Is TeskDisk safe to use?
TestDisk is more of a partition table repair tool than a data recovery tool, so, unlike other specialized data recovery tools that perform read-only operations to your volumes, TestDisk might cause further damage to the partition and overwrite some data while it is fixing a partition table, rebuilding file system boot sector, and fixing MFT.
Is the information helpful? Please help others by sharing it.
TestDisk has 3 primary features that make it a unique and useful partition recovery tool.
TestDisk can read the sectors on the storage device and analyze the disk structure to determine if the partition table requires repair. Once the partition table is successfully restored, the deleted or damaged partition can become accessible again.
TestDisk includes the capability to fix common filesystem errors, including
rebuilding the boot sector and repairing Master File Table (MFT) and directories. However, the boot sector restoration only works for FAT12/FAT16/FAT32/NTFS/ EXT2/EXT3/EXT4 file systems.
TestDisk can retrieve inaccessible files from a damaged, deleted, or lost partition. Additionally, it can undelete files from FAT, exFAT, NTFS, and EXT2/34 filesystems. However, the file undeletion feature of TestDisk is very basic because it can only recover files that were simply deleted through the operating system's deletion commands. It is not suitable at all for drives with filesystem damage, or files that were not extremely recently deleted.
Pros and Cons of TestDisk
Here are some quick takeaways from the TeskDisk review:
- Completely free and opensource application
- Recover files from most file system types, including NTFS and FAT
- It supports many operating systems, including Windows, Linux, and macOS
- It supports RAID recovery
- Effective deleted partition recovery
- No data recovery limit
- It can't fix a severely damaged partition table
- File undeletion capability is limited
- The initial setup is difficult
- Its strictly command-line interface is not friendly to a tech novice
- The macOS version that is compatible with Apple silicon needs Homebrew installation.
