Hello, I need help. I am using parallels desktop 6 for Mac. Two VM were installed, Win7 and WinXP. I just noticed that perhaps after updating to 10920 I cannot launch WinXP any longer. I got this message: An error occurred while accessing the hard disk 1 used by "winXp". Error ID: PRL_ERR_disk_read_failed (80021029), errno=34 (result to large). I did a google search, and tried to add "devices.sfilter.enable=0" in the configuration. It did not work. Please help. Thanks.
