I don't understand why SeDiv doesn't just consult the USAG directory rather than an INI file. :?

Because USAG might be unreadable....

On IBM native you only need PCB to read/write PBAs as long as you know the PBA + VSC + Super On.

On ARM IBM native you do need a "loader". On both cases as long as you know the PBAs yourself you don't need to have a valid USAG.

So SeDiv can create ini files with "road map" so that you can read/write modules even if the drive no longer properly initialize.

Meaning if you clear SA and if you clear USAG you have no way to gain access to the rest of modules or original module location but if you have INI with definitions of "map" for the SA you can read/write to those spots by PBAs.

This is the same as MRT does with that option to load to the MRT software the definitions to know where MRT should read/write modules.

SeDiv does allow to use the ini file or as alternative you can as well supply a USAG module for SeDiv to use as the directory in case USAG can't be read from the drive.

Since i was "playing" with that ARM based drive i might have done something wrong and i might have dumped the SA using the ini definitions instead of using the USAG of the drive.... SeDiv do support 3 ways... ini file, usag of the drive and external usag. When you do have the valid USAG or when the drive initialize properly you can save the module directory to ini ....
