Warning su hdtune: Ultra Dma Crc error count!

[giovanni69]

Solo per segnalare che nell'HD in oggetto dei precedenti post, i valori del parametro Raw Read Error Rate continuano a salire:




Effettuando un altro test di 'refresh':




Ed anche anche dopo test distruttivi come l'inizializzazione la superficie del disco è perfetta:



Lo sviluppatore di HD Sentinel ha così commentato il caso:

Yes, to be honest, personally this is what I expected.
While yes, the raw read error rate value increased (sometimes, not in all tests) they seems not indicate actual problems we'd need to worry about.
The intensive tests verified both the read and write capabilities of the drive,
all data sectors overwritten, read back and verified that they can accurately store information.
The tests show no damaged or bad blocks - and even no slower areas (where the blocks would be darker green, indicating that while the sectors could be read/written, they may take longer time than expected and we may see failure / problems later).

So personally I feel currently (or even if the counter increases with 1000-2000 or so) we'd not need to panic: the current counter and the change does not indicate that a warning should be issued. Not only because the "Value" is far from the "Threshold" (as manufacturers can play tricks with these to show even almost dead drive as perfect) but because the intensive tests revealed absolutely no problems: no significant increase of error counter, no change of other (maybe more important) self-monitorig attribute and (most important) no problems with any data sectors, regardless of self-monitoring data at all.

I must tell that you gave an idea about having any custom alerts, for example where it is possible to configure any attribute / number which can trigger an alarm.
So then (for example) you can configure that you want to receive an alarm when this counter reaches 5000, 10000 or so.
I can't promise that it will be available soon, but maybe in a later version - as this may help and give an other level of protection.

Attualmente per precauzione l'HD è diventato di backup per il semplice fatto che ho anche un altro Velociraptor anche se da 150 Gb e non si comporta certo in quel modo circa quel parametro SMART. Quindi, nel dubbio meglio clonare/ backuppare e via!...

Non c' entrano niente gli errori lettura con i Seagate Barracuda .
