Disk defragmentation remains an essential task for maintaining optimal performance on Windows 11 devices, especially when using traditional hard disk drives (HDDs). While modern SSDs benefit less from defragmentation, many users still rely on HDDs or hybrid drives that require this regular maintenance. However, problems can arise when trying to defragment a disk\u2014ranging from the tool not working to unusually long defrag times or errors. This guide provides practical, step-by-step troubleshooting advice for users of all experience levels, and recommends Glary Utilities as a comprehensive alternative for disk optimization.<\/p>\n
