Fix 'CHKDSK Is Not Available for RAW Drive/USB/SD Card' Error
If you're encountering the error "CHKDSK is not available for RAW drive/USB/SD", there are two methods to resolve it. You can convert the RAW drive to a healthy drive using a third-party tool such as Qiling Partition Recovery, MiniTool Partition Wizard, or DiskGenius.
You can't run CHKDSK on a RAW drive, USB, or SD card. To fix the issue, you'll need to recover data from the drive, if possible, and then reformat and repartition the drive.
Your USB flash drive suddenly appeared as not formatted on your computer, and when you tried to run CHKDSK to fix the RAW file system error, Windows showed a message saying "CHKDSK is not available for RAW drives."
You can use a third-party tool like Qiling Disk Master or MiniTool Partition Wizard to convert the RAW USB drive to NTFS without losing any data. These tools can safely convert the file system and recover any inaccessible data. Alternatively, you can use a formatting tool like Rufus to create a new NTFS partition on the USB drive, though this will erase all data on the drive. If you want to preserve existing data, the first option is recommended.
When a USB or storage device becomes RAW, the direct solution is to format it. However, if the CHKDSK command is not working, you can follow the tutorial steps below to restore your data from the RAW device and then change the file system from RAW to a proper format like NTFS or FAT32.
The safest way to fix a RAW drive is to first recover any recoverable data, then use other error checking tools to check and repair the drive, and finally, reformat the drive to remove the CHKDSK not available error.
