Unlike an ordinary file copy, it tracks problematic regions and can continue around read errors. Its purpose is to preserve available disk data for later inspection, not to reconstruct individual deleted files or fix broken hardware.\"}},{\"@type\":\"Question\",\"name\":\"Can GNU ddrescue recover permanently deleted files?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Not directly. GNU ddrescue copies sectors without deciding which files were deleted. The copied image may still contain recoverable deleted information if it has not been overwritten or discarded through SSD TRIM. Check backups first; otherwise, compatible file recovery software can examine the rescued storage. Permanent deletion does not guarantee either success or failure.\"}},{\"@type\":\"Question\",\"name\":\"What happens if I lose the ddrescue mapfile?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Without its original mapfile, ddrescue cannot reliably resume from its recorded sector-by-sector progress. You may be able to assess an existing image, but generating a suitable replacement requires expertise and may involve additional reads. Keep the mapfile and image together on healthy storage, and make a separate copy of the mapfile before changing rescue settings.\"}},{\"@type\":\"Question\",\"name\":\"Does GNU ddrescue work on Windows 10 and 11?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"GNU ddrescue works most naturally on Linux or other suitable POSIX systems. Windows users can boot an Ubuntu live USB and run the Linux utility without installing Ubuntu on the failing disk. Compatibility layers and graphical frontends also exist, but direct disk access varies. Always verify how your chosen environment identifies physical devices before starting a copy.\"}},{\"@type\":\"Question\",\"name\":\"Does 100% rescued mean every file will open?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. A completed rescue indicates that ddrescue read the selected sector range successfully, not that every file-system record or document is logically valid. Files could have been deleted, corrupted before imaging, or damaged by an earlier operation. Open representative important documents and media from the healthy copy, then compare their contents and sizes with any available backups.\"}},{\"@type\":\"Question\",\"name\":\"What is the difference between ddrescue -n and -N?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"In GNU ddrescue 1.30, <code>-n<\/code> means <code>--no-scrape<\/code>, which skips the detailed scraping phase, while <code>-N<\/code> means <code>--no-sweep<\/code>, which avoids the sweeping phase. Older releases assigned <code>-N<\/code> differently. Therefore, copying commands from an old tutorial can change how ddrescue handles difficult areas. Always check the locally installed version and help output before using these options.\"}},{\"@type\":\"Question\",\"name\":\"Can ddrescue recover files from an SSD after TRIM?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Ddrescue can copy sectors that an SSD still makes readable, but it cannot reverse TRIM or the controller's internal cleanup. Once deleted blocks no longer contain the original information, a disk image cannot reconstruct it. If the SSD remains accessible, reduce activity and preserve a copy promptly; for unstable hardware or irreplaceable files, consider professional assistance.\"}}]}<\/script>\n                \n    <\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>A Windows file transfer stops with an I\/O error, or Ubuntu can see your hard drive but cannot read certain folders.
