Identical SDHC cards - different storage??!
I have two identical 16gb AData SD cards, but when I reformatted them recently (with Panasonic SD Formatter), the available space on the cards were different. One had 15.4 gb and the other had 14.9! Same card, both empty of data. I reformatted the 14.9 card again with a full format, erase on, and it came out the same - 14.9.
It makes me think that some bad sectors were found on one card and so they were blocked off from being written to.
Anyone else have an explanation?? Just curious.
