msid stored in adapter's controller
and it's permanent
Sadly, but true.
Compared the reading of the same card tFlash two adapters. Not only do they differ MSID but also other data. Just in this topic focus on the unfortunate MSID.
But there is still a chance.I undressed one adapter (the one in worse condition), and here's what I see :
The EEPROM certainly sits MSID.This chip flooded with resin is only a translator between the device readings (eg PSP, card reader) and a memory card tFlash.
If my assumptions are accurate this is out of the situation . Just reprogram the eeprom !
