Details

Shown values of "Total Host Writes" and "Total Host Reads" are too higher than expected.

TBW of 256 GB version of SanDisk X400 is 80 TB.

Dashboard (SanDisk software) reports health 92%.

CrystalDiskInfo shows 1681577 GB written. It is 21 times higher than life endurance.

I have discovered that value of F1 is increased by 64 for every 1 GB written.

See attached screenshots.

The value of AD parameter is probably Life Remaining.

Values in the SanDisk Dashboard match the value of AD parameter. Verified for two disks.

I may fix "Total Host Writes" and "Total Host Reads" problem. Sorry, I cannot add health status support currently.

Please test beta version. https://crystalmark.info/download/zz/CrystalDiskInfo8_16_5.zip

Thank you for testing it. We have identified the cause of the problem, but it will take some time to fix it. We will create a test version soon.
