I have an interesting case here. I bought a WD Blue SSD with the Product Number WDS100T2B0A. Usually this shows up as Device Model "WDC WDS100T2B0A". However in this particular drive, manufactured in June 2020, the device model shows up as "SanDisk SSD G5 BICS4". It should be added to the "Marvell based SanDisk SSDs" in drivedb.

Just seen an interesting fact on a hard drive with a current Power_On_Hours value of 65966. I launched an extended offline test (using -t long) and the LifeTime (hours) column does not show the real Power_On_Hours value:

Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

It seems that the maximum Power_On_Hours value is 65535 (interestingly the same value as the maximum network port range). All values above that are shown as difference LifeTime (hours).

Is this a bug? Is this intended?

PS I Used smartctl 6.6 for this.
