Windows 10: External Hard Drive Turned To Local Disk And Not Accessible

Hi, My 4TB External Hard Drive was working well while I transfer files, sorry for my language ı am not native, And I wanted to change the speed because it was low as 35mb/ps and ı read that under policies segment there is another option for "better performance". And After I changed my setting From Quick Removal To Better Performance to boost the speed of transfer rate, the pc rebooted and Wd Elements Turned To "Local Disk F":.

I tried to access Disk Management And after I wait several seconds the HDD was showing up there but inaccessible.The File type was RAW.

I tried CMD to use "chkdsk" but the letter was not responding.And I applied D:\>chkdsk A: /f /x /r and it started the process and Identify the File System as NTFS.I thought it will work fine and repair it.But After I wait 15 hours ıt was in Stage 2 %85 and somehow it got disconneted by touch mistakenly.

Now I started it Again with D:\>chkdsk A: /f only.Should I wait for it complete CHKDSK or Format The disk ? If so How... Help Please

:)

 

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.

external hard drive connects as local disk

The hard drive(s) check out perfectly, including using the troubleshooting methods you cite. I can repeatedly remove, reconnect, read/write/delete/restore files to these drives, yet ... they appear as "local disks" and can not be changed otherwise. As
I mentioned, this is a problem for software that requires an "external disk" device for certain processes.

This morning, I checked several other similar portable external hard drives mounted on numerous computers at my work place and found "local disk" to be the case for every system that utilizes Win7, Win8, or Win10 as the OS (maybe WinXP, but I didn't have that
OS to look at). Google searches for this topic allowed me to discover that Microsoft has made this "local disk" bit configuration in the external drive hardware a requirement for Microsoft certification. Is this true?

Thanks for your assistance.

 

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:
