Okay, last month we had a power surge and my PC shut off. When I booted it up, it detected no harddrive (primary) which is a Western Digital Raptor HDD (150GB). BIOS did NOT detect the hdd. When I shut down the computer for the day, went to work, etc, came back - computer booted perfect.
Now, it did this AGAIN but simply shutting it off and turning it back on (restart didn't work) helped it. I noticed that Windows Event Log was reporting "Bad Block/Sector" type errors. I did a HDD diagnostics scan, and everything came back fine. I can't remember 100% but I do believe there was two bad sectors.
I've been having these random freezes where my ENTIRE computer just STOPS. Not sure if this is hdd related, or what. I noticed whenever Visual Studio AUTOSAVED, it would freeze up for 10-15 seconds. It wouldn't freeze all the time. But the sad thing is, I store all my programming on a secondary harddrive (and mirror it to the external)... I don't know if VS just autosaves temp files to the primary Hard drive.
So now, today, I woke up and my entire computer was frozen. I tried to get it to come back to life, ctrl+alt+delete didn't work, nothing worked. The mouse moved, but Windows Explorer crashed. So I reboot, right before the "Starting Windows" screen and nothing shows up - just black. Eventually Windows 7 "repair" mode activates and asks me to repair. But it can't find the primary harddrive partition.
I just burned Ultimate Boot Disc Tools 4.11, and I am about to try that and then burn WD Diagnostics boot disc.
Is my hard drive failing? If so, this would be my 3rd Western Digital hard drive failure.
Does the random lock ups and freezing have to do with the harddrive failing?
Suggestions on repair tools?
