Mengembalikan File Asal Dari Format .CHK

Pernahkah menghadapi saat sukar kehilangan file yang amat penting untuk tugasan projek? Pelik bila pendrive masih berkapasiti seperti asal tetapi file dan folder hilang setelah dijangkiti virus seperti Servica.vbs. Yang tinggal hanyalah Folder yang tertulis "FOUND", namun dalamnya hanya memuatkan file-file yang bernama File Extension dalam format .chk.

Jangan risau dan panik, Tekno Daie Nur (TDN) telah menjumpai satu website yang memberikan cara2 mengembalikan file-file ke bentuk asal seperti format pdf, wmv, doc, dll.

Jom lihat website ni...

7 Ways To Recover CHK Files Created by CHKDSK and SCANDISK

One of the things about Windows is sometimes it seems to do things in a way that doesn’t really make a great deal of sense. One of those situations is when an improper shutdown is detected or something like a USB stick is detached too quickly and Windows decides it needs to run a scan of the drive for errors, which in itself is not a problem. If you decide to skip, Windows will continue to ask you to scan because the dirty bit is still set on the drive. You let Chkdsk or Scandisk run and it will repair any problems with the file system and recover or repair any corrupted files affected because of it.

The issue arises when you want to look at the files to see if any personal or important data has been affected because everything recovered by Chkdsk or Scandisk now has a generic filename of File****.CHK placed in a Folder called Folder.*** at the root of your drive! The odd thing is Windows has no utility or built in function to let you find out what these newly renamed files were before it changed them all to CHK files.
Although sometimes a CHK file cannot be recovered successfully because it has been too badly damaged, many of them can be used again, but you need to find out what type of file each one is and the correct extension needs to be applied. If Windows crashed while editing a document, there is only 1 CHK file and your document is missing, then renaming the file to mylostfile.doc could be worth a shot, but in most situations you won’t be so lucky or there’s a lot of files that need checking.

Fortunately there are third party tools around that are able to help you recover CHK files by checking the headers of the files and identifying what the type of file is and what its original extension should be. Here’s a selection of ways to help you out.

1. UnCHK
UnCHK is a free CHK file recovery tool that is able to help you restore CHK files for around 25 different file formats to their original extension. It can identify some of the most common types including audio, video, images, archives, executable files and documents. UnCHK also has a valuable feature of allowing you to add your own file type extensions by simply dragging and dropping a known good file onto the program’s icon. It will then be recognized from then onward when scanning CHK files.
Run the tool and it will ask you for the directory where the CHK files are and then a destination directory. The Scan Depth window gives various options about the recovery method; Whole Files will look at each file and check for a recognized signature, Embedded Files can pull objects like images from inside the CHK files and Floppy/Hard drive can check for cross linking in the files. The program was tested and worked fine on Windows 7.

2. FileCHK
FileCHK is about as simple a tool as it gets, and has no options or interface at all. It simply scans your CHK files and renames them with the correct file extension if a recognized file type is detected. Around 30 types of file are supported including the most common multimedia files, images, some common archives, executables and Office/text files. To use the tool all you have to do is place it in the folder where the File****.chk files are, then run it. The process takes no more than a second or two and the files it recognized will have been given the appropriate extension. Because it renames the original files automatically, it’s best to run the tool on a backup of the files in case you wish to try another utility here as well. FileCHK requires the VB5 runtimes installed to work.
