β Helpful tips:
When your hard drive or storage media becomes RAW, running CHKDSK will fail and you will get a message “The type of file system is RAW. CHKDSK is not available for RAW drives”. In order to get it back in use, you will need to convert the RAW file to NTFS or another Windows compatible file system by formatting it. When you format your drive, you can assign a new file system to it, thus making it usable.
Note that formatting the drive will delete all its contents. Therefore, be sure to backup the necessary data. If there is no data on it or you don’t need the files, you can directly format your hard drive.
1. Press Windows + R, type diskpart, and hit Enter.
2. Enter the following commands hitting Enter after each line:
list volume
select volume * (* means the volume number of the RAW drive)
format fs=ntfs quick (or format fs=fat32 quick, replace ntfs with fat32 or exFAT based on your preference)
exit
The longer you use your hard drive, the more likely you are to create more disk fragmentation. Disk defragmentation is the process of putting many fragmented files all together and aligning them neatly, which can reduce file reading time and increase hard drive reading speed and is also good for CHKDSK to be able to run successfully. Follow the given steps to perform disk defragmentation.
1. Search Defrag in the search box, and then select Defragment and Optimize Drives.
2. Select the drive you want to defrag, then click the Optimise button.
System File Checker (SFC) is a tool that finds and repairs corrupt or missing system files in the system file directory, thus repairing registry corruption. DISM, on the other hand, is usually used to check and repair system image files and to detect and clean registry entries. When you encounter the problem that CHKDSK not fixing errors, you can try to run SFC and DISM scan to solve the problem. The specific steps are as follows:
1. Open Windows Start and type cmd in the search box. Select command prompt and Run as administrator.
2. In this prompt, type SFC /scannow and press Enter. Wait for the scan process to complete.
3. Run command prompt again, input DISM /Online /Cleanup-Image /RestoreHealth and press Enter. When the operation is complete, re-run CHKDSK as administrator to check if it works properly now.
If you got the error message of “Windows cannot run disk checking on this volume because it is write-protected”, it means that you cannot run CHKDSK on a write-protected external drive. Thus you need to check if there’s any write protection switch on the drive and make sure to disable it. Follow the steps below to do it:
1. Press Windows + R, type diskpart, and hit Enter.
2. Enter the following commands hitting Enter after each line:
list disk
select disk * (Replace * with the disk number)
attributes disk clear readonly
exit
