Data drive failed, but works in another system

[spnorton]

My Win7 system uses an SSD for primary OS drive, and a 4TB data drive for all documents. Lately, that data drive has been flakey and occasionally just "disappears" from Windows. A reboot always brings it back... until last week.
So I pulled it and attached it to my secondary PC and it came up just fine. I offloaded all the files to my NAS device, and there were no problems. So, I finally reinstalled it in the primary PC, and it won't read it at all. My Asus Z87 MB has 2 sets of SATA ports, so I attached it to the second group of ports, and the system saw it, and installed the device driver, but then said there was an error, and it disappeared. Subsequent reboots never brought it back.
I tried every trick I know, including resetting BIOS to default, and it just doesn't show up. Computer Management Devices do not see it at all. So, I finally tried a different drive, and the system saw that one just fine. Grrr.

SO, I guess I have to assume it must me an issue with the drive itself... It's a WD Black that's less than a year old and I've never had another WD drive fail on me. I'm confused that my secondary PC saw it just fine, and I was able to access all the files on it. Do you think it's REALLY the drive, and I should just replace it, or might there be a way to reset it in such a way Windows thinks it's a new drive altogether, and reinstall its device driver? TIA

Bad SATA cable, maybe?

Bad SATA cable, maybe?

I thought of that and swapped cables... no change.
It's an enterprise drive, so there's a 5 year warrantee. Decided to just say screw it and have WD send me a new drive under warrantee. Should be here next week. Still perplexed, but I'm probably just going to have to chalk it up to one of those "computer things" and move on. If the new drive also fails, THEN we have a problem. I'll update this thread after I get the new drive.
