Hey guys,
I recently bought a Samsung 8TB QVO drive for hosting sound design and sample libraries for my audio work. The drive had been working fine for the past couple of weeks on my 16" M1 Max running Monterey.
Unfortunately, the drive just won't mount anymore. It shows as greyed out in Disk Utility. I can't seem to run first-aid on it. I get this error,
Checking file system and repairing if necessary and if possible.
Volume is already unmounted.
Performing fsck_hfs -fy -x /dev/rdisk4s2
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…
When I try to mount it, I get an error saying "com.apple.DiskManagement.disenter error 49244"
This seems to be a fairly common issue when I searched for it and more prevalent on the newer OS. None of the fixes worked for me because I had the drive formatted to APFS.
The problem for me surfaced when I ran out of ports to connect the SSD directly to the Mac and ended up using one of my USB hubs and one of the USB-C to USB-A cable from my T5 SSD. This has happened twice over the last 2 days and I just spent the entire day transferring about 5TB of data from my slower drives. The first time, the issue popped up when I tried running a Blackmagic Speedtest on the drive to check whether the hub was running at 10Gbps or 5Gbps. I did eject the drive properly, but how can connecting to a USB Hub screw up the drive? I usually connect my other T5 SSDs to this very same hub. Is it some sort of power delivery issue? My 5TB WD Passport doesn't spin up using this hub.
Not sure what is causing the issue here, but I would like to avoid the issue or find a solution for it. Anyone had a similar error (com.apple.DiskManagement.disenter error 49244) in the past and managed to fix it?
TLDR: Samsung SSD drive becomes unmountable after connecting to a USB Hub giving this error: com.apple.DiskManagement.disenter error 49244
