Hi,

This is with 2.6.31.1.

I'm having a lot of problems with a lacie external hd[1]. It seems the
actual disk is a seagate ST375064, and the bridge is a JMicron 2339.

In normal usage what I see is that if I don't use the disk after a
while hear a loud click (as if something got stuck) and then I cannot
use it any more; I have to turn it off and on again.

But then I started to see some problems on one fs, so I ran badblocks
and I noticed a lot of strange behavior. It seems once I get a
read/write error then I get more of them in a row, and after a while I
hear another loud click, and then I only get read/write errors
constantly.

I noticed in 'unusual_devs.h' there's already a quirk for another
JMicron product, so I tried to do the same:

+UNUSUAL_DEV(  0x152d, 0x2339, 0x0000, 0xffff,
+               "JMicron",
+               "USB to ATA/ATAPI Bridge",
+               US_SC_DEVICE, US_PR_DEVICE, NULL,
+               US_FL_IGNORE_RESIDUE | US_FL_SANE_SENSE ),

This seemed to help with the consecutive errors, but not with the loud click.

This is what I get when this click happens:

The log shows the device just disconnected from the system.  You should
post more of the logfile before the disconnect so we can see if it's an
issue with the USB core.  Did it work with a previous kernel?

It could be that your disk is just dying, and occasionally
disconnecting.  Or you could have a bad cable or a hub that's
introducing noise.  Can you try a different USB cable?

There was nothing special in the log. I think it was completely silent
for a while. I'll grab more logs and post them.

I'm not sure if it was working properly on previous kernels. If it
did, it was probably a long time ago. I least I can remember this
behavior since .28.

I already tried with a different cable. Another external drive I have,
worked perfectly (badblocks didn't return a single bad one) with both
cables.

This sounds very much like a hardware problem, either in the drive or
in the bridge chip.  There's no direct way to tell which; you would
have to try attaching the drive to a different chip or the chip to a
different drive.

The two places where your listings showed the Serial number (the kernel
log and the /sys/kernel/debug/usb/devices file) have different values,
suggesting that the chip is at fault.  But this isn't definitive.

I'm not sure I can do that. There doesn't seem to be any way to open
the device and I don't have a way to test neither the disk, nor the
bridge. I would like to leave that as last option.

The first reported serial number seems to be correct, but the second
one (after the click) isn't.

Anyway, what about all the errors before the loud click? Couldn't it
be that the driver is causing the device to malfunction? At least the
patch seems to decrease the number of reported bad blocks. Once
applying the patch the first block of bad blocks is always the same,
but the second is always different, then the click happens.

I'm attaching the full log.

Then it doesn't really matter whether the problem is in the drive or in
the chip, since separating them is impractical.

I doubt that very much.  And besides, if the device were designed
properly then it wouldn't malfunction, no matter what the driver did.

A usbmon trace would contain more information.  We could see the exact
sequence of commands and error codes.  I'm not sure it would help solve
anything, though.

You could try plugging the device into a different computer and see if 
it behaves the same way.  If it does, your best course might be to 
exchange it for something that works better.

Not in my particular case, but if it turns out to be some kind of
hardware defect then we know other people would not be affected.

Indeed, but I guess there's a reason you have a quirks list: some
devices are not designed properly.

I followed the tutorial and the resulting log is 73M long. I don't
know what I'm looking for, so there it is:
http://people.freedesktop.org/~felipec/1.mon.out

I'll try to do that, but it might take me a while to find one that
doesn't run Linux.

Thanks for the help so far.

Can you take a look? Is there anything else I can provide?

Unforunately the usbmon trace isn't much help.  It shows several 
unrecovered read errors, but you already know that the disk has a bunch 
of bad sectors.

Then near the end, for no apparent reason, it shows a failure right in 
the middle of a READ command.  The computer tried to read 128 sectors;
the drive sent back 48 sectors of data and then stopped responding.  
Something in the firmware crashed; my guess is that the bridge chip 
failed.
