I bought a San Disk 32gb micro sdhc memory card and installed it in the top slot, but the xoom does not "see" it. I am running ICS version 4.0.3 so it should be updated enough to enable the memory slot. I have tried several times to turn the xoom off, let it sit for a couple of minutes and do a restart to no avail. I currently do not have a computer with a memory card reader, so how do I format the disc so the xoom will "see" it? Can I do it from the xoom or do I have to buy a usb card adapter to use my old imac (2004) to accomplish this? Please help, thank you.
