I have a new macbook pro with ML. For my first time in my life, for my little error I disconnected an external drive (ADATA sh93, 1TB) without removing it by finder before. This drive was and it is with 2 partitions here it is the names: 1- Mountain lion (8 GB HFS bootable) 2- ADATA (992GB Exfat) (Many important documents!!) This drive was sleeping, it was not writing/reading when I disconnected it. After when I connected it did not mount, so I repaired it by Utility Disk, so.. Mountain Lion's partition is good mounted on finder correctly ADATA's partition mounts on finder but is.. empty!! It is incredible for me everything is lost!!? Only for a disconected without removing by finder?? I tried to repair disk with Utility Disk 3 times but the result always empty this partition, I think that this partition has filesystem corrupted, with Utility Disk is impossible to repair permission (it is Exfat), Diskwarrior cannot repair, rebuild Exfat partition so.. Which software can rebuild an external drive Exfat? Thank you in advance, I am a little panicked cause this means many many hours of my job lost, please help me..
