Please test the current SoftRAID beta. In the SoftRAID log, it should show the details for the predicted failure;

thanks!

Thanks for explain what SoftRAID is flagging the drives for!

We will try to add logging in the SoftRAID Log for the specific reason these drives are flagged as predicted to fail, but they are showing issues. Note the Media and Integrity errors. This means each has had an average of 300,000 events where the media wrote the wrong information to disk. (ECC corrects this, yes) We flag this as a state where the drive is likely to fail soon. Its statistical, not deterministic.

I've included the info for both M.2 SSDs that SoftRAID is listing failure predicted.

I need some data for you. There is a bug in SoftRAID logging for the particular failure mode your drive has. If you can get me some data quick enough, we can fit it into the next SoftRAID update.

If you look at the SoftRAID disk tiles, each disk has a "disk identifier". the predicted to fail disk in the support file was disk15 for example. These numbers change frequently.

Please look at the disk tile for your failing NVMe drive. It may still be disk15, or it may be another number. Below is a terminal command. Replace 15 with the current number of your disk.

Open the terminal.app.

Paste this command in, and hit enter:

softraidtool disk disk15 getsmartdata

copy/paste the text and post it here. thanks!

Save a support file with this versoin and attach it.
