[Bug 2000625] Re: cp command loop when using ntfs3 package

[geole0]

Second try on LEGACY computer:

I make a script based on cp command.

I try it on a normal NTFS partition in NTFS-3G.
It ends perfectly well.

I restart it on the same partition mounted in NTF3
He blocks.

I make on another disk two partitions of identical size.
 I launch on one. It hangs almost in the same place.
I launch on the other.
It hangs in exactly the same place.
This makes me open the bug.
I can provide you with some information.

Title:
  cp command loop when using ntfs3 package

Status in e2fsprogs package in Ubuntu:
  New

Bug description:
  Hello.
  I'm on ubuntu 22.04, I saw that ntfs3 is supposed to correctly write to an NTFS partition.
  I inform you that this is not the case.
  Here is my quick test

  First try on EFI computer:
  I remove the NTFS-3G package to be sure not to use it.
  When I detect that the cp command is no longer responding, I kill the process. Nothing is happening. I shut down the computer. During the shutdown phase, I am informed twice that the cp command is running.
  On reboot, I cannot access the partition. But I succeed in read-only mode.
  I run another normal ubuntu which tells me that I have to use windows to do an chkdsk
  But windows refuse to start, I duplicate by the dd command the NTFS partition in a larger NTFS partition stored in an external disk.
  Then I delete the NTFS partition from the internal disk.
  Then I repare windows.
  After restarting windows, I find that its disk space manager cannot access  to the duplicate partition on external disk.
  There's no answer. So no letter to do the CHKDSK command.
  I decide to be more methodical in order to open a discussion and make a script to see a little what is happening.
  See the rest.
