Re: logical block out of range

[Brandin L Claar <claar@arl.psu.edu>]

In the tradition of those who respond to their own postings I performed this
experiment again, adding a count=17916240 (17916240 is the size of sd0c
according to disklabel).  Since I didn't receive the error this time, I
assume the error was just a result of trying to read beyond the last logical
block.  To confirm this, I tried "dd if=/dev/sd0c of=/dev/null
skip=17916240".  This reproduced the error.  I also tried this on an IDE
system which responded somewhat more verbosely, but less clearly.

Anyhow, I apologize for thinking out loud on the list.
