</p><p><b>TestDisk</b> is a <i>powerful</i> free data recovery software! It was primarily designed to help <b>recover lost partitions</b> and/or <b>make non-booting disks bootable again</b> <i>when</i> these symptoms are caused by <i>faulty software</i>, certain types of <i>viruses</i> or <i>human error</i> (such as <i>accidentally</i> deleting a Partition Table). Partition table recovery using TestDisk is really easy.
</p><p>TestDisk can
</p>
<ul><li> Fix partition table, recover deleted partition
</li><li> Recover FAT32 boot sector from its backup
</li><li> Rebuild FAT12/FAT16/FAT32 boot sector
</li><li> Fix FAT tables
</li><li> Rebuild NTFS boot sector
</li><li> Recover NTFS boot sector from its backup
</li><li> Fix MFT using MFT mirror
</li><li> Locate ext2/ext3 Backup SuperBlock
</li></ul>
<p>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.
