New SSD Shown in System Report but Not in Disk Utility

General
1

I bought a new SSD 2 months ago. It worked fine at first, then suddenly it wouldn’t show up consistently in Disk Utility. Opening System Report, I can see that the SSD is connected to the Thunderbolt port. So it’s connected, but somehow Disk Utility couldn’t find it.

System Report checks the hardware level of the drive’s connection and physical characteristics, such as connection type. But Disk Utility focuses on the logical and file-system level.

I suspect one of the following things:

  • Your SSD is corrupted, although it is new.
  • Your cable or port is not properly connected.

Consider plugging in your drive with a different USB cable. Once you can access the files, copy everything to another disk, then reformat it.

The most straightforward solution is to contact the manufacturer and get a replacement.
