Public bug reported:
[Summary]
Copying a specific file from the USB hard drive results in the copy hanging and
repeating "No Sense" messages in the log. Probably not a unusual_devs.h
FIX_CAPACITY issue. The installed system is Ubuntu 8.10, but problem also
present on Jaunty Beta live CD and 8.10 with kernel 2.6.29.
[Steps to reproduce]
Two alternatives:
1) There is one specific file on the drive causing this to happen. Copy that
file from the USB hard drive to the PC hard drive.
2) sudo e2fsck -c -k -v /dev/sdb1
The operation hangs and log messages start to appear when the copy is almost
finished or when e2fsck -c has completed about 30%.

[Test 1 - kernel 2.6.24-21]
Tried the same with kernel 2.6.24-21 and got the same log message, but now only
once, and the file copy and e2fsck -c operations finishes without errors.

[Test 2 - kernel 2.6.29-020629]
I installed kernel 2.6.29 from http://kernel.ubuntu.com/~kernel-ppa/ because
this kernel has the ability to set some Quirks for the USB storage device.
>From http://www.kernel.org/doc/Documentation/kernel-parameters.txt documents:
usb-storage.quirks=
c = FIX_CAPACITY (decrease the reported device capacity by one sector)
sudo modprobe -r usb-storage
sudo modprobe usb-storage quirks=1058:0901:c
I checked that the FIX_CAPACITY quirk was present in /proc/scsi/usb-
storage/2.
The problem was still present.
[Possible duplicates]
I have found Bug #264789 and a lot of reports of "No Sense" messages, but most
of these seems to be related to problems mounting because of incorrect number
of sectors reported by the disk. The fix for these other issues seems to be to
add a FIX_CAPACITY flag to usb/storage/unusual_devs.h. Since adding the
FIX_CAPACITY quirk in kernel 2.6.29-020629-generic did not fix the problem, I
report this as a separate bug.
