joeydg Posted November 7, 2009 Share Posted November 7, 2009 I'm sure this has happened to other people. I used the FIXMBR tool (found in Partition Magic 8.0) in DOS mode to fix my XP partition. In the process, somehow it magically unfixed my GUID FHS+ format on another hard drive containing OS X.5.8. Now, I can't boot to it, mount it, or even see it correctly. My original configuration was as follows: disk0s = MBR = |XP partition1 |Vista partition 2 | disk1s = FHS+(?) = |Chameleon Bootloader partition1 |OSX.5.8 partition2 |OSX.5.6 partition3 |OSX.5.2 partition4 | From the Windows Computer Management, my disk1s shows up as one 500 GB hard drive with only one partition - which is OK, I guess, because the HFS+ is in an MBR-type wrapper(?). OSX DiskUtility sees it the same way though - just one 500GB partition. I tried using Mac's FDISK to flag a partition, but it didn't seem to help. Using a linux disk/partitioning program, all the partitions show up and the data appears to all be there... but the only partition that will mount is the partition1 with Chameleon on it. The option to mount or unmount is grayed out for the other partitions. I have tried adjusting the partition sizes hoping that it would re-write the partition data correctly, but it hasn't worked. All four partitions are marked as bootable now, but I haven't changed anything else. So, I'm finishing up on day two of this... . What's going on? How can I fix my partitions and save all of my work, programs, etc.? Any good tutorials adressing my issue? My hardware specs are listed below.

vilpostus Posted November 8, 2009 Share Posted November 8, 2009 HFS+, not FHS+ Try this tool http://sourceforge.net/projects/gptfdisk/ Link to comment https://www.insanelymac.com/forum/topic/196326-fixing-xp-on-disk0-using-fixmbr-broke-os-x-on-disk1/#findComment-1323164 Share on other sites More sharing options...
joeydg Posted November 8, 2009 Author Share Posted November 8, 2009 HFS+, not FHS+ Try this tool http://sourceforge.net/projects/gptfdisk/ Thank you!!!!!!!!!!! I didn't know what I was doing, but managed to get it fixed. Something about overwriting the backup something block or something. I am typing from my OSX on the hard drive that was broken. Now the only problem is that my EFI partition shows up in the Finder. How do I hide it again? I tried flagging it as invisible using another linux tool, but it didn't appear to do anything. I'd really like to hide it from everything else. It has my Chameleon 2 on it. As of now, I'm manually dragging it to the trash to eject it at login (so my wife doesn't mess with it).

vilpostus Posted November 8, 2009 Share Posted November 8, 2009 touch /Volumes/EFI/.fseventsd/no_log - this prevents the File System Events Daemon (fseventsd) from logging on this volume, which can cause the EFI partition to become unmountable. Then umount -f /Volumes/EFI rm -rf /Volumes/EFI From this http://www.insanelymac.com/forum/index.php...=127330&hl= guide.
