Apple Error 2009

[Barb Frison]

Im having a little issue with mounting my external hard drive lately. I've tried quite a few methods in hope of getting it to work again, but so far, no luck. I hope someone can help me solve this issue, or those who have the same problem may also share your insights.

My external hard drive was working fine about a week ago. But one day, I ejected the hard drive and the icon disappeared, so I thought it was safe to unplug it. When I did, it said the hard drive was not properly removed. It still works fine when I use it the next day, but the same thing happened. It said the drive was not properly removed after I ejected the drive, waited for the icon to disappear, and then unplugged the drive. After that, it never works again, and the attached images are the info I got when I tried to mount or run first aid on this drive.

I had this happen 4 TB WD My Passport on Big Sur 11.6.2, the 1 TB partition for my Time Machine didn't come up and mounting gave the "disenter error 49218". Here's what worked for me (at least for now):

I opened Disk Utility and run first aid on it and got an error (com.apple.DiskManagement.disenter error -119930878.) but after I closed it, it continued running and some minutes later, the drive was fixed and I was able to see it in Finder and use it again.

I unplugged an external HDD without ejecting it first, then had error 49218 when trying to mount it. Surprisingly First Aid didn't show any errors, but still I couldn't mount it. Restarting the MacBook helped, it just automounted. I'm on Big Sur.

Ok, I had this same issue and found a fix. However, it's ONLY a fix if you do not care about what is on the external HDD. Open Disk Utility and hit Partition. Change it to APFS (Encrypted). I hit "Apply" and it warned me that all data would be deleted. I said ok. It wiped it and then it automatically mounted and all is well now.

FIXED!I've had trouble accessing my external LaCie time machine drive for a while now and nothing I had found online has helped. Couldn't mount it, erase it or use first aid on it. Would get failed messages non stop.The only solution that has helped I have, fortunately, found was by this guy on youtube, =Z9y1oRYlmh0. Formatting the container within the disk utility to a MAC OS Journaled had worked and I was able to access the partition anew and then restart the time machine.

I'm having the same problem with my MacBook Pro M1 max. I have a 2TB external drive I was using with Time machine backups that I can No longer mount. Even disk utility won't allow the disk to be erased and reformatted. I would have thought that apple would have the solution by now seeing how so many have encountered this problem. can someone please help????

I had the same issue - I plugged in the USB drive and one volume of three on the physical drive wouldn't mount, giving error 49218. MBP mid-2014 with Big Sur 11.6.8. Like some others, restarting my Mac (with the drive still attached - not sure this is relevant) brought them all back.

Anyways, if your disk happens to be ExFAT, and you remember improperly removing the disk the last time you used it, chances are, fsck is holding it hostage (metaphorically, of course). fsck is trying to repair the disk, but it will stall forever, so you want to launch Disk Utility, and the Terminal. Try to mount the disk, and switch to Terminal and write sudo pkill -f fsck. The disk will mount in read-only mode, and from there, you can repair it with First Aid in Disk Utility. This won't work for non-ExFat drives, as macOS manages them differently.

This happened for me on a Big Sur MacOS, clicking the 'First Aid' option in Disk Utility kept giving me this same error. What ended up working for me was restarting my laptop, then continuously trying 'First Aid' until one time it suddenly didn't give me the error, and after waiting about 20minutes the drive mounted properly. I don't think I did anything differently other than trying over and over again.

This still isn't working for me. I don't understand what this "and the Terminal" means. When I try to mount my drive, the error that is the title of the forum comes up and it appears I am at a dead end. I tried to repair the drive, and it seemed to do something (with a bunch of green check marks) saying it was fixed, but it still won't open or be recognized by my finder or desktop. If anyone is able to walk me through this, I would be very appreciative.

This time, though, even after running First Aid in Disk Utility, the drive is still registering as Read-Only, which I'm not sure how to fix! Anyone have any suggestions or have experience with this? The drive does have about 1.5 TB of data on it, and it hasn't completely backed up to my cloud storage yet, so ideally not anything that requires reformatting (fingers crossed)

The quickest way to sort out problematic exfat drives I've found is to mount them in a windows environment (either in a virtual machine or on actual windows computer) and repair them from there. Disk first aid takes a loooong time on larger drives.

Thankyou @jkrosado and @calif94577. It worked out but without hitting the enter button, magic! Also the exfat formatted LA CIE 5GB drive worked on BigSur before then after upgrading to Monterrey it didn't show up.

I tried that command on the Terminal, the 'First Aid' option on Disk Utility said everything was OK and then same Could not mount drive error, I restarted , tried it few times, same error. Dont ask me why but what worked was Logging Out my Mac user and logging again with the same user, super weird. There's defo some bug on Monterey and the external drives / Time Capsule Mac application...

Hi everyone! I have followed the steps and Disk Utility is running first AID. I have got a SEAGATE 2TB ExFat formatted...but first AID is running "Checking file system hierarchy." and it has done so for 24 hours...is that normal for a 2TB? I am tempted to quit it....

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..

The tip about the target keychain really saved my bacon. I was trying to get the Root Certificates for Charles Proxy installed and only received error code -25294 when using its default "Help -> SSL -> Install Charles Root Certificate" option. I then exported the root certificate as a PEM file and tried importing it manually and got the same error. Upon reading this post, I realised there was a almost hidden option I had not taken into account:

I understand that I may be three years late in responding. But I encountered the same problem. And I found it to be a trust issue. You just need to go to your certificates collection page and double-click on the untrusted certificate to edit the trust settings to be able to use it normally.

I keep looking for a comprehensive list of all error codes sorted by number. If, for example, something reports an error like "An error of type -1409 has occurred.", it seems there must be a list somewhere of descriptions of errors of type -1409. Is there? Does such a list exist?

Both of them contain some intriguing links at the bottom, but the two links that would have included the error code number that I am looking for (-1409) both link to the apple.com site's home page. Evidently, Apple employees have pulled Knowledge Base articles numbered 9804 and 9806 but, rather than give us a 404-Not Found error, missing links simply lead back to their home page.

Did you notice the e-mail link at the bottom of the list I posted to you. Perhaps you could write to him and ask. As he said, the list is never up to date but that's also to say that perhaps he infrequently updates it. Thanks for the star.

I tried Googling "An error of type -1409 has occurred." It got a large number of hits; however most were of the form "Try this and see whether it goes away." In other words, no definition. Then I found one thread where a Senior Member posted a definition without attribution...

The info we have on this error means that some part of the OS is damaged or missing, (assuming that the HD directories & such aren't messed up). Try reinstalling the last big combo update from Apple. It's possible that you will have to do an "Archive & Install" to repair your system files.

Now we're getting somewhere, but where did he get that definition? The source seems to be a 2010 message on the Adobe Reader Bulletin Board. The contributor's email is marked "private" and it's not obvious how to reach him or her.

What if you don't know the framework? Do you have a technique for searching by number (e.g., -1409) to find the framework that contains the corresponding errors.h file? Simply putting "-1409" into the search field of a Finder window doesn't work; it gets "more than 10,000" hits.

This is what makes Mark's technique so interesting. Frameworks are filed by OS Version (I think), so, if you get multiple definitions for the same number, you can figure out which one pertains by scrutinizing the paths to where each definition is stored.

Due to that it gives me another error which is The Application couldn't be verified from Xcode at Runtime when i run it on my iPhone , and thats why because the app was installed already, so I've delete it and run the project from xCode and it works well.

Of course, the error includes the entire stack dump, but I've not included that for sake of brevity. I'm hoping that someone will know what "exit code 254" is. Tried searching for it but couldn't find anything.

UPDATESo I noticed that the dump refers to specific lines on code in a specific class (SCheckBox.m).It's in an init method. I've checked over the method but could not find anything wrong with it. However, if I comment everything inside the method out and return nil, the code compiles. I went through and uncommented every line until I got the error. The error causing the problem is this:
