CrystalDiskInfo: lifetime reads/writes missing for HDD

Open | Software

I have an old HDD (WDC WD7501AALS-00E8B0) I'm trying to calculate the annualized workload for. Per some articles I've read online, I should be able to use CrystalDiskInfo to get the Lifetime Reads and Lifetime Writes, and then use a simple formula to calculate the annualized workload. The problem is that CDI doesn't seem to show that information anywhere:

Is this information just not tracked for this particular HDD?
