Martin said:What values does HWiNFO show for it? Do you see that drive in Device Manager too?
Please also attach the HWiNFO Debug File for analysis.
Martin said:OK, I see now. If you have renamed the labels then the entire custom label you used (including the serial number) is kept for a device at the same address.
Try to rename the label again, it will then show the original (new) serial number.
Martin said:SATA drives can return 2 temperatures, but usually they are the same. So actually it doesn't matter which of those is returned as it mostly reflects just a single temperature sensor.
