Command: testdisk
TestDisk 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 a 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/ext4 Backup SuperBlock.
- Undelete files from FAT, exFAT, NTFS and ext2 filesystem.
- Copy files from deleted FAT, exFAT, NTFS and ext2/ext3/ext4
partitions.
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.
