Larry,
After reviewing the documentation I have on AmigaDOS, it appears that
there is a way to get access to the sector contents.
Even though I have used FileLocks before, somehow I never noticed the field
in the FileLock which contains the disk block number. Now all I need to do is
get more information about the DOS packet ACTION_GET_BLOCK. From the name it
appears that this packet lets you access the complete block contents, but I
have found no documentation about this packet.
Thanks for encouraging me the other night to take another look at the DOS.
It sure will be alot easier if DOS meets my needs than worrying about different
device drivers.
