MDFScan database recovery software

MDFScan database recovery software is a software used to recover MS SQL database files after FAT32 deletion or formatting, or because the file is too large and the file length becomes 0 bytes after NTFS deletes the file and cannot be recovered. After scanning the disk with lost data, a disk image file with the extension mdfmf is formed. We reorganize the original file fragment information and save it into a complete mdf file for recovery. After the database file is lost, please do not save anything to this disk, and do not try to restore the database to a certain state or rebuild the database. The better the original disk state is preserved, the greater the possibility that the MDF file can be completely restored.

Basic introduction

MDF database files are generally relatively large and are often stored in discontinuous logical clusters on the disk. Over time, file fragments are formed. When the file is deleted or formatted, these fragmented data scattered on the disk are difficult to recover. In the FAT32 partition, after the database file is restored, the file name length, date and other information are very complete, but the database is It cannot be attached smoothly or repaired successfully. In NTFS type partitions, frequently used database file information is severely damaged after deletion. The file length will become 0 bytes and recovery operations cannot be performed. This is a recognized high In the difficult field of data recovery technology, many professional data recovery companies are helpless when encountering such problems and can only give up the data. The emergence of MDFScan software provides an ideal solution, which can achieve complete recovery without overwriting and damaging the database files. It can also repair some table data when the overwriting damage is not serious.
