Windows 10: I cant access my external hard disk C drive

I have an internal hard disk which i cant access, when try to boot it, it says preparing to repair disk and will load forever, I kept it like for 36 hours and nothing happened, so i tried to repair it with a bootable win 10 usb, but the usb also wont load it will get stuck at black screen, but it works fine on other pc , so usb is good. So then i bought an internal harddisk connector and tried to format the harddisk with other laptop i have. So i can format all other partition except the C drive. As soon as i right click on the C drive my file explorer will crash.even just connecting and disco

No access to external hard disks after last window 10 update

hello Petra

Method 1:

Check whether the external hard disk is detected in Device Manager, right click on it and click on Uninstall the drivers. Plug in the external hard drive again so that Windows automatically installs the drivers. Check if the issue persists.

If the issue persists, go to the External hard drive in Windows Explorer, right click on it and select Properties. Click on the Security tab and then click on Edit and click on Add and type Everyone and press enter. Select Everyone from the list and place a
check mark in Full control. Press apply and ok and check if you are able to access the External hard drive.

Method 2:

If you are still unable to access your hard drive, I suggest you to refer to the steps mentioned in the following link and try to take the ownership and check:

"Access Denied" or other errors when accessing or working with files and folders in Windows

external hard drive

Hi Chrpee,

If you can't find external hard drive on Disk management than the next step is using the diskpart via command line, please follow the steps below:-

On the keyboard hit ((Windows logo key + R key)) than type ((CMD))

Now the windows command line will appear, the next steps is to type ((diskpart))

After that type ((list disk)) to show you the list of hard disks with partitions

If you found your external hard drive one of the list than you need to type ((select disk number)), note: the number is a disk number

Once you selected the hard disk or partitions than type ((clean))

than type ((create partition primary))

than type ((select partition 1))

than type ((active))

than type ((format fs=ntfs quick))

than type ((assign))

last type ((exit))

Check if the external hard drive appeared, if not please see the link below for more info and let me know if you need any assist

External hard drive is showing up as local disk drive

Hi,



Thank you for writing to Microsoft Community Forums.



As you have mentioned that the external hard drive is showing as local disk drive instead of a USB drive, it is because the file format for the external hard drive is same as the internal hard drive and that’s why it is showing
up as a local disk drive and not a USB drive.



Also, since you are facing issues while changing the drive letter of the drive, for further clarity on the issue and to guide you accordingly, respond to the questions listed below:

1. What is the make and model of the hard drive?
   
2. Were you able to save or create a file on the hard drive previously?
   
3. What happens when you try to copy and paste the data from the hard drive?
   
4. What was the result of check disk performed on the drive?
   

Since you are receiving the access denied error, I would suggest you to check if the user has appropriate permissions to read/write data on the external hard drive. Refer the article

"Access Denied" or other errors when you access or work with files and folders in Windows, refer the section
I cannot access, change, save, or delete files and folders.



Note:
The above article applies to Windows 10 also.



Please get back to us with the above information to assist you further with the issue.



We await your response.
