  A. "M" naming scheme is used by the application
  B. Application uses embedded BLOBs
  C. Collision avoidance flag is set on the application server
  D. Size of the parity slices is smaller than the threshold
  C. Collision avoidance flag is set on the application server

  B. Garbage collection has purged overprotected data from the newly installed disk
  C. Regenerations are progressing but have not yet completed
  D. Regenerations have not yet started to reprotect the data onto the newly replaced disk
