Comment 32 for bug 1366538

I use a Maxtor OneTouch 250GB, and can confirm the previous reports:
even an fsck that returns "clean" (ext3 partition inside) is followed by 2 errors like:

end_request: critical target error, dev sdX, sector 0

Any subsequent fsck turns off the journal and finds many previously non existent errors.
All consistent with the diagnose and explanations given (see dmesg log below).

(Can't run smartmontools nor hdparm, "unsupported USB bridge").

Tried with all trusty linux-image updates since 3.13.0-35, even linux-image-generic-lts-utopic
(3.16.0.31.24) . All have this bug.

Reinstalled 3.13.0-34 just to be able to use this drive. It's really unfortunate that kernel maintainers refuse to fix this; seems my Ubuntus are stuck with this version 3.13.0-34 then.

Relevant dmesg:
