Now, the Q is: what do the numbers mean? Seconds? Milliseconds? If it's
seconds, the "RAW_VALUE" may explain why all is OK after things have
been powered up long enough. If it's ms, I can only thing it is running
a self-test. I would have to go read those articles more closely to see
what I can determine.
Hi William,
The attribute names (as listed in the "ATTRIBUTE_NAME" column) are
described here:
http://en.wikipedia.org/wiki/Self-Monitoring%2C_Analysis%2C_and_Reporting_Technology
The VALUE column contains a normalized value for the attribute, WORST
contains the drives lifetime minimum (or maximum value), THRESH contains
the drive manufactures failure threshold, and RAW_VALUE contains a 6-byte
value that is used to store the attributes raw value. I see that several
sectors are marked as unreadable in the logfiles you posted. What
do you see in the column "Reallocated_Sector_Ct?" If the SMART attributes
check out, the disk is most likely fine (you can manually run a long self
test to be sure), and I would start looking at the SATA controller ( most
likely culprit) and the SATA device driver (you could easily integrate
some debugging data into the driver to assist with debugging the
problem).
Hope this helps,
- Ryan
