 Seagate Barracuda drives giving corrupted data - results

Our panel pf experts (thats you out there on the internet :-) and contacts
came up with the following answers

How can you tell what the firmware revision is?

        scsi probe will tell you the drive type, or the answer in format.dat
        (when I formatted the drive)
        e.g. "SEAGATE-ST15150N-0022"
        and the final digits (0022 in this case) are the revision

which version is duff?

another source said:

it also appearrs to be a problem with Solaris, not Sunos

Thanks to everyone who contributed.

If anyone from Seagate reads this:
        How about putting firmware revision information on your web site?
        I didn't find anything useful there http://www.**-**.com/ in
        this matter

Seagate ST312320N-0300's (I think there's an extra digit in that
part number but I don't have it handy) should be updated to 0640.
I saw multiple reports of problems with these drives when used
with Veritas (software RAID for UnixWare and others) but Seagate
claims to know nothing about it.

I think Seagate needs to seriously improve how they get reports
about drive problems and how they make firmware updates available.
If I can find multiple people having a problem and Seagate has
never heard of it [and I think I ended up going through a lot of
people at Seagate, one person visited the factory where that drive
model is made and still could find noone that had heard of my
problem], then Seagate needs to take major steps to make it easier
for this type of information to get to them.

It appears that Seagate wasn't even aware of the problem after I'd
gotten an MS-DOS program from them to update my disks' firmware
because of the problems I was having.

You should also read their firmware change logs.  They pretty
clearly indicate that Seagate does a lot of testing of finished
products but doesn't do enough testing of the software components
(subroutines, modules, etc.) that go into the firmware.  Lots of
boundary cases getting fixed over and over again when someone
finally generates a boundary condition.

But other than the corruption of data and having several disks go
bad almost immediately, I haven't had many problems with them so
far (only a few have started getting media errors or just plain
died).

Seagate did offer to analyze the problem even though the firmware
upgrade appears to have fixed it, but we never got the problem to
happen in the lab so I'm pretty sure they dropped it.  Which might
mean that you could ask Seagate about it and they still won't know
anything about (nah, that's unfair, they probably do).
