-  DiskIo driver that layers it's self on every Block IO protocol in the system.

+  DiskIo driver that lays on every BlockIo protocol in the system.

   DiskIo converts a block oriented device to a byte oriented device.

 

-  ReadDisk may have to do reads that are not aligned on sector boundaries.

+  Disk access may have to handle unaligned request about sector boundaries.

   There are three cases:

     UnderRun - The first byte is not on a sector boundary or the read request is

                less than a sector in length.
