Hey there! @txbabydoll, Thanks for stopping by the HP Support Forums!
I understand you have issues backing up your HP Slate 7 Voice Tab to your PC.
Don't worry I'd like to help you out.
Did you make any changes to your tablet?
Have you tried checking with a different USB cable or different USB port?
Please provide the product number of your tablet to assist you better.
Try the steps recommended below to backup the tablet.
The charging cable that came with your tablet can also be used as a USB data cable. Unplug the USB connector from the AC adapter, and plug it into a computer USB port. Connect the micro-USB end of the cable to the tablet. The first time you connect the tablet to your computer, the tablet driver should install automatically. When the driver is installed, the tablet should appear in your computer's file manager as an external storage device. Browse to the files you want to transfer, select the files, and then copy them between the computer and the tablet using your preferred method (for example, in Windows 7 and 8, drag and drop the selected items to copy between the computer and the tablet).
