and do the values display as billions or roll over at 999 million?

I have no idea where that comes from.

Rae Read Error Rate & Reallocated Sector Count was
160,374,848
now is
49,678,669
so looks like it rolls over at 999,999,999

I don't think you meant "Reallocated Sector Count". That figure grows
until the drive fails.

As for the "Raw Read Error Rate", it's difficult to understand how
Seagate uses this attribute. Seagate's FAQ states that ...

"The SMART values that might be read out by third-party SMART software
are not based on how the values may be used within the Seagate hard
drives. Seagate does not provide support for software programs that
claim to read individual SMART attributes and thresholds.

The individual attributes and threshold values are proprietary and we
do not offer a utility that will read out the values."

The "Seek Error Rate" value is also a strange one.

What "Seek Error Rate".
What exactly did you not understand in the lines from Seagate that you just quoted?

My testing suggests that it reflects a seek count, not an error, and not a rate:

However, if I look at the raw *totals* I get ...

http://www.users.on.net/~fzabkar/SmartUDM/13GB.RPT

Seek Error Rate 052E0E3000ECh
Power On Hours Count 0000000026C7h

If I divide "power on hours" by the "seek error rate" (aka seek count ???), ...

http://www.google.com/search?hl=en&q=0x26c7+%2F+0x52E0E3000EC+hours+in+microseconds&btnG=Search

... then I get 6.3 microseconds per seek, which seems absurd.

Let me give you some reflection on that, here is what Seagate writes:

"The SMART values that might be read out by third-party SMART
software are not based on how the values may be used within the Seagate
hard drives. Seagate does not provide support for software programs
that claim to read individual SMART attributes and thresholds."

Maybe you should read it sometime in between when you
are not occupied by your Franc Zabkar promotion.


Here is a spreadsheet of the last 3 month's of SMART data for my
failing 13GB Seagate hard drive:

Dude, that was so interesting.
