To se mi nejak nezda, ten prepocet. Napriklad v jednom serveru mam

Model Family:     Western Digital RE3 Serial ATA
Device Model:     WDC WD5002ABYS-18B1B0

a kdyz dam smartctl -x /dev/sda, tak mi to ohledne teploty vypise:

 ID# ATTRIBUTE_NAME          FLAGS    VALUE WORST THRESH FAIL RAW_VALUE
 194 Temperature_Celsius     -O---K   110   105   000    -    37

coz se mi zda uz nevychazi
ve vypisu o kousek dal je:

Moc me hlava nebere, proc je Power Cycle Min < Lifetime    Min. To je
nejake podezrele. Zajimave jsou ty doporucene a maximalni rozsahy
teplot.
