/dev/dsk is the block device interface and /dev/rdsk is the character 
device interface for a disk.

Utilities that need access to the filesystem blocks (like mount) use the 
blk. device /dev/dsk. Whereas tools like newfs, fsck, fdisk that require 
a character device to access the "raw" data on the device use /dev/rdsk.

HTH.
