Disk Utility & External Drive: "could not mount (com.apple.diskmanagement.disenter error 49218.)"
All of my backups are saved to a volume on a Cirago USB 3.0 External Drive and I have one Volume as ExFAT and one as Mac OS Extended Journaled because I use it between a Windows desktop and my Macbook Pro. I also had a smaller volume that was used strictly for backups. I was backing up everything via Time Machine right before leaving the computer at an Apple Store to get the USB port replaced and it kept getting almost towards the end of the backup and all of a sudden it would stop saying that the volume was ~1.5GB short to finish the backup at like 93%. I had to eventually close time machine after I asked the Genius Bar worker if the 93% that successfully backed up should reflect this fact and he said yes it should, so I ejected the drive correclty like always. No error messages. I get my computer back today and the 2 other volumes are working just fine and this backup volume (That is APFS btw) says it is unmounted and when I try to mount it it gives me "could not mount (com.apple.diskmanagement.disenter error 49218.)" This same message occurs if i try to mount the backup volume or the parent container volume. Similarly, I tried running first aid on the volume and the parent container and both check out fine but don't do anything. I tried using Terminal to input "sudo pkill -f fsck" because I read that this can fix even non ExFat issues with it, but alas it nothing. PS, sorry the volume name is a bit crass, but these things tend to always happen to me so the name is actually quite appropriate. Here are my unsuccessful steps: What I think is interesting is the line about APFS versions 1934 vs 1677; I have no idea what this would indicate. I also don't have any idea what "Exit code of 0" means. last but not least - terminal gave no insight either.
I REALLY don't wanna lose my backups and although I do have EaseUS recovery software, I don't know if It would work given the nature of the drive state. Any suggestions please??
