I have an Acer , Aspire 5733Z-4851 lap top with 4GB ram, 500GB HDD. IT has Win7 OS. I also have a Sandisk 16 GB USB flash drive. When i insert the USB drive the computer recognizes it in the normal way. When i send a 4gb file to the USB Flash it copies
a part of the file and then the progress bar for the USB flash turns red and the copy stops. I have to go to system properties, device manager and disk drives then uninstall the sandisk cruzer usb device.
Then unplug the USB flash drive. After a minute or so i plug the usb flash drive back in and the
device will reload and work properly till i try to transfer a file. Then it fails again. I dont know if the
problem is the usb flash drive or the computer? Please help.
