Hello! It may seem like a simple problem, but I know nothing of the subject and I've had the problem for ages. Whenever I copy large files (Movie size, think 700MB+), the copy progresses very fast (~100MB/s) until it reaches about 99% where it gets stuck for about 30 seconds to a minute, and it says "Time remaining: 5 seconds" during all that time. I have this problem with any flash drive, in any USB port (2 & 3). It also happens when copying to network drives and external harddrives, which leads me to think it's a software/windows issue. Some vital information: The flash drive I mainly use is USB 3.0, quite new and easily capable of ~150MB/s writing speeds. It reaches about 120-130 MB/s during the copy until the final point where it still says 130 MB/s but does nothing for 30 seconds. USB port is also 3.0, and I've also tried every single other port in my computer. None are broken, and none ever show any signs of being slow. The flash drive is NTFS formatted, but it used to be FAT32. I ran checkdisk to see if there was anything wrong, but there wasn't. It's NTFS since I occasionally need files >4GB. I tried using TeraCopy to bypass the issue, but this way doesn't reach speeds of over 20MB/s which takes even longer in the end. It does fix the 'hanging at 99% issue'. I tried converting the drive back to FAT32, which removes the issue of it hanging at 99%, but again the speed doesn't go above 20MB/s which means it takes longer in the end, making it not worth it. What bothers me is that the files transfer at the maximum speed right until the very end, where it just magically gets stuck for 30 seconds or more, before finishing like nothing happened. Please advise!! P.S.: I shamefully have to admit I never safely remove my hardware.
