cluster count within 16 clusters of required FAT format cut-over
Facility: EFI$CP, The OpenVMS EFI Partition Control Program
Explanation: The specified FAT volume has a valid format, though
the count of clusters is within 16 clusters of a required cut-
over to the next larger or next smaller FAT format. Per EFI FAT
specifications, this condition can cause instability when this
volume is accessed from certain erronously-coded FAT utilities.
All FAT12 volumes must have fewer than 4085 clusters, all FAT16
volumes must have between 4085 and 65524 clusters inclusive, and
all FAT32 volumes must have at least 65525 clusters. This volume
is perilously close to one of these cluster count cut-overs.
User Action: While no action is specifically required, the EFI
FAT specifications do recommend reinitializing the volume with a
new cluster size, and specifically with a cluster size calculated
to avoid a cluster count in proximity to one of the FAT format
cut-overs.
