Solved Computer restarts and goes to BIOS. Drive disappears.

December 27, 2013 at 11:54:10
Specs: Windows 7
I usually leave my computer running when I go to sleep. I put up a stream or some music to listen to before I doze off.

A couple of times now, I have woken up to my BIOS screen. The first time, I just shut down my machine, restarted it, and it booted to windows just fine. I came to discover that one of my hard drives had disappeared from my OS. I restarted the PC and checked the BIOS, the drive had disappeared from there as well.

I checked the connections to the mobo and psu, and everything seemed fine, but to be sure, I swapped out the SATA cable and installed the new one in a different port on the motherboard.

This fixed the issue initially, but a few days later the same thing happened. Again, while I slept, so I was unable to see what was actually happening when the system crashed.

I have checked my power settings, and discovered that windows would shut down a HD when it wasn't in use, and disabled that feature, but it has happened since I did that as well. I went into the drive properties, ran a check disc in the tools menu, and that turned up fine.

Stretching for any answers, I ran a memtest for an entire work day, and got no errors with my memory configuration.

I'm thinking it may just be a bad drive. I purchased it just a couple weeks ago, but I can't seem to think of anything else.

I was wondering if anyone could give me any suggestions or feedback.

The hard drive in question is a 2Tb Seagate Barracuda (link to the newegg page: http://www.newegg.com/Product/Produ... ) I just use it for storage, it doesn't hold any OS files on it, so I'm not sure why it would crash my whole system.

My rig:

i7 4770k
Asus Maximus VI Hero
Gskill Sniper Series DDR3 1600 (4x 4Gb.)
EVGA GTX 580
Corsair HX750 (750w)

So far (fingers crossed) adding an extra power cable has seemed to fix the problem. I let the computer run all weekend, and haven't had an issue. I'm going to give it a few more days before I mark this problem fixed.

Thanks for suggestions.

Test the drive with Seagate SeaTools for Windows:
http://www.seagate.com/gb/en/suppor...

There's a short test and a long/extended test. Test the drive with both, even if the short test doesn't find any problems.

Edit: That utility from Seagate does not work properly. It installs fine, but then my whole system locks up when it tries to scan for supported drives.

In the meantime, I found this FAQ about my Motherboard:
http://www.asus.com/support/Knowled...

"I have set HDD mode to AHCI mode because I would like to hot plug SATA HDD. However, when I tried to hot plug a SATA HDD, my system crashed and gave me a BSOD. How do I resolve this issue?


This is probably caused by the power fluctuation on the SATA HDD power wire. Some power supplies come with multiple SATA power connectors on one power wire. With this type of wires, when you hot plug the SATA HDD power, a sudden voltage drop may occur on the SATA power wire due to the additional loading from the newly plugged HDD. Operating system would detect this power instability, and execute the self-protection action (BSOD) to avoid further damage to the HDDs. To work around this issue, please use a separate, dedicated SATA power wire for the HDD with OS. This would avoid the SATA power fluctuation on the HDD with OS when you try to hot plug."

I'm not sure if this applies to my situation, but I will be plugging my main SSD in on it's own power cable to see if that helps anything.

You might want to keep the new drive disconnected for awhile and see if the problem persists. If so it's not the drive.

Do you have a system standby or hibernate set in power options? If so try turning them off.

It should be OK to let windows turn the drive off especially since you run it all night.

If it only happens when the music is playing you might try it without the music. It doesn't seem like that would be a factor but it's easy to rule out.

Have you cleaned out the computer lately - fans, vents, heat sinks etc?

Always pop back and let us know the outcome - thanks
