Hello!
I have been using my Acer Aspire One 722 with Windows 7 for years and a few months ago, the usb ports stopped working correctly. When I try to transfer information out from the computer to an external hardrive or flashdrive, the files would be corrupted.
However, when I transfer information from let's say a flash drive into the computer using one of the usb ports, everything would be fine. Rather weird...
Imagine my surprise when I downloaded my presentation materials from the computer to the flashdrive and not having them open during my presentation!!! 
Other than that, I absolutely love my Acer computer. I experimented with different flash drives and different computers and narrowed down the problem to be the USB ports. I can't remember what I did, if any, to cause this to problem to occur...
Does anyone know what I can do about this problem? Anything will be greatly appreciate it!!!
Thank you very much!!!
