Question about Tatung 12.1'' Widescreen Laptop, 1.4 GHz Intel Centrino Pentium M (TWNB12N01) PC Notebook

1 Answer

Hard drive not detected

I have a Tatung notebook TWNB12N01.  I got the "blue screen of death" a couple times in just a few minutes and it shutdown, now it will not startup at all.  It says it can't find the hard drive and there is a problem with the startupdd.sys.  I went into the BIOS to see what kind of hard drive it was to see if I could download help from their site, but it shows no "vendor" and the "size" shows "0MB". 

My question is...Is there another way to get the hard drive back up or is it just shot, and if so, can I buy a replacement hard drive and will that work?

Thank you so much for your help.

    Thanks for the help.  The computer is 1 1/2 years old...the warranty was 1 year OF COURSE. lol   

    One more question.  Can I use an external hard drive?  We just so happen to have 1 that is the exact same size as the hard drive in the computer.  This would at least suffice until I can get another one if it will work.

    Thanks again for the help.

    This, I believe anyway, is the model number. TWNB12N01  It us a Tatung.  From what I found on the inet, it sounds like it's a generic version of Hitachi. I tried to search for it, but couldn't find any info on the actual hard drive.  I haven't taken it apart yet...just in case there was something I could do instead of replacing it.  I guess I may need to take that route now. :)

Is that a new notebook?

Yes you can replace the hard drive with any laptop drive. I am not sure about the bios limitations on size, however if you got a comparable size drive you would not have any wasted space.

You can use a bigger drive, it just will not format beyond the bios max.

You may want to consider a 7200rpm drive for the replacement. It will improve your pc performance, however it will also generate more heat, so if you dont use the machine in an environment that is well ventilated, that may not be a good idea. :)

    If your laptop is only 1 1/2 years old i'm sure you can. An external drive will be much slower than the ata or Sata bus your current drive works on. But it would work.

    If you can give me the Model number of the laptop i can find a replacement for you. And if its only 1 1/2 years old, you wont have any trouble with a replacement size.

    Here is what you need. You have a generic laptop drive.

    40 GB UltraDMA 133, 4200 RPM EIDE

    So whats that mean? :)

    Just about any drive will work. I would go with "NEW" not used." target="_blank" rel="nofollow" >Here is 1

    Anything like it will work.

    Just swap it with the old drive, you wont have to remove anything, just a cover. So don't take the entire laptop apart.

    You will just put in your recovery discs after you swap them and reinstall the drive.

    If you want to recover data from the old drive e-mail me and we can setup something for you. As long as you dont mess with it to much anything on it should be recoverable.
