I have a Veracrypt container on a USB 2.0 drive (not full-disk encryption).

When I copy a file from my hard-drive (where Ubuntu is installed) to inside the Veracrypt container, the standard copying dialog appears.

However, the files I want to copy haven't begun to be written to the USB until I dismount the Veracrypt container. This sometimes takes a while before I can remove the physical USB safely (moving multiple GBs of content to USB 2.0).

How can I have it write to the disk immediately (or at least sooner) than when I dismount the Veracrypt container?

  • Type "sync" after you've made significant changes/edits. – ddbug Aug 21 '17 at 19:42
  • But isn't running sudo sync DEVICE harmful to the USB? – AvdnhracNTAd9ex Aug 21 '17 at 19:45
  • Command sync does not have parameter DEVICE. Just sync. It is not harmful to any writable device, except that writes to flash memory causes wearing. – ddbug Aug 21 '17 at 19:51
  • @ddbug Just verified that sync works. Add it as an answer, and I'll accept it. (You may want to link unix.stackexchange.com/questions/48235/… which shows how to monitor the progress) – AvdnhracNTAd9ex Aug 24 '17 at 4:19
