unallocated drive

About this tag
An unallocated drive in Windows refers to a disk or partition that has no file system and cannot be used for data storage until it is initialized and formatted. Common causes include accidental selection of the wrong file system type, such as CDFS, or corruption from third-party partitioning tools. Users may see the drive in Disk Management but cannot access it, and attempts to change drive letters or permissions often fail. Resolving an unallocated drive typically requires reformatting or reassigning a proper file system, though data recovery may be needed first. These issues are frequently discussed in the context of Windows 7 and external media like SD cards.
