My computer does not recognise the EasyCap devise and the supplied disk is defective. how can I get it to work.

You have to be sure the computer has the correct software to recognise the hardware connected to an USB slot and can work with it. From Windows 7 and up, for most hardware that is certified with Microsoft, you can download the drivers from Microsoft. Lots of hardware is recognised when connected and will initiate a download from Microsoft. But not all hardware will do so and not all hardware is compatible with the new operating systems.
So to make sure your hardware is compatible, check the manual (or box where the hardware came in) and find out, what you have to do so it will work on your computer.
For older equipment you can't find drivers, because most producers of hardware, don't work on certification of old hardware. They only develop and work for certification with Microsoft for the parts they want to sell now.

Down load Audacity software, that will run it.

You might need to double check to make sure this is made for a Mac, PC, or Both. You might need to have it formated from the Disk Management (assuming you are using a Windows computer) so your computer recognizes the hard drive.
Here is a link.

If this does not work then it is likely you have a faulty unit and should ask for a replacement.

Maybe these will help you Videos

Media Manager is just the software that allows you to sync, the MP3 player should still show up as a Removable Disk drive under 'My Computer'. If not, check your connections, something should also appear on the MP3 player screen when connected to the computer.

Have you tried finding the right drivers for the device?
Once the drivers are installed, the device should work fine with all software that supports video capture, including movie maker.

You probably damaged the drive from sudden disconnection of the signal line. I would suggest trying it on one other computer before considering it trashed.

Please clean the usb cable. Use a cotton swab with Alcohol on it. (Not dripping). You may need to use a few. If that fails to help, try another usb device in your PC & check if the PC can see that device. The cable could be defective. The FAT on the drive could have been damaged or the drives file system could be corrupt. The usb port could be loose from plugging in & out. If your OS is Vista that can be the problem. Try a Pc running XP.
