Same issue with 7.0.0. 64bit with the same exact drive. 09 _99 _99 0 000000000306 Power-On Hours. and it was reading 12 hours. HWInfo 64 reads 774 hrs. So, I erased the .ini and let it regenerate it. Now it read 774 hrs as well.
In the ini that was causing the problem, there's a long list of drives PowerOnUnit and a line that reads TOSHIBA MQ01ABD100(S/N REMOVED...)=2 I am not sure how that got on there.

CrystalDiskInfo Ver.9 will support to customize Power-on Hours unit.
Version 6.5.2 x64 reports power on hours for Toshiba MQ01ABD100 1000.2 gb hdd as 73238 hours. The 32 bit version of crystal diskinfo reports the correct number of power on hours as 1220. the hex value for power on hours is x'000000011E16'. Again 32 bit version ok, 64 bit not ok. contact achousman@gmail.com. thanks
