How to save missed data on the computer
In many cases, files that have been deleted on the hard disk still exist until new data overwrites them. If data recovery programs can find these files before they are recorded. You are so lucky
If a file is accidentally deleted or cannot be accessed because the hard drive is corrupted or the file system (file system) is damaged, remember the golden rule of data recovery: Take action quickly ! The more hard drives you use, the more likely your data will be overwritten and lost forever.
If the files are deleted by: Clearing the Recycle Bin, or pressing Shift and Enter simultaneously (to delete directly without Recycle Bin), the files are still not deleted. Windows only changes the first character of the file name in the file storage system. Therefore, these files will be ignored by the operating system. Windows only marks as a space to store files on the disk, allowing other files to overwrite. To recover deleted files, you need the tool to restore the original file names and delete these bookmarks before overwriting Windows and other applications.
Symantec's SystemWork 2006 toolkit ($ 70) includes file recovery programs. Another trial for Ontrack is EasyRecovery Lite 6 ($ 89). And another free utility is Brian Kato's Restoration.
If you use Windows XP or Windows 2000, make sure the programs you choose support the file systems you are using. Maybe it is FAT (less used), FAT32 (used in Windows 98, ME) and NTFS (used on Windows NT / 2000 / XP / 2003 operating systems). Windows 98 / ME versions cannot read the NTFS file system. Windows NT / 2000 / XP / 2003 operating systems read all FAT, FAT32, and NTFS file systems. Not sure what format your hard disk uses? Select My Computer, right-click the hard disk icon, select Properties, and see on the right of the File System.
When you format the hard drive (format), you create the index for each file on that hard disk. This index is known as FAT (File Allocation Table) in FAT 32 and MFT (Master File Table) in NTFS. If this index is corrupted by virus or overwritten by the format, Windows cannot find the files in this drive.
Data recovery programs can recover FAT and MFT from backups, or reconstruct the structure. If the index cannot be edited, good data recovery programs can still identify and recover lost files.
EasyRecovery Lite not only recovers lost files, it can also recover and repair any corrupted files such as Word and Zip. EasyRecovery Lite has a search mode to recover RawRecovery data from a failed hard drive, when no directory exists.
