Cannot Transfer Large Files to Flash Drive

Desktop System
Motherboard- Asus P7P55D-E Pro
OS- Windows Seven Pro X64
HD- 2 500 GB HD's in a Striped Array
Service Pack 1 and latest drivers installed

Whenever I attempt to transfer a large file, (lets say, larger than 1 GB) the transfer will freeze at the end. This freeze happens when only a few seconds are left, but the transfer process can only be "completed" by a reboot or removing the flash drive. At that point, the transferred file is the same size as the original, but I'm not sure if the files are transferring properly. Also, when the freeze occurs, I am unable to start new processes.

Is your flash drive formatted as FAT32?  If this is the case there is an individual file size limit that you may well have exceeded.  Reformat the drive as NTFS, but remember that not all operating systems support this file system.

There is an article here regarding file sizes for fat32:

If not file size, then you may have a problem with the flash drive itself.  Reformat the flash drive and try again, in case it is corrupted.

Forgot to mention...

Flash drives are formatted as NTFS. I've tried multiple flash drives and multiple different large files. Problem doesn't occur on small files.

Also, I just realized the problem started around the same time that I installed VirtualBox. Could be coincidence.
I have seen something very similar with my Android device, but mine was large transfers...  I was moving about 10 GB to my phone and it would get a long ways in and crash.  a reboot of the phone and pc was only fix and moving to smaller file sets.  I never found a direct solution for it either.

Just updated the BIOS. No change.

Uninstalling Virtual Box didn't solve the problem. I found a temporary workaround. I'm using terracopy to transfer large files for the moment.
Could it be that the time needed to move the files is bigger that the time the USB port is fedding power to the USB Flash, check the power savings of your system

If you're using WIndows Exploder, try a command line, either with
      Copy +b file destination
or using robocopy.

Did I say "Windows Exploder"?   I must have meant "Windows Explorer"!

xema- Sleep and hibernation are disabled. I unchecked "turn off this device to save power" on all of my usb devices in device manager. No change.

Terracopy seems to be doing the trick. I set it as the default copy utility. I'll just stick with it. (link to download if someone has the same problem)

I just thought of this when you spoke of Power settings go to power settings and check : the USB selective suspend setting in power settings.  I use High performance as my default so I know it is disabled, but on the laptop it is usually enabled.
