Hi there, My external HDD (LaCie Rugged 4 TB, MacOS Extended (Journaled) formatted) doesn't show up on the desktop. It is visible in Disk Utility but I can't repair it. The system returns «com.apple.DiskManagement.disenter error 49244.». Multiline Running First Aid on “DISKNAME_1” (disk6s2) Checking file system and repairing if necessary and if possible. Volume is already unmounted. Performing fsck_hfs -fy -x /dev/rdisk6s2 Executing fsck_hfs (version hfs-583.100.10). Checking Journaled HFS Plus volume. Invalid B-tree node size The volume could not be verified completely. File system check exit code is 8. Restoring the original state found as unmounted. File system verify or repair failed. : (-69845) Operation failed… BlockQuote I ran «sudo pkill -f fsck» with no recognizable effect yet. Is there anything to add ahead of this prompt in order to address the non-visible Drive ? Does anyone have any hints how to fix this issue ? @calif94577 : «sudo pkill -f fsc» or «sudo pkill -f fsck» ? (I entered the k-version and didn’t get the «2 error pop ups». Am I missing anything ? Thanks to all contributors and to you @jkrosado as well I’m on MacOS Monterey 12.5.
