    CHKDSK /R from command prompt just changed my NTFS disk to type RAW


    I am trying to recover from many Win10 Pro boot errors.From after initiating Automatic Repair, I started command-line prompt, and ran CHKDSK C: /R as some previous troubleshooting recommended.CHKDSK /R from command prompt just changed my NTFS disk to type RAW !Now trying to change from the repair-disk X: to C: gives "A device which does not exist has been specified."CHKDSK C: now gives"The type of the file system is RAW"CHKDSK actually harmed my system severely! Can I at least get C: working as a NTFS drive somehow?

    :)

    Command Prompt to Repair Disk

    No drive was recognized. I assumed to leave it on D: and this is what it says:

    D:\>bcdedit /enum
    The boot configuration data store could not be opened.
    The requested system device cannot be found.

    D:\>bcdedit |find"osdevice"
    'find"osdevice"' is not recognized as an internal or external command, operable program or batch file.

    - - - Updated - - -

    So I went ahead and proceeded with zbook's steps. I've pasted the steps I'm now stuck at. I don't have any volumes that display RAW as per step #21, so I don't have a drive letter to enter for step #24.

    21) type: list volume
    (look in the column Fs for any volume that displays RAW instead of NTFS)
    22) type: list partition
    23) type: exit
    24) type: chkdsk /f /r G: (change G to the drive letter of the volume displaying RAW)
    It may display "The first NTFS boot sector is unreadable or corrupt."
    This may then cont the RAW volume to NTFS.

    Can you open Elevated Command Prompt from Command Prompt?

    Please use a camera or smart phone camera to take pictures and post images into the thread.
    If you have any problems posting images please use one drive, drop box, or google share links.

    1) Find a flash drive that you can format ( > or = 8 GB )
    2) Create a bootable Windows 10 iso:
    Download Windows 10
    3) Temporarily modify the BIOS boot order so that you can boot to the external USB hard drive
    4) Insert the flash drive into any USB port
    5) power on the computer to the boot menu and boot to the external USB hard drive
    6) It may take 5 - 10 minutes for the iso to load while viewing the Windows icon
    7) Choose language, time, currency, and keyboard or click next
    8) Do not click install
    9) In the left lower corner click repair your computer
    10) Click troubleshoot
    11) Click command prompt > Administrator: X:\Windows\system32\cmd.exe > X:\Sources:>

    For these steps please use the camera or smart phone camera to take picture and post the results of the steps into the thread.

    12) type: C:
    13) type: dir
    14) type: D:
    15) type: dir
    16) type: bcdedit /enum
    17) type: bcdedit | find "osdevice"
    18) type: diskpart
    19) type: list disk
    20) type: select disk 0
    21) type: list volume
    (look in the column Fs for any volume that displays RAW instead of NTFS)
    22) type: list partition
    23) type: exit
    24) type: chkdsk /f /r G: (change G to the drive letter of the volume displaying RAW)
    It may display "The first NTFS boot sector is unreadable or corrupt."
    This may then convert the RAW volume to NTFS.
    25) type: exit
    26) reboot to open the Windows advanced troubleshooting menu > command prompt > Administrator: X:\windows\system32\cmd.exe > X:\Sources>
    27) type: bootrec /rebuildbcd
    It may display:
    Scanning all disks for Windows installations.
    Please wait, since this may take a while...
    Successfully scanned Windows installations.
    Total identified Windows installations: 1
    [1] D:\Windows
    Add installation to boot list? Yes(Y)/No(N)/ALL(A):
    28) type: Y
    The operation completed successfully.
    X:\Windows>
    29) type: exit
    30) reboot
    See if the boot problem was fixed.
    If it is fixed:
    31) Make a brand new restore point
    32) Backup all files to another drive or to the cloud
    33) Make a backup image using Macrium or Acronis:
    Macrium Software | Macrium Reflect Free

    If you get this far then you are set.
    If the problem was not fixed there are more troubleshooting steps that are based on the above results.
    Please make sure to use a camera or smart phone camera to take multiple pictures as you perform the steps and post images into the thread.

  4. CHKDSK /R from command prompt just changed my NTFS disk to type RAW

    Convert RAW Filesystem into NTFS

    So this is an interesting story. I have an USB-Stick with 64gb space on it. I so far only used it for readyboost because i didnt really find an other use for it. But today, i wanted to set up an virtual machine and needed the usb-stick. I realized i had
    an windows backup on it and wanted to delete it because it was taking up too much space. So i just moved to the recycle bin and moved on. However when i tried the media creation tool to install windows 10 on it it failed at 50% at the "Creating windows 10
    media" part. After doing some research i found out it somehow changed from an NTFS filesystem into an RAW one. I cannot access it anymore nor format it. I have tried chkdsk command in command prompt and several other external tools (most which needed payment
    so i just gave up on that) with no luck.

    In conclusion what im trying to do is change the Filesystem from RAW into NTFS.

    OS: Windows 10 Home Insider Build (Build 20241.rs_prerelease.201016-1450)

    USB-Stick: Verbatim Micro OTG USB Device (64 GB)

    Stuff i tried:

    - Command "chkdsk" with only it returning "The type of the file system is RAW. CHKDSK is not available for RAW drives."

    - Windows Disk managment

    - External tools (most which were just demanding for money and didnt actually do anything)

    Thanks in advance.
