I get some incorrect data with the SdInfo sketch. I'm using the latest version, 1.1.4. The card is SanDisk Ultra 16GB SDHC.
rootDirStart: 2 (should be 16384)
dataStartBlock: 16384 (should be 16448)
Do these values not depend on how the formatting was done? Or are you saying it's actually wrong for this card as it's formatted?
It's wrong, before and after using SD Card Formatter. I haven't checked other FAT32 (SDHC) cards, but FAT16 cards are correct.
Well, SdFat is written by fat16lib here. You might send him a message.
