I just bought the Sandisk Extreme 2TB SDSSE61-2TOO. If I plug it using the USB-C cable that came with the SSD in the box into my 2021 M1 Max MacBook Pro 16", I can see the Portable External SSD in About This Mac/Overview/System Report/USB. But I cannot see it in Disk Utility. I get the same results if I restart, if I use al the USB-C ports on my MacBook Pro. Is there anything else I can do? Thanks.
Hi @rtsy,
Please refer to the instructions mentioned in the below articles and let us know if the issue is resolved:
Title: Windows Or macOS Cannot Find My Drive (Drive is not detected by host system):

1. Check and set Finder Preferences and make external SSD show up in Finder
Go to Finder > Preferences > General tab, then tick the “External disks”
Then, go to the Sidebar tab, and tick “External disks” under “Locations” to show the hard drive in the Finder sidebar.
2. Force quit fsck in Activity Monitor
Click the Launchpad > find the Other folder > open Activity Monitor.
Search in Activity Monitor to see if there is any process named “fsck_hfs” or something like that. (If your external hard drive is FAT32 formatted, then it should be “fsck_fat32”.)
Select that task and click the X button to force quit it. and Then your SSD should appear on your Mac.
If the SSD still won’t show up in Disk Utility, try update your macOS to a newer version (right-click the Apple logo > choose System Preferences > find and open Software Update to check for new macOS updates).
