Hi guys, im new to this website, just thought i might get some help here.
My story is:

recently i got a worm by the name of: W32/VB-CYG
what it does is create a bunch of registry entries to execute itself on boot, and also copies itself bunch of times on all removable drives.

well it took me a while, but i think i finally got it off my system.
but next day, when i rebooted my computer, the windows xp login screen will not load, it just stay as a blank black screen.
so i decide to remove my second hard drive which i use for data backup.
guess what? windows boots normally, and i login normally.

so i plug it back in, and then it wont load the login again!
so, does anyone know what might be wrong? do you think the hard drive may be dead?
the thing is i have over 10GB of photos, 15GB music, and over 50GB of other data on it!
is there anyone that might be able to repair it if it is dead?

thanks in advance!

I'd suspect that the malware has hosed your Windows installation. I suggest a repair install of XP (it'll leave your programs and data intact): http://www.michaelstevenstech.com/XPrepairinstall.htm
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

i just went to windows recovery console, and did "chkdsk" on the drive, and it repaired the errors i guess.

I'd suggest running the chkdsk command line program to identify any errors or damages in the hard disk drives (HDDs).

Plug in both your HDD's, ensure to attach all power and data cables before you start up your system...otherwise you're going to have problems, have to shut down and check your hardware connections. Do it right the first time to avoid having to repeat steps.

Pop your WinXP boot CD into your CD- or DVD-ROM drive.

Boot your system into Safe Mode with command prompt if you can. When the BIOS splash screen shows up, start pressing F8 to enter into the Safe Mode command choice screen. (F8 is to boot to safe mode on most computers, but may be different on your model). Select Safe Mode with Command Prompt.

After you press Enter to select the desired choice, the Windows kernel should launch and show the command line equivalent of the hardware drivers and profile being loaded. It may take a few moments while it loads the necessary drivers from disk. But once it finishes, it should open up a command prompt window asking which OS you would like to access.

Select the Windows XP OS that you wish to repair. If you have only a single OS, simply type 1 and press enter.

You will be prompted for your local administrator password. Default administrator password for WinXP is blank. Enter your password and you will be validated to use the command prompt.

First, if you have never performed or used CHKDSK.EXE before, it might be a good idea to read the Command Prompt Help menu regarding this utility. To read the Help menu, type chkdsk /? and press Enter. Read the menu to get a basic understanding of what the syntax and actions of chkdsk.exe are.

Once you have an idea of what you will want to be doing, type the command and desired action flags.

In most cases, the following string should get the process going and will probably get you back up and running:

chkdsk [driveletter:] /p/r

Give the computer time to run through your entire HDD. The bigger your HDD, the more space, sectors, and therefore surface area to check and possibly repair. Once the chkdsk.exe utility has completed scanning, repairing, and rebuilding your HDD, your disk scan and repair statistics will be returned. The Command Prompt will display the C:\> or C:\WINDOWS > prompt.

You will probably want to perform this task for both HDD's since you have a multiple HDD system. You can type Exit and press Enter to restart your system. Allow it to boot from the HDD not from the CD-ROM (or you will have to restart your system and boot from HDD).

That should get you back to a usable point with both your HDDs.

OR

Boot from CD.

Once the CD-ROM boot sequence completes, select press R to select Repair. From the repair and recovery console you can access the command prompt and run the steps above.
