Cannot Get It To Go Into The Slot On My Desktop Or Laptop

More than likely it is damaged. Look inside the USB plug on the unit itself. Is there a piece missing? Is something bent. Compare it to another USB plug and see if it looks different. Do other USB plugs go into your two computers? Make sure you aren't trying to plug it in upside down too... I do that all of the time. Unfortunately, they cannot be repaired. Also, any information on the drive probably cannot be retrieved. If by chance, you can get it to plug in one more time, get all the information off so you don't lose it. Hope this is some help anyway.
