![]() The tools will execute multiple passes, endeavouring to clone the easy sectors on the first pass and leaving the more difficult sectors for subsequent passes. The idea behind these tools is to copy the storage device, sector by sector, either to another storage device or to an image file. Both tools run under Linux because Windows' error handling renders it inappropriate for this task. HDDSuperClone also incorporates a firmware tweak to stabilise earlier WD HDDs. HDDSuperClone is arguably the better tool because its author has an intimate understanding of the nature of hard disk "zones". Two free cloning tools that understand how to work around bad sectors and bad media are ddrescue and HDDSuperClone. Regular cloning tools will continue to thrash a bad sector until the read retries are exhausted, thereby accelerating the failure of a weak disc head. When a storage device becomes unstable due to physical problems (eg bad disc heads, bad media, bad NAND flash), it is recommended to clone it, sector by sector, to preserve its current state and to minimise the stress that repetitive reading will cause. GetDataBack is another popular professional tool:ĭIY cloning tools recommended by data recovery professionals It does not recover the actual RAID data, despite the suggestive name. This free tool (by the makers of ReclaiMe) autodetects the parameters of a broken RAID: Its developers provide free tools for specific tasks. R-Studio is probably the second most popular tool used by the pros. This means it can write to the drive, but not without the user's explicit approval. Its free version can recover up to 4000 files of any size from any one folder per session. The same developers also produce RAISE (US$25) which is an inexpensive option for home users.ĭMDE is probably the least expensive tool (US$20 for standard version). UFS Explorer is arguably the gold standard in the data recovery business. These tools don't feature in most online "best data recovery tools" reviews or shoot-outs, and they generally have a much lower visibility than aggressively marketed, second tier tools. It lists the most popular logical data recovery software used by professionals.
