Hi,
I have 4 SSDs (WDS250G2X0C)
Percentage Used value = 0% in 3 of them, which have Data Units Written 185TB, 16TB and 12TB respectively.
whereas
Percentage Used value = 29% in the remaining one, which has Data Units Written 59TB.
So only the last one seems to show correct Percentage Used value.
I see that FW Rev for 3 of them is different from the 1 showing correct reading, however it is used on a linux machine so not sure if it can be updated.
Is there a way to fix the Percentage Used reading?
More details:
