With Nextor call (_RDDRV, 73h) partitions can't be accesible #10

Closed bladeba closed 5 years ago

bladeba commented 5 years ago

After a call to read absolute sector (_RDDRV, 73h) in a partitioned device, if you try to search for "Next FIB", the partition won't be accesible anymore...

That doesn't happen with a DISK-IO (4160h) call with the (_CDRVR, 7Bh) Nextor's call.

I can't reproduce this. Can you please send me some example code that causes the bug? Also, what is the disk transfer address when you use this function call?

That code works fine for me. I need more details: what is the exact configuration of the system you are using? (hardware, partitions mapping)
