Hello, I've experienced the BSOD "KERNEL_DATA_INPAGE_ERROR" about 3 times yesterday after attempts to clean and scan my hard drive. Before I explain, here's some info:
· OS - Windows 7
· Original OS on system - Windows 7 64-bit
· Age of system (hardware) - 6 years and 10 months (purchased March 2010)
· Age of OS installation - Same as hardware age, no reinstall
· CPU - Intel Mobile Core 2 Duo T6670 @ 2.20 GHz
· Video Card - Geforce GT 220M
· Motherboard - N/A (laptop)
· Power Supply - N/A (laptop)
· System Manufacturer - ASUSTeK Computer Inc.
· Exact model number - ASUS Notebook K70IC
This computer's hard drive is partitioned into C:, with all the system files, and D:.
Here's the story:
Yesterday I was doing some clean-up and organization of my laptop's hard drive. I scanned through deleted files with Recuva, and though I tried clearing some multiple times, some wouldn't go away. I decided to do a full free-space clean up with CCleaner... the only problem being I set it to do 35 overwrites, which turned out to be a BIG mistake, as I later found out only 1 is necessary. I did the wipe on my D: drive (with "Wipe MFT Free Space" checked), and there was 36GB of free space being overwritten out of a 335GB drive (partition of 488GB HDD). Seven hours in, I had actually began reading up on if 35 overwrites was really necessary, and after I read plenty of bad things about it, I cancelled the wipe at 54%.
The actual wipe seemed successful: the junk file created by CCleaner was deleted, all space taken up by it was freed up, and deleted files no longer showed up in Recuva. However after that, I tried running a deep scan in Recuva on D:, which after a couple of short hangs, resulted in a BSoD with the error code:
I remember it having "0x0000007A" after it, however, my minidump folder is empty and I took no pictures of the bluescreen. The only way I can know is by triggering the crash again, which I obviously don't want to do.
After that, I booted up again and tried running chkdsk on D: (through Windows Explorer rather than command prompt, and checking for both system errors and bad sectors), which upon completion, resulted in another BSoD. The same thing happened after trying again, resulting in my third blue-screen. Worth noting is that chkdsk completes with no error when checking only for system errors, and only crashes the computer when checking for bad sectors.
Since then, I've been avoiding stressing the hard drive in fear of causing it to fail. I've only done some minor changes, like moving/copying some files to my external drive or deleting some files, and I've avoided playing any games or using too many programs. Other than that, I've had no problems so far: I can access files on the drive easily, I've been browsing the web with no problems, and no software has any trouble running. I only experienced one minor freeze for a few seconds, when copying a folder from D: to my external drive, but most likely, it's because the folder had many files and I had my browser playing a youtube video.
I've looked through events in Event Viewer and found errors at the times the drive started acting up yesterday, in system logs. The error displayed is "The device, \Device\Harddisk0\DR0, has a bad block.", and these errors started popping up after I cancelled the CCleaner scan. I've noticed they have also appeared sporadically over the past few months, though I've never experienced any BSoDs related to this error.
I know I caused this damage and it might lead to hard drive failure. But, what's done is done, and I want to be able to fix it as best as possible. But even regardless of if I can, what I want to know is this: considering it deals with running through all my files on the drive, would backing up my files trigger the blue-screen?
Thanks for reading my long post and for any help in advance.
For attachments, the Sysnative App didn't create a .zip by itself so I zipped the output myself. Performance Monitor failed to generate a report.
