This disk is only bootable by OS X from the Mac Boot Backup partition at the moment. The problem is with the Mac Data Backup partition in Bay 4. Win Boot Backup - 1TB NTFS (not bootable as of yet)īay 5: Mac Data 2 - 3TB HFS+ HDD RAID 1 (1TB unused)īay 6: Mac Boot - 1TB HFS+ SSD (bootable) The drives and partitions in the computer are like so: Bay 1: Win Boot - 1TB NTFS SSD (bootable)īay 3: Mac Data 1 - 3TB HFS+ HDD RAID 1 (1TB unused) So, how do I fix the GUID to make this partition show up? Assuming this is actually the fix, of course. Usually I make a tarball in the OS X side and untar in Windows. I will attempt to copy off the data in Windows, but I would much prefer to get access from OS X since there are sometimes errors copying files from HFS+ to NTFS, due to symlinks and certain characters. I tried using the new link format.Īs of last night there are no SMART errors on any disk in the system. I searched for "apple discussions archive".

I even found a thread that links to a solution, but the target is dead. Apparently this is due to windows overwriting the GUID for the disk and changing the partition's designation from HFS+ to FAT. I can see the drive and its contents in Windows. After changing the drive letter in Windows diskmgmt.msc, I can no longer see the drive in OS X.
