volume not mounting

I have 3 x 1.5TB drives which are split into 2 volumes, one of these volumes will no longer mount . I have run a disk utility verify / repair command with no success, it reads INVALID RECORD COUNT, VOLUME CHECK FAILED, ERROR: FILESYSTEM VERIFY OR REPAIR FAILED. How can i recover the data from this lost volume???

I don’t mean to hijack your thread but I have the same problem. I have 4 1TB drives configured with two volumes, one of which no longer shows up/mounts.

I’d like to know if you find a solution to your issue as I can’t get my other volume back!


If disk repair is not fixing the issue, Disk Warrior is recommended.
