External Hard Disk - Access Denied

#1 Post by DuEscon » 19 Oct 2016, 14:31

Hi,

I have an external hard disk with NTFS filesystem that I cannot access with an error : Access Denied.

This is the test disk log :

How can I restore the filesystem ?
The data seems to be intact (I can read it from Linux).
Any help is appreciate.

Run "cmd" 'right click run as administrator) and "chkdsk /f e:".
It may also be a problem of file ownership https://technet.microsoft.com/en-us/lib ... s.11).aspx
