Every so often my Win 7 PC will boot into the startup repair loop, leaving me to either re-image or rebuild the BCD.  I'd really like to figure out what is causing this so I can fix it for good.
 
I read somewhere that a bad HDD could cause this, but I don't want to pull the trigger on a new one until I'm sure that's the problem.
 
So if anyone knows what generally causes this to happen, I'd appreciate the help.
 
Thanks.

Hi

 

Yes, a failing hard drive can cause the file system to corrupt which leads to continues startup repair. You don't need to change the hard drive without confirming whether it is faulty or not. Please run the hard drive manufacturer's diagnostic tool and verify the health condition of the disk first.

 

It is better to run the bootable version of the diagnostic tool than the Windows version. 

 

:step1: For Western Digital drives, use WD lifeguard diagnostics :  http://www.box.net/shared/gl0fifqgj4

 

Run "extended test" to verify full sectors.

:step2: For Hitachi drives, use Drive Fitness Test :

 

 http://www.hitachigst.com/hdd/support/downloads/dft32_v416_b00.iso

 

Run advanced test with it.

:step3: For SeagateSamsungMaxtore and other brands, use Seatool for DOS :

Run "long test" with it.

I recommend using Imgburn to write ISO to blank CD.

Report whether the diagnostic test detects any errors during the test. If the tool offer to repair any found bad sectors, please cancel the repair. Repaired drive won't be reliable for data storage.

It's a SeaGate HDD, so I used SeaTools, which does not detect the drive...

Hi

 

You need to switch the SATA mode to IDE from AHCI for Seatool to detect the drive. After the test is complete, make sure to switch back the SATA mode. Otherwise Windows won't boot.

Still no detection.  I was, however, able to run HD Tune:

 
The Error Scan comes up clean:

Here is the health scan (not really sure how to read this):

Hi

 

That looks clean. However, i rely on manufacture's diagnostic tools. Since Seatools for DOS didn't works for you, try Seatools for Windows.

 

http://www.seagate.com/support/downloads/item/seatools-win-master/

 

It requires Dotnet Framework 4. If it is not already installed, download from the below link.

 

http://www.microsoft.com/en-in/download/details.aspx?id=17851

 

 

If Seatool also certifies your hard drive as healthy, you don't need to change the drive. Sometimes this type of issues can be caused by a faulty SATA data cable. Replace it with a good quality one. Also make sure the system is clean from infections. Some malwares. especially Rootkits are known to damage boot sector.

SeaTools for windows does not detect the drive either.  I have a CPU cooler coming in the mail tomorrow, so I'll check the connection/swap the cable then.

 

Thanks for your help
