Sensor bug

1. There are two identical model HDD (WDC WD30EZRX-00DC0B0).
2. They have different serial numbers.
3. I have renamed the HDD temperature sensor labels, one called F_Temp, and the other called V_Temp.

A. After a reboot and HWiNFO restarts, both HDD will be named F_Temp. I have to manually rename the second HDD.
B. HWiNFO does not remember the original name.
C. No such problem for the other brand/model HDDs.
D. Interestingly this bug does not affect the Toshiba DT01ACA300 HDD (there are two of them - T and U)

Maybe the string array length to store the original sensor name is not long enough.

Software Version:
HWiNFO64 6.40-4330

Try to change the name and close HWiNFO before rebooting. You could also try to close and open HWiNFO to verify if the change is saved properly.
I tried to change the name, then close HWiNFO, restart HWiNFO. The name change persist.
I then tried a reboot, and the name change still persist.
Thank you.

I wonder why it did not persist before...
