Dead drive thanks to MBR virus or thanks to me?

Laptop brand and model: Asus K52JR
Hard drive brand and model: Seagate ST964032AS 640GB

Problem: One night, about 2 weeks ago now, I turned on my laptop and it hung at the Windows logo screen (the one BEFORE the log-on, with the shinning Windows logo). It hung for about 1hour before I decided to shut it down from the button on my laptop. I gave it about 5minutes, rebooted and now it stayed black with a cursor blinking (no POST).

So, I borrowed a laptop and looked it up and it suggested to fix the mbr through the Windows 7 Repair Disc. I did so, and also used Startup Repair about 3 times. It worked like a charm....for about 6 hours.

The problem came again this time hanging at the Welcome screen after I put my password. I decided to just full on format my HDD and re-install Windows (I'd already backed up all my important data in those 6 hours).

I did so and, again, it worked like a charm. For about a week.

The problem came again, this time I had the laptop on sleep, "woke" it up, opened up Google Chrome and nothing happened. I kept trying to open something; anything (even cmd, run, whatever) but nothing came up. So I restarted it (using the Windows restart did not work, so I had to turn it off from the power button) Again, it hung at the Welcome screen. It only did so for about 15minutes, then I could manage to download Malware Bytes and scan my PC (my normal AV is avast). It detected a Trojan virus after a full scan. It did not say what type/name/etc though.

So Malware Bytes removed the Trojan, yet the problem persisted. I attempted to get into Safe Mode and after several tries managed to do so. I scanned my PC (first with avast then Malware Bytes) and they found nothing. I decided to look for another option, and found out about zero fill format to deal with master boot record viruses (since my laptop had all the symptoms I found about those nasty ones).

I downloaded SeaTools for DOS, burned it on a disc (of course, on another laptop) and ran it on my PC. First, I did the zero fill (long) when it was done, I did a Long Test. When I came back, it had found 1 bad sector and had fixed it. So I did another zero fill, and when I got back about 6hrs later to my home, it was frozen. I could not move the mouse nor do any action, and the application's clock was just standing still. I don't know if this was the right decision, but I had no other option; I turned off the PC with the power button. I rebooted into SeaTools DOS, ran a short test and it found a problem. Ran a Long Test and about 5% it said the test could not be finished (both times displaying error code is 6ADFDD6C, a code which I could not find in SeaGate's site). I attempted another zero fill, but it froze at about 10%.

EVERY SINGLE TIME time it froze, an extremely small, green text with black background displayed on top of the SeaTools window. All I could make out of it was that there was an error, SeaTools could not test the drive, and "Thanks for using our tools" (you're welcome...I guess)

I went through the fuckit route and re-installed Windows 7 on my PC, and here I am posting this...It should be no surprise that the problem comes back in a week or so...

What do I do? Does this all mean my drive is plain dead? If so, was it my fault for doing zero fill twice? Because I don't get how I did zero fill, then long test found 1 problem and it was fixed, and all (according to SeaTools) was fine and dandy until it froze at around 70% on the second zero fill.

Should I get an HDD NOW, or should I give it one more shot with this one?

  1. My guess is that you should replace the drive. "There is no interpretation of the failure codes as they do not indicate a type of failure, just that the drive has failed to complete the diagnostic successfully" - http://knowledge.seagate.com/articles/en_US/FAQ/208311en
  2. SeaTools is a pass-or-fail diagnostic.

    Try a more comprehensive SMART diagnostic. Look for reallocated, pending, or uncorrectable sectors.

    HDDScan for Windows:

    See this article for SMART info:
    http://en.wikipedia.org/wiki/S.M.A.R.T.

    SeaTools error codes ("test codes") are a unique encrypted number that is derived from the serial number of the drive and the number of the failing test.

    Well that seems like a not so useful use for those test codes...damn, I keep getting closer to just having to buy a new drive... Well, thanks for the info man.

    Running the DOS after I post this. Will come back with results. Thanks.

    Edit: HDD Sentinel displayed 24% health, 181 bad sectors on disk surface (original contents of these were moved to spare area) Drive found 3 bad sectors during its self test. There are 3 weak sectos found on disk surface.

    Rebooted, now it hangs at the "Starting Windows" screen; no logo comes up.

    Time to change drive?

    I think it is time to change the drive. It will only get worse with this drive.
