Hi guys,

I recently bought couple of 3TB Seagate ST300DM001 drives and ran burn-in test using Linux command "badblocks -wvs" that fills entire drive with data and tries to read it back, it does it 4 times with different patterns. It didn't report any errors, however I am concerned about few things after checking SMART data.

Few concerns:

- Raw_Read_Error_Rate is high, my SMART app says values over 0 indicate a problem
- Seek_Error_Rate also somewhat high
- drive A took 41h:45m to complete test, drive B was slower with 43h:15m, to write and read 12TB

Is this normal or I am worrying for nothing? I don't quite trust Seagate, hearing about high failure rates, hence this post.

Thanks!

The raw values for those attributes are sector counts, not error counts. Everything looks OK to me.

See http://www.users.on....R_RRER_HEC.html

quoting from that link: "Seagate's SMART documentation is not publicly available. The following information has not been gleaned from any official source, but is based on my own testing and observation, and on testing by others. Therefore it may contain errors. "


Yet another reason to avoid Seagate.

They are secretive about spindle speeds and number of platters, they sell different products under identical model numbers, and they won't disclose what their Smart info actually means.

It seems they hire their employees from the NSA with a pronounced anal retentive fixation on secrecy.

To be fair, Seagate have until the last couple of years been one of the best companies when it comes to documentation. Twenty years ago they gave me detailed paper technical manuals (books) for free, and they've always had detailed product information in their Product Manuals. Sadly, times have changed ...

And to be fair WD started this "not telling you the number of platters" nonsense. Back in the days the 40 GB WD0400BB (approximately) could have anything from 4 x 10 GB platters to 1/2 x 80 GB in the later models! Doesn't make Seagates inaccurate information any better, but they certainly didn't invent this.

BTW: I used to be a fan of WD, primairly due to their good firmware since the WD0800JB, but this stopped when they stopped building affordable 7.2k drives entirely (no, I'm not interested in buying <= 1 TB).

BTW2: those SMART values seem fine to me as well.

Seagate's old model numbering system would tell you the number of platters in the second-to-last numeric character. Nowadays Seagate tout their "New, Simplified Model Numbers" in a document which they unfortunately refer to as their "Cheat Sheet".
