Supports 32GB SD card defective

After introducing my 32GB micro SDHC card, the Sansa Clip Zip screen remained frozen on the "Update Database". I reiterated and waited several hours (connected to a USB transformer, otherwise the battery is drained during the refresh operation!) Without success. The problem is listed on the official website of Sandisk and on many forums, but none of the proposed resolution methods has worked for me. Formatting or changing the micro SDHC card gave no result.
Having acquired this drive to its high potential ability and not for 4GB of origin, I am compelled to return the Sansa Clip to Amazon. Too bad, the musical qualities of this device seemed to appointment.
