If the volume is damaged, try the "readOnly" option Volume on disk3 failed to mount if it has a partitioning scheme, use "diskutil mountDisk" I hope this will be helpful to somebody: Admins-MacBook-Pro:~ admin$ diskutil mount /dev/disk3 Just when I was about to give up, format the drive and lose my data, somehow I was able to fix the drive so I am posting what exactly I did in terminal for the benefit of other people who might come across this post and have the same problem. I am at a loss, can anyone give me some advice on how to mount this drive? Which gives back: Error starting file system repair for disk3: Unrecognized file system (-69846) I also tried: diskutil repairVolume /dev/disk3 Mount: You must specify a filesystem type with -t.Īnd then: mount force -t Apple_HFS /dev/disk3 So I tried terminal commands like: diskutil list The disk you inserted was not readable by this computer. I recently bought a 4 TB naked (no enclosure) external hard drive that I mount via a Newer Tech dock (the ones where you insert the naked drive like bread in a toaster) and is connected to my MacBook pro via FireWire 800.Ībout a month later I wanted to use the drive and it would not mount.ĭisk Utility reports that it is "Not Mounted".
