I have some Seagate Barracuda 7200.11 ST31500341AS 1.5TB drives. They
use the firmware SD17.
They time out at the flush write cache and sometimes on the identify
command.
I know that sounds suspicious so I wrote to seagate but they told me my
drives are ok. (Although I dont think so.)
This drive+fw is blacklisted in the kernel, but there is no firmware
upgrade for these drives. (Only very few serial numbers are able to
upgrade.)
Now I want to know after what period of the time the kernel timeouts at
these commands!? And if this timeout can be increased (manually, small
patch for the kernel) and the min/max/avg time could somehow be
messured. Every timeout kicks the drives off the raid, so I disabled
the write cache (hdparm -W0 /dev/sdx) but thats no solution, just a bad
workaround.
Its a amd64 system with the 2.6.29.4 on an AM3 board with AMDs 790GX +
SB750 Chipsets running in ahci mode.
Thanks for your time and support!

I think you might have tried the wrong firmware file.
ST31500341AS needs

HTH,

I tried that one (compared md5sum). It does not work. It only works
for "ST31500341AS, 9JU138-300 or -336, SD15 through SD1A ONLY!"
So the utility fails and says the specific model could not be found.

Did you try to contact them?

I believe the timeout for commands like these is usually 30 seconds.
Normally if it doesn't respond after that length of time, it never will.
Even if it eventually did, I don't think you'd be happy with disk access
delays of over 30 seconds..
Of course I did. They told me, my drives are not affected and drives
with "good" serial numbers will not be upgraded.
And they now told me I have OEM drives (???) which they do not provide
firmware upgrades for, although my drives are ok. I dont understand
those support-people.

Ok thats definitly bad. Will reask at the support...

Well, they might be right. Or the drives may be affected but they don't
support OEM versions anyway and may not know.
Obviously one could try updating anyway (I'm sure a simple hack in
version/SN checking routine would do). It may be risky.
You should, in theory, contact the OEM partner, not the manufacturer.
Could be hard.
OTOH I think the update fixes unrelated problem (a drives failing to
start), that would need checking.
