RE: Dynamic C 9.25 FAT problems

Thanks for your answer Tom, but the problem is not the Dynamic C version. With 9.62 have the same problem.

I think that the problem is the sector leng (512 bytes). 
I create a 64 bytes buffer...
  strcpy(buffer,"0123456789012345678901234567890123456789012345678901234567890123"; 

and write this with fat_Write sentence without problem after seek the last record with 
fat_Seek(&file, 0, SEEK_END); 

If write 1, 2, 3 times this buffer all works OK. I look this by excecute 
fat_Delete(particion,FAT_FILE,filename); // return 0

I can write and delete up 8 records OK (file of 512 bytes) OK
but after write the record 9 (file of 576 bytes), when execute

fat_Delete(particion,FAT_FILE,filename);

I get the -22 (-EINVAL) error.

Have you some idea over this problem ?

Best regards and sorry for the lenght od this explanation
