WD Green 3TB Internal HDD Disappears

Hi, I have a unique concern I'd like to discuss/ask:

Problem: My brand-new WD Green 3TB Internal (EZRX) HDD simply disappeared from the system completely after some time, only to be rediscovered by clicking "rescan disks" in disk management.


Here's the whole story; today I upgraded my desktop PC with the WD HDD as a single-partitioned secondary drive. Everything runs fine, I test-ran it by copying 400 GB data from another HDD into it and it's still fine. After an hour or so idle time though, it simply disappears.
Everything is still plugged in, running, cooled, and powered, but the new drive is gone with no error report of any sort. After I poked around a bit (didn't actually do anything), I tried clicking "rescan disks" in disk management and the HDD is detected and self-remounted. It works fine and no data is lost.


Question: Should I get it replaced? Will it cause data loss in the future? Or is it normal for WD Green Hard disks to do this?
As feedback, I also have a 2TB one and the same "issue" never occurred.

AND, if it really is normal for WD Green HDD to do this, I'd like to know if there's a way to stop it from happening again (because an internal HDD unmounting itself seems very abnormal to me.)


By the way, my specs:
Gigabyte ga-z68x-ud3h-b3 mobo
ati radeon HD 6850 on Crossfirex
intel i7 2600k CPU
4x4 Corsair Vengeance 1600 DDR3
3 other HDDs, Running for years with no problem (one of them is WD Green 2TB)
On Windows 7 64bit

    I'm having the exact same problem. The only, semi-acceptable, solution I've found so far is to change the power settings so the hard drive never switches to idle. The problem is that windows 7 does not allow the option of adjusting individual hard drive power settings. So, unfortunately, in order to resolve the problem my other 7 hard drives have to remain powered as well. I'm still a novice with a working knowledge of computers, but I've had hard drives fry out on me in the past so I'm not very fond of the possibility of it happening again. I would love to have an actual solution to this problem.
  2. I don't know whether or not these links will be helpful but they may be worth a read:

    I tried a search of the WD communities for internal drives and did a quick Google search but could not find a solution, only that others are having the same problem.

    How does changing the hard drives to "never go idle" fry them? Did they get fried from overheating? If that is possible then I'd like to seek other solutions as well.

    And thanks Kenrivers for the guide to turn off auto-idle. I may try them when I confirm that nothing will fry when I do.
  4. Hi everyone...

    I've been reading along a few threads lately, and I've seen a lot of people complaining about +3TB HDD's suddenly disappearing from the OS on Win7 (x86 & 64Bits altogether) -

    Well I've FOUND THE SOLUTION - (At least in my case) Maybe it'll help some of you out with your 3TB+ HDD's also :

    In my case the problem exists with a 3TB SEAGATE SATA HDD on an ASUS M5A-99FX PRO Rev2.0 MB.

    Now after reading some extensive info from the Seagate support site, It appears that it's an APM or PM setting problem from your BIOS. New drives on recent MB's most often recognize a new HDD 3TB+ in their Native UEFI format - For more compatibility you should set your system to boot from your HDD's in STANDARD mode (AHCI for HDD's).

    NOTE: Usually windows recognizes UEFI drives with no problem, it just seems that the problem in this case specifically, and for some unknown reason, concerns UEFI HDD's that are 3TB+ only... (Don't ask me why...)

    As for the as yet mystical "now you see me, now you don't..." disappearing act, that seems to occur to a lot of people, try simply going into your BIOS and under the POWER MANAGEMENT section, TURN THE HDD Power Management Options to [OFF] - (Or the GENERAL Power Management if you don't have the specific HDD PM Option)

    ...Then just reboot...

    If all is well, you should be booting up your OS in FULL with ALL your HDD's properly recognized.

    LAST THING BUT MOST IMPORTANT !!

    Regarding users with SEAGATE's 3TB HDD's specifically , If you want to be sure that you don't encounter the missing 749GB that are inaccessible under windows in the disk management console, please use SEAGATE's DISK WIZARD (Monitoring & Partitioning tool). You can DL it from SEAGATE's website or from this direct link : http://www.seagate.com/support/downloads/discwizard/ - This tool once installed will allow you to CORRECTLY Partition your 3TB HDD's allowing you to access and use the FULL DISK CAPACITY.

    Just remember that since DISK WIZARD is the tool that will properly setup your drive, you will notice that in your File Explorer tree, your drives will show up & be fully accessible with drives mounted & letters assigned... > BUT <...if you also look in the windows disk management console, Your HDD will appear as if it were NOT INITIALIZED -or- that the 2nd half 749GB partition is not accessible ,> > THAT's NORMAL.<< Just don't pay attention, this just concerns the 3TB HDD's ONLY, not your other disks. It is DiskWizard that has the handles on the large drive as Windows has trouble handling very large partitions unless you've initialized your HDD in GPT MODE (Win 7 OS has trouble handling standard MBR partitions in large formats... Mistery...) - Anyhow here's a quick recap, try this :

    1. IN BIOS : SET YOUR SYSTEM TO BOOT NORMALLY, ( NOT in UEFI) (Or just the HDD's if specific option available)
    2. IN BIOS : SET YOUR APM (or PM) Power Management to OFF (Or Just the HDD's if specific option is available)
    3. BOOT UP / CHECK DISKS IN FILE EXPLORER -or- SYSTEM DISK MANAGEMENT CONSOLE
    4. [OPTIONAL] - Use Seagate's [DISK WIZARD TOOL] to setup & partition your 3TB HDD. Link : http://www.seagate.com/support/downloads/discwizard/
    5. Hope you're happy - If so Have fun ! ;)

    6. Well... If it didn't work for you I'm sorry, it did for me though, so hope is not lost looool !!

    Greets ! -=[ M@D-M@X ]=-
