Diskmanagement.disenter error 49218

The apple technician told me to format it with macOS plus with registration, which is a more secure format. Has anyone got the error with this format?

I have the exact same problem with a 4TB WD My Passport HDD. I upgraded to Ventura 13.2 and my disk suddenly can't be mounted anymore. First Aid refuses to do anything, and my errors are identical to those in the original post.

Fortunately I have a spare laptop running Fedora 36, so I was able to install apfs-fuse (https://github.com/sgan81/apfs-fuse), and mount the disk without any problems. I ran:

sudo dnf install -y apfs-fuse

sudo mkdir -p /media/$USERNAME/my-passport

sudo apfs-fuse -o allow_other /dev/sda1 /media/<username>/my-passport

And that allowed me read-only access to the disk and I could copy the files over.

I still haven't found a solution for the actual issue, though I did find one corrupted symlink on the disk, and an ls -ia . in the containing directory showed it with question marks instead of the usual properties, it had no inode and couldn't be deleted from the drive (I tried mounting the disk on Linux as rw using https://github.com/linux-apfs/linux-apfs-rw, hoping that I may be able to remove the file, but to no avail).

The only solution is to run a fsck which brings us back to the start, so no luck with that. Unfortunately, I couldn't find a fsck for APFS available on Linux right now so I had to reformat my disk.

I'm having this 49218 problem for the second time with a WD Elements 5TB drive as a Time Machine backup for an M1 MBP running Monterey 12.6. I returned the first WD drive in December as defective but now I see it might be the OS.

The problem has been there (for me) since before Catalina. I changed a drive for a higher capacity one, and now have it slaved with an enclosure. Any time there is the slightest physical disturbance to the drive, there is a report of having unmounted the drive without ejection. Subsequently, the drive gives the error message "com.apple.DiskManagement.disenter error 49218". I keep the drive in the hope that one day, Apple will look at the problem! I am not holding my breath.

Hello, I am using translator.

I already know how to recover the files, enabling reading and writing for disks in non-fat32 format with encryption and that is to connect it in my case to 1 ipad (in my case ipad pro 12.9" 4th generation) and then enter the key in the app "Files" and that's it, you can download everything to the ipad (files) and then from the ipad to macbook or etc.

PS: But it still can't erase the drive for other devices to recognize it.

ready now everything on the hard drive is recovered, now take the hard drive to windows where I erase the drive and then take it to my macbook and give it the desired format AND READY ALL SOLVED, ALL THE INFORMATION HAS BEEN RECOVERED AND ALSO THE DISC HAS BEEN RECOVERED.

Fixed - Partitioning worked. I have a 1TB WD drive that I use to back up the Mac. I partitioned 999GB and it was able to delete the drive. All other options didn't work.

I have the same, and none of the above helped me.

I need to access the files in it, does anyone have other ideas?

in my case

1. Macbook with Catalina 10.15.6 mount the (49218) SANDISK 4tb without problems, from here you can transfer the files to another disk.
2. Ipad Pro Gen 4 mount the Disk

I am using a translator.

Same problem. MacBook Pro 13-inch, 2019 macOS Ventura 13.2 External HDD 2TB, APFS formatted. I don’t have an iPad.

Show All Devices in View of Disk Utility menu. Right-click the container disk of the HDD that could not be mounted. I was able to rescue the data by creating an image from ”Container disk”. This method requires another HDD or SSD

**MacOS ventura 13.3.1 has fixed it!! I am very happy! **

I have the same problem. For mine I noticed if I wake the computer before the ssd wakes up I get the error. If I bump the mouse before opening my laptop it wakes up the ssd and then I open my Mac. I forgot to do that this afternoon though, and I forgot how I fixed it last time. Does anyone have a solution for this? I need to access documents on this drive for a class and I cannot for a simple silly reason. Th ssd never unmounted it just went to sleep with the computer. So frustrating.

I used these steps to erase the drive and restore it to "factory":

1. menu: View / All Devices
2. select the parent of the damaged volume (in my case, "WDC WDS5 somelongserialnumber Media")
3. Erase

Note that this absolutely will wipe the contents of the drive. Not a big deal for me, it's just a Time Machine. If you need to recover your data, you'll probably need a tool like Disk Drill

What you're seeing in that tree is a representation of first, the physical media (you'll see the topmost says Apple SSD Media), then an APFS Container (an abstraction that lets the file system do some neat tricks with drive partitions), and then your actual partition. What I believe is happening is that the container was somehow damaged, so erasing the partition doesn't help, you have to go all the way to the physical media and wipe everything.

If you do want to recover some data, I would suggest…

1. menu / View All Devices
2. run First Aid on the container, and if that fails, the physical media.

Hi everyone! I found a way that helped me solve this problem, I'm happy and want to share with you. First you need to go to the Terminal and enter the command diskutil list. Then find the hard drive you want to be repaired. It will be something like /dev/disk5. You need to remember this name. After that, restart the Mac and start it in recovery mode using the Cmd + R. then go to the Window - Terminal. Enter following command /sbin/fsck_apfs -fy /dev/disk5. Where instead of apfs you need to write the name of your file system and instead of /dev/disk5 the name of your hard drive. Then the restoration of your file system and the elimination of errors will start. In all cases, write yes to eliminate errors. All! restart your mac and you're done. This helped me to access the disk without data loss. I hope this will be helpful to you.

Hey everyone. Just wondering if anyone’s ever dealt with a hard disk not mounting with Diskmanagement.disenter error 49218 ?

I’m running a 112TB Symply SPARK (an 8-bay Thunderbolt 3 RAID system with RAID 5 configuration, formatted APFS to 98TB), and since updating macOS from 13.5.1 to 13.5.2, the disk no longer mounts and first aid can’t repair it.

I’m on a 16” MacBook Pro M2 Max. I’m desperate to rescue/recover the data on the unit, any thoughts? Thanks all 🙏
