Help interpreting SMART values

[daisensou]

So I just lost 2 Western Digital 1TB HDDs (WD10EARS and WD10EADS) due to unknown causes. One went dead dead, the other one just nuked my Win7 partition and started arbitrary denying access to the other, data partition. Weird as hell since SMART never indicated anything wrong, they simply suddenly went kaput.

Now I got this Seagate drive and the SMART shows everything as "Green\OK", but it shows some really high numbers for RAW values (all other attributes are at 0 and 1 for High Fly Rates).

What's the meaning of those RAW values? Thanks in advance.

Model: ST31500341AS

Are you referring to the hex data?
Hexadecimal - Wikipedia, the free encyclopedia
It's basically just a basic computer code.
The link should explain it a bit.

I know what Hexadecimal values are, question is, why the discrepancy in the report?
At first I thought they were addresses and not values, but that doesn't explain why every other item is at 0 or at an explainable low value.

For example, "Power-ON Hours Count" presents a RAW value of "1E" (as in, 0000000000-001E) which is about 30 hours of use, it's about right because I got the HDD on Saturday (18) and basically only used it to install\update\configure Windows7.

I'm sorry if I sound a little paranoid, I'm really not in the mood to lose another HDD in such a short period

Unless the drive is a seagate 7200.11 model, I wouldn't be terribly concerned.

Good God, why the hell did you say that!? Hahaha.

Indeed it is, a Seagate 1.5TB 7200.11, ST31500341AS

the 7200.11's had problems early on, I think it's mostly been fixed now.

^^old news article on them.

Have a look at this: S.M.A.R.T. - Wikipedia, the free encyclopedia

@Dwarf

Wikipedia says:

Lower raw value is better

Excuse me gentlemen, I think it's better for me to start pulling an extra image of the Win7 partition, just in case...

Ok, last update on the matter.

Seems like it's normal for Seagate drives to present those high numbers and they do not correspond to the actual health of the drive (although HDDLife is accusing a health of 47% due to those high values).
So confusing ;_;
