I have the same problem.
Did you manage to solve this? If so i would appreciate some help
I'm transfering files, music, data from an iPhone onto a Samsung Galaxy Tab 7.7 (International version) with Android ICS and am running out of internal memory on the tablet. I have a 32 GB Class 10 Samsung SDHC card in the Tab, but it won't recognize it or any other SD card. How can I fix this? My desktop computer is an iMac.
