I was trying to read an exfat file system in linux and removed the original flag of lba.then remembered I had to install exfat-utils. The drive is still exfat but now will not mount to OSx mountain lion, when looking through diskutility I can see the hdd but the partition will not mount and I can not perform a verify or repair on the drive or partition. The hdd is external. Went back into my linux vm and managed to set the flag back to lba, unfortunately no mount in mac. Also I noticed in diskutility the info for the partition says linux but for the hdd info all is available.
Cannot back up the data via shares, linux or mac, there is over 600GB of data, art work, music, docs etc and it is all important. Also have my fiancees data on there too (you guessed it, this was a manual backup disk)
Q's: how can I resolve without erasing data? How can I back up without erasing? If I can back up all data I can then erase in mac and set the partition table appropriately.
