Subject: Annoying problems with lacie external hd (JMicron 0x2339?)

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:
