TestDisk是一款开源的磁盘修复工具,可以修复由于软件缺陷或某些病毒导致的分区丢失或分区表丢失导致磁盘无法启动的问题.TestDisk通过操作系统查询硬盘特性( LBA大小和CHS 参数).然后会快速检查磁盘数据结构并恢复分区表.TestDisk is a powerful free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting your Partition Table). Partition table recovery using TestDisk is really easy.

TestDisk can
Fix partition table, recover deleted partition
Recover FAT32 boot sector from its backup
Rebuild FAT12/FAT16/FAT32 boot sector
Fix FAT tables
Rebuild NTFS boot sector
Recover NTFS boot sector from its backup
Fix MFT using MFT mirror
Locate ext2/ext3 Backup SuperBlock

TestDisk has features for both novices and experts. For those who know little or nothing about data recovery techniques, TestDisk can be used to collect detailed information about a non-booting drive which can then be sent to a tech for further analysis. Those more familiar with such procedures should find TestDisk a handy tool in performing onsite recovery.

TestDisk now records the potential NTFS partition location from $MFT and $MFTMirr
Location while rebuilding NTFS boot sector
A few bugs have been fixed in PhotoRec 6.8, .dta and .spss (statistical
Analysis) file format support have been added and .7z, .cab, .rar and
