[Bug 1802821] Re: Serious design flaw using large external drives.

I am a Linux newbie. How do I do what you asked?

The question is moot for me. While waiting for more than a month for a
response to my bug report, I have already found a workaround. I
reformatted the drive from NTFS to ext4. This solved the problem for me
but I lost the capability of a Windows machine reading my data. Given
that Windows 10 installer will not re-install windows on a large drive
this is not an issue with me. I have written off Windows as a bad deal
with no support.

However others may want to keep compatibility with Windows. In that case
the bug in the NTFS driver needs to be fixed.

Title:
Serious design flaw using large external drives.

Status in linux package in Ubuntu:
Confirmed

Bug description:
I am trying to recover data from an HFS+ files system on a 4TB
external USB 3 drive. Copying 3TB from the 4TB HFS+ drive to a 4TB
NTFS drive using MATE Terminal cp -anR from to took 2 days.

When I try to copy the same data to a 6TB NTFS USB 3 drive the results
are glacial. 750GB has taken over 6 days. Obviously there is a problem
of scale drive in Ubuntu MATE. I invite the developers to plug in a
12TB drive and see just how glacial (no - not glacial, more on the
order of plate techtonics) slow their design is.
