[Solved] Unable to Erase Data from Raw Format Drive

A storage drive with the RAW format is usually considered damaged or corrupt, as the Windows PC does not recognize a RAW drive or volume. It indicates a storage drive with no file system and thus, cannot be accessed. Windows supports NTFS, FAT32, and exFAT file systems. Therefore, any storage drive formatted with a supported file system and connected to a Windows system via USB ports, SATA, or PCIe is natively supported and recognized by the Windows OS.

Therefore, if you want to erase data from RAW format drive, you first need to format the drive with a supported file system i.e. NTFS, FAT32, or exFAT. It is noteworthy that formatting does not permanently delete all files and folders from the drive. Instead of formatting only replaces the older file indexing table with a new one. As a result, the formatted files remain on the storage drive.
