Grazie mille per la riposta alecomputer....
Per il momento ho effettuato un test, durato circa 2 ore, con il tool di HP presente (credo) nel bios, e il risultato è questo:
Poi ho anche fatto una analisi veloce con SpeedFan, che nella sezione S.M.A.R.T. mi dà questo:
"Your hard disk is a Hitachi HTS727550A9E364 with firmware JF3OA0E0.
The average temperature for this hard disk model is 37°C (min=25°C max=51°C) and yours is 37°C.
All the attributes of your hard disk are above the S.M.A.R.T. thresholds set by the manufacturer. This is good.
NOTE : your hard disk Power On Hours Count attribute current value (95) is below the normal range (98 - 100) reported for your specific hard disk model. Basically your hard disk was powered on for more than the maximum time the average user did. This means that either all of the reports collected are from hard disks that were not powered on for too long (this is realistic for recent models) or that your hard disk is becoming old. Usually this is not considered as a pre-failure advisory, but you should check whether you want to replace the hardware or keep an eye on its performances over time.
WARNING : your hard disk Ultra DMA CRC Error Rate attribute current value (98) is below the normal range (98 - $issue.params[2]) reported for your specific hard disk model. This usually means that some communication errors occurred between the hard disk and the external controller. Most likely those errors are due to the cable. Double check it, reroute it and, if needed, replace it.
NOTE : your hard disk Power Cycle Count attribute current value (99) is below the normal range (100 - 100) reported for your specific hard disk model. Basically your hard disk was power cycled more times than the maximum number the average hard disk was. Power cycles put some stress on the hard disk mechanic. Sometimes power cycles can be caused by a loose hard disk power connector. Make sure it is properly fastened.
The overall fitness for this drive is 98%.
The overall performance for this drive is 88%."
Come mai credi sia un problema dell'hard disk?! Perché invece tutti i test che ho fatto, compresi i dati di HD Tune e SpeedFan, mi fanno pensare che possa essere un problema di cavo...
In ogni caso ora provo a cercare il programma diagnostico per il mio disco..
Grazie ancora....
