New HD Shows blank entry in BIOS and Disrupts boot?

Return the hard disk for a replacement; you probably have a lemon on your hands.

did you end up fixing this, I am having the same problem with a WD 1TB hard drive. It was working fine, no hardware changes it just failed.

Today is May 13th, 2013. I am having the same problem with a WD 500GB drive. In my case, this was my primary boot drive in my computer, and foolishly I have a lot of irreplaceable data in the Win7 My Documents folder structure.

I shut the computer down for an impending storm. It had been running Win7 64bit for quite a while without an issue. It shut down properly, and I unplugged it. Once the storm was over, I rebooted up, but it hung on the POST and the primary master SATA line was showing as a blank entry during the POST. I walked away from it for a few days, but I have finally come back to it. Here is what I have so far:

It isn't my motherboard, data cable, power cable or power supply. I have six hard drives in this computer. I've disconnected and reconnected each of them using different data and power cables, and while using more or less load. The BIOS recognizes five drives without fail except for this one.

I installed Win7 64bit on one of the other drives that I knew was blank. I tried to "plug and play" the bad drive while sitting in Windows. It didn't do anything.

I booted the machine to Ubuntu via a thumbdrive. I "plug and play" each hard drive in turn, and as I plugged the data cable of each powered drive (which were not connected during POST), Ubuntu immediately recognized and mounted the drives. All of them were accessible without issue -- except for the "bad drive." The bad drive never came up.

Now, a knowledgeable friend of mine is going to use a recovery program. It is on a bootable thumbdrive and is supposed to be able to recover lost data from bad drives. I'll keep you up to date.

If this doesn't work, then my last two options are as follows:

1. Attempt to remove and replace the hard drive's motherboard with one from an identical hard drive (which I have), and see if I can get to the data.

2. Call a data recovery service and faint at the price.

After that, I know I can't take the platters out without misalignment and destroying all hope. I will put the drive in a hard drive storage box and place it in my fire safe. Maybe in future times someone will have found the cure for cancer or whatever. ;-)

Oh! Two more points of interest:

It isn't my motherboard SATA ports, because I moved them around too.

The "bad drive" makes a sound. It isn't a clicking or mechanical sound. It is like a series of digital beeps. Ba-baaa-ba ba-baaa-ba .... It does this over and over the moment you plug in power. It continues to do it for almost exactly twenty seconds, then it stops. After about another twenty seconds, it starts doing it again.
