I C plate starts at 0 x18fffff000 out data, which is the last eight sector read out data, later found that other dish, too, is roughly the last eight sector read out data,
The diagram below, spectacular watershed, a large AA AA AA AA,,,, is can't read data, before the show 0 can be read, who know how to solve?
CodePudding user response:
Mend WinHEX, 0 x18fffff000 behind is data,
WinHEX under fill again at the end of the data, the end is 0 x18ffffffff, there are data,
Is 0 at the end of my program is x18ffffffff, but couldn't read the data, all is the initial value AAAAAAA...
