Between 1 and 2 years ago, I started having a problem where internal drives other than the OS drive would disappear from my system and refuse to reappear. The drives would spin up and produce heat, but wouldn’t be recognized by the OS or bios. After playing around with the WD diagnostics utility (which would usually see the drive) for a while and not getting anywhere with the test results, writing zeros to the entire drive seemed to resolve the issue(s). Upon reformatting the drive, it would remain usable anywhere from a week to a few months. After this happend repeatedly over a 6 month span to non-OS internal drives, the same thing happened to the OS drive, and I became fed up with the situation. Also worthy of note, is that I RMA’d my WD Black WD1001FALS 1TB before it happened to the OS drive. Another problem that I was having at the time was that either the motherboard or video card would start squealing when under heavy video load (from what I understand, it was inductors on the video card… maybe?), so my course of action was to buy a new motherboard and processor. Upon upgrading the motherboard and processor, everything ran like a dream, no issues, until about 6 months later (now). The same hard drive problem seems to be resurfacing now, while the squealing is no longer an issue.
Since rebuilding the computer, I have acquired a Rosewill external enclosure. When two of my internal drives recently bit the dust in the previously described manner, I tossed them into the external enclosure, and they were recognized by the OS with all files intact. To be more specific, the WD black non-OS drive went first, followed by the WD green non-OS drive a few days later. When I plugged in the hard drives to another computer via SATA, they were not recognized. Also, both drives are not recognized by the WD diagnostics utility when plugged in internally, but are visible when in the USB enclosure.
This is the most accurate/recent troubleshooting information since it is fresh in my memory:
After the WD green drive disconnected while the computer was running and I realized it was gone, I tried to reboot to see if it would reconnect. After the bios screen loaded normally, the computer got stuck on a blank screen with an underscore character blinking in the top left corner of both monitors. I tried this multiple times, same result. After powering off, disconnecting the drive, and starting the computer, the same problem persisted. Upon disconnecting all of my external hard drives and booting, the OS started up. Then I tried shutting down, booting with the drive attached, and the computer booted right up with the drive not visible to bios or the OS. The drive was then put into the external usb enclosure and was recognized by the OS with all files intact.
Also, I have tried roughly 8 sata cables.
Any help on resolving/troubleshooting this issue would be greatly appreciated.
