDE ribbon cable?
A SATA power connector, or the old style molex connector?
There's a built-in plug on the plate inside. It uses the same heads of a SATA cable and a SATA power connector. It doesn't use the big IDE ribbon cable head nor the old style molex connector head.
Yes, they were powered by a SATA power connector. They are also two different SATA power connectors.And, when the drive is connected inside the computers, is it powered by a SATA power connector?
Damn!
I was thinking it could be just a bad connector or power plug.
For the others: if the MBR got corrupted, would that explain the symptoms?
This was what I suggested was possible in the Guru discussion of this thread. the fact it will work as a non boot drive. Have a look at this:
