Mx500 2tb showing 121GB capacity?

A little techy, but need help. Just installed the MX500 2TB in my 27” iMac late 2012, erased to format, reinstalled OS Mojave.

When I check the disk, it is only showing a total capacity of 121GB. I tried formatting again with the same result.

Anything else to try? Thanks!!

Run DriveDX and select your SSD on the left pane.  Please post a screenshot of this page which contains information about the general information of the SSD and a summary of the health indicators.

Should I also be concerned with the wear issue? It’s a new SSD.

Sorry, the moderators haven't approved your screenshot yet.   There is a way to create a text report from DriveDX which you can post here as well.

The screenshot shows an Apple 128GB SSD who's life & health are deteriorating most likely due to a large number of writes and perhaps a drive that is out of space.   I'm curious to see a screenshot of all of this drive's "Health Indicators" or you can save/export the whole report which may provide even more information about this Apple SSD.

 

How & where did you install the MX500?  Is it sharing a connection with the Apple SSD or did you install the drive in the Optical drive bay?  Is the MX500 connected externally?  If so what adapter is being used?

Re: Mx500 2tb showing 121GB capacity?

Embarrassingly I just discovered my iMac has the Fusion drive, and the SSD wasn’t being read (installed to replace the old SATA HDD.)

I have now tested the SSD connecting to another computer and I seem to have fixed the connection error. Assuming it will work once I install it back into the iMac.

Thanks for the help!
