Hi everyone,

 

My name's Ian and I am new here. I don't know what else to do about my situation, it seems I have tried everything. I am just hoping that I do not need a new hard drive.

 

Here's the problem:

 

The other day, when I logged onto my computer, I noticed my computer running slow when trying to navigate simple things such as the internet browser (Google Chrome) and the folder directory (Windows Explorer). Furthermore, I cannot seem to download any windows updates on my system and when I perform a disk check on my C drive, a lot of files come up as unreadable (the process takes hours).

 

Here's what I have tried:

 

1. Rebooted and let the disk check finish twice. Many files were unreadable.

2. Defragging the disk drive. Didn't seem to do anything.

3. Ran MalwareBytes in Safe Mode. Nothing was found.

4. Rebooted and navigated to the "repair" section of the advanced options. Didn't fix the problem.

5. Performed a registry check using CCleaner. I don't think it helped.

 

My thought after doing all of this (aside from buying a new hard drive) is that there are some registry files missing from the OS. Either that or I have some pretty serious malware that MalwareBytes can't even pick up. I've been reading a little about ComboFix, but I understand that is a complicated program and I should only run it with expert guidance.

 

As you can tell, I am familiar with how computers work, but I am by no means an expert. Could I get someone's input on the matter? Is there anything else I can do as a last resort, such as format the drive to factory settings (after I back up the files of course) or use ComboFix? I am willing to do anything.

 

Thanks,

Ian

Welcome to Bleeping Computer, Ian :)

Please download SeaTools for Windows and run a Long Generic Test on the sick computer, then let us know the results.

Regards,
Alex

Thanks Alex :)

 

I downloaded SeaTools but when trying to run it I get the following error:

 

"Could not load file or assembly 'SpawnCLR.dll' or one of its dependencies. The specified module could not be found. Void StartLink(Int32)"   :\

 

What should I do about this? I am in Safe Mode with Networking right now, is that a problem?

 

Ian

Hi Ian,

Let's try something else.

Please download GSmartControl and save it to your Desktop.
  • Extract gsmartcontrol-0.8.7-win32.zip to a folder, double-click on gsmartcontrol.exe
  • A list of hard drives will appear, single-click each disk to see Drive Information and identify your drive
    note: most machines will only have one or two entries, but an easy way to identify your drive is by its size.
  • Double-click on the hard drive to see detailed Device Information
  • Click on the Attributes tab, do you see any red or pink entries like the ones below? Please list the names in your next reply if there are any.

  • Click on the Perform Tests tab
  • Select Extended Self-Test and click Execute
    note: this test can take several hours to run
  • Allow the test to complete, the results will be displayed at the bottom
  • Please post the result of the scan in your next reply

Hi Alex,

 

I ran the software and under the attributes tab for my hard drive there was one name in pink:

 

Current Pending Sector Count

 

None of the names resulted in a failure status. That's a good sign.

 

However, when performing the test, which lasted about 30 seconds, the test result was "Completed with read failure. Check the Self-test Log for more information"

 

Here is the Self-test Log:

 

Complete selective self-test log:
 
SMART Selective self-test log data structure revision number 1
 SPAN  MIN_LBA  MAX_LBA  CURRENT_TEST_STATUS
    1        0        0  Not_testing
    2        0        0  Not_testing
    3        0        0  Not_testing
    4        0        0  Not_testing
    5        0        0  Not_testing
Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

 

Ian

Hi Ian,

I'm afraid I have bad news.

Current Pending Sector Count is a very common sign of failing HDDs. That, combined with the reported read error and the various problems that you have reported, means that your HDD already has one foot in the grave.

I strongly recommend that you backup any and all data on the drive as soon as possible - there is no telling whether the drive will fail and taking your data with it.

Hope this helps.

Regards,
Alex

Oh :( okay, at least I don't have to waste my time trying to fix the problem anymore.

 

Thank you Alex, I appreciate the help and the prompt replies very much!

 

Have a good day :)

 

Ian
