I infer that Seagate generally doesn't disclose problems or even fixes. You have to report a problem to support, and perhaps even ask explicitly for a firmware update to be offered one. Note: messages on the Seagate forum are for user to user communication and support people apparently never read them! There are Seagate moderators but they are not technical and are not support. The one exception is the particular firmware update that prevents the bricking of 7200.11 drives. They announced that fix and made the firmware available for download. My guess is that they released it because the recovery from bricking is painful to Seagate: once it happens, any normal user must RMA the drive. I, for example, asked for and got a firmware update in mid January to fix a performance problem with my ST31500343AS. This firmware was not announced, but I asked for it because I knew it existed. This was just before the bricking problem was announced. The firmware I got was not the unbricking firmware. There is much confusion on the Seagate forum. Many users think that the released firmware is supposed the fix their particular problem. In fact, it was released to fix one particular bug. It might happen to fix other bugs (because it was based on later firmware than their drive came with), but that was not the point. Seagate has leaked, but not announced, details of the bug fixed by that firmware. Amazingly, some users have figured out how to revive a bricked drive using a serial diagnostic console. http://www.msfn.org/board/index.php?showtopic=128807 If you have a lot of time on your hands, it might be interesting to see what the serial diagnostic console has to say when your drive is misbehaving. | There was some | other guy with the same model and same firmware that also noticed the | drive locking up once in a while.

D. Hugh Redelmeier h...@mimosa.com writes: Could you dd an equivallent volume from /dev/zero to see if it also causes a problem? That eliminates one more variable from the problem. I'll try. I have only seen it happen with a dvd as source. Disk to disk copies such as cp -ax / /mnt/backup didn't seem to cause problems. Why do you call it streaming conditions? Do you think that the fact that the DVD delivers bytes more slowly than the hard drive would accept them is important? I had assumed that the bug required a high sustained data rate that would dump a large number of consecutive blocks into the disk's on-disk cache, but was still slow enough to allow the on-disk cache to drain. But then again, it was just a stab at explaining why it only seemed to happen when reading from dvd. Or is there some other aspect that you think is relevant? Hard to say. I'd only really had 3 or 4 lockups and each time it was the morning after I'd added a new video. NCQ has been around long enough that I'd expect/hope that the nits have been picked. Of course I could be wrong. Well, I've seen the bug described as a on-disk cache flushing bug and/or NCQ bug. In any case, Seagate support got me some SD3B firmware to load onto the disk. Strangely my disk now identifies itself as ST31500341AS instead of ST31500343AS (with a 1 instead of a 3). That also explains why I couldn't find other folks with bug reports -- only a few drives went out with the trailing 3 model number. Lets see how the drive holds up. I'm beating on it right now. -wolfgang -- Wolfgang S.

After running flawlessly for 6+ months I just had my Seagate ST31500343AS (w. SD35 firmware) flake out. Does this look like the NCQ bug or just a random event? The final error msg was around the time the machine hung hard.
