Running Kubuntu 18.04.01 bionic. I've tried Dolphin and the terminal but can't copy a .MOV file from 1TB usb drive NTFS to EXT4 on an Asus laptop. The permissions of the NTFS file show world rwx and owner as me when viewed with Dolphin. Both filesystems are mounted.

The message I get from the command:

$ cp -a /media/mark/3D9578B26267F622/boat/MVI_3734.MOV /home/mark/Videos/boat/MVI_3734.MOV
cp: error reading '/media/mark/3D9578B26267F622/boat/MVI_3734.MOV': Permission denied.

(The odd looking directory "3D95..." is the how the NTFS partition is mounted in Kububtu.)

The permissions in Dolphin looks like this:


Any ideas on why this is not copying from NTFS to EXT4?

  • Do you have rw permission for the directory /media/mark/3D9578B26267F622/boat? – wjandrea Jan 11 at 3:56
  • I'm running Kubuntu 18.04.01 LTS. – MarkS Jan 11 at 6:01
  • Yes, I have permission to read and write to /media/mark/3D95.../boat. The .MOV video files will not run using VLC media player or KMplayer. – MarkS Jan 11 at 6:13

    Based on available info, must be an issue with the ntfs volume. It mounts properly, but apparently provides read errors. Might also indicate hardware failure. Have the ntfs partition checked on a Windows system (and properly unmount or fully shut down Windows). If the issue persists, then it may be a hardware issue. – vanadium Jan 11 at 11:44

    @vanadium Please add that as an answer, thanks! – wjandrea Jan 11 at 14:34

The solution here is more of how to properly save a BitLocker encrypted file from NTFS running Windows 10 to an EXT4 unencrypted filesystem running Kubuntu Linux. Opening the BitLocker encrytped disk and saving to an EXT4 unencrypted partition will NOT yield an unencrypted EXT4 file. You must first change permissions under Windows 10 to "personal".enter image description here

Enabling or disabling "fast boot" in the BIOS had no effect.
