I have spent all day trying to copy a 680GB file from an NTFS USB3.0 drive (Disk #2 below) to an NTFS USB2.0 drive (Disk #3 below) with plenty of free, unfragmented space.

I have tried it in both Windows Explorer and from command prompt using xcopy /J. The latter, after about an hour, reports,

    File creation error - The semaphore timeout period has expired.

I have tried the following to fix this:

  1. Turned off all power-saving features
  2. Updated my USB drivers
  3. Tried this

Here is my MSINFO32. Let me know of anything else I might check to debug or workaround:

Do file system and surfaces tests on both drives. Test them with the drive manufacturers' diagnostics. Take the drives out of the USB enclosures and try the task with them directly attached (via SATA or whatever). –  Ƭᴇcʜιᴇ007 Mar 31 at 19:19

1 Answer 1

It appears that this problem was related to USB drivers and/or USB3.0. I happened to connect my USB3.0 drive to a USB2 port and the problem disappeared.
