Sager NP9150 HDD Corrupt?

Been having some problems with this laptop. First the screen died on me (replaced) then the battery wouldn't hold a charge (replaced) and now this

Warranty is expired.

My laptop has a 180GB SSD containing the OS and another 1TB HDD for videos, games, and music.

One day while playing and recording gameplay on the laptop it suddenly crashed. Recording capture was being saved to 1Tb HDD. After the crash the laptop would not start up. All I could do was get to the bios screen and tweak with the settings there. After numerous restarts and not really tweaking with the bios screen the laptop finally starts-up properly and I can log in and do things like normal. However, the 1TB was not detected at all by the laptop. It simply was not there. Going to the disk management section it detected the 1TB HDD but could not access it. I decided to format the hard drive. After formatting the hard-drive I could access it like normal. But when I went to save things to the drive it would give me errors. Downloading a video an error would come up saying fatal device hardware error. When re-downloading my games from steam it would say that there was not enough space on the hard-drive or fatal disk error. I would then restart the laptop but it would not start up again leading me back to square one. Before the restart the laptop was working fine operating from the SSD everything was normal. Downloading videos and even playing games that was saved to the SSD worked just fine. Inserting the Windows 8 disk and trying to run automatic repair, system restore, and system refresh, command prompts, nothing worked. On a random start up it would say scanning and repairing drive Z (1TB hard-drive) After about an hour of that the laptop starts up normal. The laptop was running normal and could access the 1TB drive but was still giving errors when saving stuff to it. Shutting down the laptop it wouldn't start up again.

So at this point I think its a safe bet to say that the 1TB drive needs to be replaced. But if all the 1TB drive held was the games, video, and music why would the laptop fail to start up? I'm thinking if I get a new hard-drive it would still not start up properly.

 

all it takes is a couple of bad sectors and it can cause no end of problems.

see if it will let you run a sector scan using HD Tune in my link below.

even though you are out of warranty your drive might still be covered as they are normally 3-5 years depending on make.
you might be able to make a claim for a new one from the manufacturer.

 

It won't start it just hangs on the Windows logo screen when attempting to start up.

 

I apologize if i missed this in your post, OP: Have you pulled the 1TB drive in question out of the laptop and tested for the problem with just the one SSD installed? There have been several incidents where a faulty drive, be it bad either mechanically or electronically, produce some odd behavior.

 

Also try with a different hdd, just to make sure that the problem is in the hdd and not on the motherboard.

 

I removed the 1TB drive and started the laptop. The first time I got an error starting up. Then I booted from the bios and the laptop started up like normal. Restarting a few times and it would start up normally as well. Guess it really was the 1TB drive.

 

It happens quite a bit whenever the drive fails, the latter of which does not happen all that often. Try using PassMark Rebooter and set it to restart the laptop every 20 seconds. Have it run 10x (check the 'launch at Windows startup' option first). This will help you rule out that the error will come up again without you needing to intervene on each reboot.
