comment Macintosh HD missing after failed catalog btree rebuilding
@bmike I have edited the question. This is not about general advice but about a specific command patrix suggested in an earlier answer that resulted in an unmountable drive. It would also be helpful if he can explain the command and the effect it has on the main volume.

@Buscar웃 I need 50 rep to do that.

@MikelR If everything fails, this will be my last resort, before sending the drive to some data recovery service.

@Buscar웃 the r in /sbin/fsck_hfs -yprd /dev/partitionName is equivalent to Rc in the original command I issued. It is this catalog btree rebuilding that caused serious failure in my hard drive.

comment Macintosh HD missing after failed catalog btree rebuilding
@Buscar웃 You mean this one? I am actually afraid of running more fsck_hfs commands unless I am completely sure what it does. The manual says it would only perform a repair when it can and would exit on error. Apparently it just wiped out my whole drive without a warning.

@Buscar웃 I tried the exact same thing before, and it gave the errors I have mentioned previously: failed to mount non-root inconsistent disk, hfs_mountfs returned 22 and invalid argument. I also tried diskutil repairPermissions disk0s2 in recovery mode. It gives Error starting permissions repair for disk0s2: Couldn't mount disk (-69842)

@Buscar웃 The drive was accessible in single-user mode before. After I tried to rebuild the btree, the drive is gone. I should have tried resetting PRAM beforehand, but now the problem is more serious than that.

@Buscar웃 I can't run diskutil in single-user mode.

comment Macintosh HD missing after failed catalog btree rebuilding
@Buscar웃 I can try, but I doubt if that would work. I couldn't mount the drive in Disk Utility, so I guess this drive is not readable in its current form.
