Sorry, want I mean is that fsck dosen't support block interface
of the device if the file system is larger than 2GB or has been
mounted. From the man page of fsck on 2.5.1

Running fsck on file systems larger than 2 Gb fails if the
user chooses to use the block interface to the device:

fsck /dev/dsk/c?t?d?s?
rather than the raw (character special) device:

fsck /dev/rdsk/c?t?d?s?
