The fullFAT driver tries to access non-existing sectors, thus making an application hang:

This function:

FF_FindFreeCluster(FF_IOMAN *pIoman)

might return a cluster which is not physically present, shouldn’t is check pIoman->pPartition->NumClusters ?

The same for :
FF_T_UINT32 FF_CountFreeClusters(FF_IOMAN *pIoman)

It may return a cluster count higher than NumClusters, thus showing a “Free Space” of more than 100%

In FF_UnlinkClusterChain()

why isn’t pIoman->pPartition->LastFreeCluster updated?

Problem is that when the disk has been full, I still can’t create new files after removing others

I found a problem in FF_MountPartition:

if ((pPart->BlkSize % 512) == 0 && pPart->BlkSize > 0) {
// Volume is not partitioned (MBR Found)
pPart->BeginLBA = 0;
} else {

On some sdcard with partitions, BlkSize happens to be a multiple of 512 and the volume doesn’t mount

Otherwise, good work! I tried it on a UC3 (Atmel AVR)

Kind regards,
