Hi netters,
I have a question and I will greatly appreciate any prompt reply from y'all.
The question is:
There is the block and character device interface in the Unix filesystem. The 
Unix filesystem uses the block device interface.
Suppose that I don't want to use the Unix filesystem and use partiton d,
say sd3d as a block device. Does this mean that the whole partition is now
one file. Can I get access to the block addresses of the partition ? How do
I read and write to the partition ? Do I just lseek and write read ? What is
the notion of reaching a block for the user ? Is it (block# * blksize) ?
Kindly reply ASAP.
Thanks a heap.
