Recuva does not recognize my tablet

Dear Blog administrators.

I have downloaded Recuva trying to recover "missing" files that I accidentally have deleted fro my tablet.

I have a small Arnova 7 f G3 tablet running on Android 4.0.

When connecting the tablet and opening Recuva, it recognizes all the other units but not the tablet. It's true that the system does not allcate a logical drive letter to th tablet just display ARNOVA on the windows explorer.

Any tip to make Recuve to see the unit?

Thanks

Alejandro
