Hey all... I recently bought an 8gb Corsair USB memory key. If I try to copy 300 mb files onto it no problem. If I try to copy my 4.5 GB video it says there is not enough space? Huh? Is there a limitation as to the size of one file allowed onto these things? It was the reason I purchased the 8GB vs the 4 GB. Any ideas? I tried to format it... it was already in FAT32 format and the format worked but still get the same message.
