  Dear List,
   
  Someone told me when a disk receive
  a write request, it write to the nearest free space on disk where the disk   read/write head is currently positioning, is this information correct?? If   this is true, is this a bad thing for database application?? That mean we   can't really control where the file go, for performance purpose we may want to   put certain files on the outer tracks of a disk, if the write location is   depending on where the read/write head is, how can we avoid that, can we   create subdisks from the outer track of a disk and create a logical volume   from it??
