full card ,directory cluster rewriting

[robs18]

Hello

I have something wrong with make new file when sd card is full ( or allmost full - fat_countFreeClusters report 1 cluster free).
If memory was full and is created empty file (file_fopen) and ( directory cluster was fully used ) the new file desription make clear the lastdirectory cluster.  Cluster was reset and new empty file description was writed at beginning of the last directory claster ( not created new cluster).

I found something ( but it was fast tested and now testing for formatted card)
I function  : fat_allocClusterChain

            if(overflow){
                bufa=part_getSect(fs->part,fat_getSectorAddressFatEntry(fs,lc),IOM_MODE_READWRITE);
                fat_setNextClusterAddressWBuf(fs,lc,fat_giveEocMarker(fs),bufa);
                Cache->LastCluster=lc;
                part_relSect(fs->part,bufa);
                fs->FreeClusterCount-=num_clusters-ncl;
                return(num_clusters-ncl);
            }

sorry but send not ended post :)

i'm changing return values from (num_clusters-ncl) to (ncl) and there looks like there wasn't be rewriting last cluster.

if(overflow){
bufa=part_getSect(fs->part,fat_getSectorAddressFatEntry(fs,lc),IOM_MODE_READWRITE);
fat_setNextClusterAddressWBuf(fs,lc,fat_giveEocMarker(fs),bufa);
Cache->LastCluster=lc;
part_relSect(fs->part,bufa);
fs->FreeClusterCount-=num_clusters-ncl;
return(ncl);
}

sory for my english but not good.
