Hi,

my name is Tom, I'm from Poland. This is my first post here, so I'm sorry If I'll do something wrong...My english isn't perfect either.

 

Yesterday my Dell Precision M6700 was working fine, but something happened when I inserted a USB flash drive. I wanted to copy a few files from my hard drive to a USB flash drive. Suddenly everything stopped for a moment (freezes), then some error message has appeared, then...a blue screen appeared.

 

When I restarted my laptop, this message has appeared: "Invalid Partition Table!".

I can't log to Windows. I've tried to use my Windows Repair Disc, but it didn't fixed the issue.

 

I think this is a malware problem, but I'm not sure. I don't want to do anything on my own, cause I'm afraid I'm gonna lose my data. If someone can help me with this I would appreciate. This is my working station, so I can't work now. This REALLY is a horrible feeling :(

 

My laptop's specs:

Dell Precision M6700, i7-3720Q

Windows 7 (64bit)

16GB RAM

A-DATA 128GB 1,8'' mSATA SSD (System C:)

2x hard drive 500GB 

 

I really appreciate any help you can provide

T.

Can you get into Repair Mode, via booting the Windows Installation Disk, and selecting Repair.  You will be presented with a Windows Command Prompt, and in that window you would want to type in "chkdsk /f c:" let it run, and see if it fixes it.

It seems to be a known issue impacting your model of lap top.

I have tried all the sugestions - nothing happened. The message "Invalid Partition Table!" still appears...

 

I'm pretty sure it can be a virus called Sochi.703 

--> http://www.securelist.com/en/descriptions/53948/Virus.DOS.Sochi.703?print_mode=1

 

Does anybody knows how to remove it?

As the virus you think is in your system is from 90's, every single av program would instantly detect it. Also, because it's for DOS, it's impossible for you to have it in your system.

Those suggestion's seem to have worked for the people having your same issue.  My only advise is to mount the drive on another system and get data off of it and to reformat it.

 

You can also try using a Linux Live CD to retrieve the data off of it.

Hello Tom, lets have a look at your hard disk's MBR.

Try this please. You will need a USB drive.

Download GETxPUD.exe to the desktop of your clean computer
  • Run GETxPUD.exe
  • A new folder will appear on the desktop.
  • Open the GETxPUD folder and click on the get&burn.bat
  • The program will download xpud_0.9.2.iso, and upon finished will open BurnCDCC ready to burn the image.
  • Click on Start and follow the prompts to burn the image to a CD.
  • Remove the USB & CD and insert it in the sick computer
  • Boot the Sick computer with the CD you just burned
  • The computer must be set to boot from the CD
  • Gently tap F12 and choose to boot from the CD
  • Follow the prompts
  • A Welcome to xPUD screen will appear
  • Press File
  • Expand mnt
  • sda1,2...usually corresponds to your HDD
  • sdb1 is likely your USB
  • Click on the folder that represents your USB drive (sdb1 ?)
  • Press Tool at the top
  • Choose Open Terminal
  • Type the following and press enter:

    dd if=/dev/sda of=mbr.bin bs=512 count=1
  • Press Enter
  • After it has finished a file will be located on your USB drive named mbr.bin
  • Remove the USB drive and insert it back in your working computer and navigate to mbr.bin, zip it up and attach it to your next reply.
This will allow me to have a look at the MasterBootRecord of your drive and see if it is infected.

regards, Elise
