Re: [opensuse] Re: Interpretation please
Continuing with this top posting, because Linda started it.... ;-)

Is it possible, Linda, you have misinterpret the readings?
See: http://www.linuxjournal.com/node/6983/print


Each Attribute has a six-byte raw value (RAW_VALUE) and a one-byte normalized
value (VALUE). In this case, the raw value stores three
temperatures: the disk's temperature in Celsius (29), plus its lifetime minimum
(23) and maximum (33) values. The format of the raw data is
vendor-specific and not specified by any standard. To track disk reliability,
the disk's firmware converts the raw value to a normalized
value ranging from 1 to 253. If this normalized value is less than or equal to
the threshold (THRESH), the Attribute is said to have failed,
as indicated in the WHEN_FAILED column. The column is empty because none of
these Attributes has failed. The lowest (WORST) normalized value
also is shown; it is the smallest value attained since SMART was enabled on the
disk. The TYPE of the Attribute indicates if Attribute
failure means the device has reached the end of its design life (Old_age) or
it's an impending disk failure (Pre-fail). For example, disk
spin-up time (ID #3) is a prefailure Attribute. If this (or any other prefail
Attribute) fails, disk failure is predicted in less than 24 hours.


That 130billion number is not the count of raw read errors. Its a combination
of temperature, plus lifetime min and maximum values of temperature, and most
of all it is
VENDOR SPECIFIC.

The number you want is in the VALUE column.

Some might regard this as "ok", but I wouldn't.

The Raw Read Error Rate is non-zero, heck over 130billion,

seek error rate doesn't look good,

Total blocks read is less than 3X the correctable read error rate.

Going through a correction for 1/3rd of your blocks seems, AT LEAST,
like it would be slowing things down, and would seem risky.

On a good disk those error rates would be at or near zero.
But your disk is falling back to EDD correction over 1/3rd the time now.
That doesn't sound good to me... but maybe I'm more paranoid.

My motto was at first sign of disk corruption (even correctable), replace
the drive. You don't want to wait till it is "uncorrectable", trust me.

I just ran smartctl on my 2 drives, sda and sdb, with the following results.
Could someone please interpret these results and tell me if
there is cause for worry.

Thanks in advance.

BTW, both drives are Seagate Barracuda 1TB SATA 3 and are 2 years old.
