Restart your PC after changing the driver letter. This way, you can resolve the accessibility issue if it was due to the assigned drive letter. If not, do not worry, as we have one more fix left.
Fix 4 – Format the Drive
After you have tried everything, you should save the drive and keep it usable. If the current data on it has gone corrupt and is not allowing the drive to open, you may not have a choice other than formatting it. Use the NTFS file system to format the drive; you should be able to use it again.
Step 1 – Press Win+X to bring up the quick access menu.
Step 2 – From the menu, click on Disk Management to open the tool.
Step 3 – In the Window, select the partition of the drive that you cannot open and right-click on it.
Step 4 – Find the Format option in the menu and click on it. 
Step 5 – Ensure that the NTFS file system is selected and click on OK to complete the process.
After successfully formatting it, you can find that the drive is now accessible. However, the data you had will be lost. To get the data back, you can try data recovery software, as it is possible to recover data from formatted hard drives.

thanks
Hello Neil,
Regarding your query, please note if the drive is formatted with the NTFS file system, only then can you see the Security tab. To check the file system, open the elevated command prompt and type get-volume.
You will be able to see the file system.
If it is FAT32 or exFAT Security tab will not be there.
However, if your driver is NTFS, use PowerShell to get the value of the NoSecurityTab registry parameter:
Get-ItemProperty -Path “HKCU:\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer”|select NoSecurityTab
If the NoSecurityTab is set to 1, the Security tab in the properties of files and folders in File Explorer is hidden from the user.
If that is the case, let us know, and we will share steps to enable it.
Thanks and Regards
