------- Additional Comments From saulius.krasuckas@elst.vtu.lt 2006-27-02 14:54 ------- The patch mentioned by Vitaly supposedly fixed corruption of a BootSector (of a FAT partition), but Hogne talks about MBR here.
Hogne, can you find out whether it was some version of Wine, which will not corrupt MBR? If so, it would be nice to make a regression test.
