Need help with BSOD -- KERNEL_DATA_INPAGE_ERROR
Hey folks,

About 2-1/2 weeks ago I started getting BSODs with KERNEL_DATA_INPAGE_ERROR.

Technical information:
*** STOP: 0x0000007A
*** ataport.sys

I am running Win 7 Pro 64-bit on a custom built rig.

Following is the log from TSG SysInfo:

Tech Support Guy System Info Utility version 1.0.0.2
OS Version: Microsoft Windows 7 Professional, Service Pack 1, 64 bit
Processor: AMD Phenom(tm) II X4 940 Processor, AMD64 Family 16 Model 4 Stepping 2
Processor Count: 4
RAM: 4094 Mb
Graphics Card: NVIDIA GeForce 8600 GT, 512 Mb
Hard Drives: C: Total - 122100 MB, Free - 36178 MB;
Motherboard: Gigabyte Technology Co., Ltd., GA-MA785GM-US2H
Antivirus: AVG Internet Security 2012, Updated and Enabled

I've run memtest and chkdsk with no issues found. I've also run a Windows Defender Offline scan, and it comes up clean. I do not (yet) seem to experience the problem when running off of a bootable CD.

So what next?

Thanks in advance!

This happens when windows is unable to read hdd cached kernel data. You may first want to try to disable energy saving for your HDD completely so it stays on all the time. Second, check the power plugs of your HDD. If that doesn't fix it, it's possible that either your HDD or your PSU is faulty.

Thanks Lutia!

I've disabled power savings -- set them to NEVER for the one hard drive in the system. Assuming that remedies the BSODs, then what is the problem that needs to be fixed so that power saving can be re-enabled? Is it a drive issue?

I also see that I can enable/disable write caching via the drive's Properties. If the BSOD occurs again, I will next disable write caching.

The BSOD occurred after disabling power savings on the hard drive. I am now re-testing with write caching disabled (in Win 7 Properties). If the problem persists, I will next disable caching/shadowing in BIOS.
