Question : Problem: Drive will not partition or format ISCSI mounted drive.

Mac server was reinstalled, patched, and updated.  I can get the application to function, however, formatting the mount, does not work.  I am getting an error -0200 error when I try to format it.  There are no error listings out there that define the actual error and fix, so if anybody has heard anything on it, i would greatly appreciate it.

Answer : Problem: Drive will not partition or format ISCSI mounted drive.

There is a list of Mac error codes in the Carbon CoreServices framework header file. To search it, you can just use grep, or the following shell script:

try this.

#!/bin/sh

# NOTE: Enter the following two lines as one line
#       without ANY additional spaces:
/usr/bin/grep "$1" /System/Library/Frameworks/CoreServices.framework/
Versions/A/Frameworks/CarbonCore.framework/Headers/MacErrors.h

Give it a name, save it and make it executable (chmod script_name 755). Once saved, you can do something like this (assuming a script name of "errcode"):

% % errcode 5402
  qtsBadDataErr      = -5402, /* something is wrong with the data */
