How do I calculate the C5 values of different hard disks from the attribute values of ATA_SMART_INFO?

[lwei2]

For example,The specific code is as follows. How to directly calculate the value of SmartC5 through Raw values? /////////////////////////////////////////////////////////////////////////////////////////////////// int i, SMARTC5 = 0; for (i = 0; i < vars.AttributeCount; i++) { if (vars.Attribute[i].Id == 0xC5) break; }

if (vars.DiskVendorId == SSD_VENDOR_SANDFORCE)
{
	SMARTC5 =
		((UINT64)vars.Attribute[i].Reserved << 48) +
		((UINT64)vars.Attribute[i].RawValue[5] << 40) +
		((UINT64)vars.Attribute[i].RawValue[4] << 32) +
		((UINT64)vars.Attribute[i].RawValue[3] << 24) +
		((UINT64)vars.Attribute[i].RawValue[2] << 16) +
		((UINT64)vars.Attribute[i].RawValue[1] << 8) +
		(UINT64)vars.Attribute[i].RawValue[0];
}
else if (vars.DiskVendorId == SSD_VENDOR_JMICRON && vars.IsRawValues8)
{
	SMARTC5 =
		((UINT64)vars.Attribute[i].Reserved << 56) +
		((UINT64)vars.Attribute[i].RawValue[5] << 48) +
		((UINT64)vars.Attribute[i].RawValue[4] << 40) +
		((UINT64)vars.Attribute[i].RawValue[3] << 32) +
		((UINT64)vars.Attribute[i].RawValue[2] << 24) +
		((UINT64)vars.Attribute[i].RawValue[1] << 16) +
		((UINT64)vars.Attribute[i].RawValue[0] << 8) +
		(UINT64)vars.Attribute[i].WorstValue;
}

Try enabling the "10 [DEC]" in Function - Advanced Features - Raw Values, you may get a surprise. You may manually calculate it by like Windows 10 Calculator's Program Mode, but it is cumbersome, not recommended.

Thank you. In general, how is the value of Smart C5 calculated?

I am not sure about the device and format. It is 0 for most normal devices.
