 This function returns in the <desc> argument a pointer on a buffer descriptor contained in a File_Cache. It can be used for a file or for a directory.
-The searched buffer is identified by the <inode> argument. The <cluster_id> argument is the buffer index in the file. The <writable> argument define the behaviour in case of miss in the File-Cache:
+The searched buffer is identified by the <inode> argument. The <cluster_id> argument is the buffer index in the File-Cache. The <writable> argument define the behaviour in case of miss in the File-Cache:
  * if [all clusters (from 0 to cluster_id) are already allocated in FAT] it scan the FAT to find the cluster index on device, and load the missing cluster in the File-Cache, marked as dirty if writable is set.
  * if [not writable and all clusters (from 0 to cluster_id) not allocated] it returns an error.
