I have a MacBook Pro with Mac OS X and WinXP installed (via Boot Camp). I tried the latest Parallels Beta, because I wanted to try to boot my WinXP install inside Parallels. Unfortunately, I forgot that the last time i booted WinXP, I didn't shut it down, but put it into hibernation. Well, booting this hibernated WinXP from inside Parallels didn't work. After the next reboot, Mac OS wouldn't boot anymore, it hangs forever. To be more precise: Starting Mac OS in "verbose mode" gives the following endless error: "SATA warning: Completing a zero block transfer" Starting Mac OS in "singe user mode" and performing "fsck -f" gives me the follwing: ** /dev/rdisk0s2 ** Root file system ** Checking HFS Plus volume. ** Checking Extents Overflow file. ** Checking Catalog file. Incorrect block count for file mach (It should be 1 instead of 0) Incorrect block count for file mach.sym (It should be 151 instead of 48) Invalid sibling link (4, 5359) ** Volume check failed. Windows was somehow damaged, too, but I was able to restore it. Any clues?? P.S.: I searched the forum but could not find anything on this.
