TestDisk es un software gratuito data de recuperación de datos licenciado bajo los términos de la Licencia de documentación libre GNU.Fue diseñado principalmente para recuparar los datos perdidos de almacenamiento.

Summary[editar]

TestDisk queries the BIOS or the operating system in order to find the hard disks and their characteristics (LBA size and CHS geometry). TestDisk does a quick check of your disk's structure and compares it with the partition table for entry errors. If the table has entry errors, TestDisk can repair them.

However, it's up to the user to look over the list of possible partitions found by TestDisk and to select the one(s) which were being used just before the drive failed to boot or the partition(s) were lost. In some cases, especially after initiating a detailed search for lost partitions, TestDisk may show partition data which is simply from the remnants of a partition that had been deleted and overwritten long ago.

TestDisk has features for both novices and experts:

  • Recover deleted partition
  • Rebuild partition table
  • Rewrite Master boot record (MBR)
  • File Allocation Table, FAT
    • FAT12 and FAT16
      • Find filesystem parameters to rewrite a valid boot sector
      • Use the two copies of the FAT to rewrite a coherent version
    • FAT32
      • Find filesystem parameters to rewrite a valid boot sector
      • Restore the boot sector using its backup
      • Use the two copies of the FAT to rewrite a coherent version
  • NTFS
    • Find filesystem parameters to rewrite a valid boot sector
    • Restore the boot sector using its backup
    • Restore the Master File Table (MFT) from its backup
  • Extended file systems, ext2 and ext3
    • Find backup superblock location to assist fsck
  • HFS+
    • Restore the boot sector using its backup

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.
