Subject: [Bug 12240] New: Disk errors sometimes ignored from the USB-SCSI layer
Date: Tue, 16 Dec 2008 13:14:52 -0800 (PST) [thread overview]
Message-ID: <bug-12240-11613@http.bugzilla.kernel.org/> (raw)
http://bugzilla.kernel.org/show_bug.cgi?id=12240
Summary: Disk errors sometimes ignored from the USB-SCSI layer
Product: SCSI Drivers
Version: 2.5
KernelVersion: 2.6.28-rc8
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: scsi_drivers-other@kernel-bugs.osdl.org
ReportedBy: kernel@roestock.demon.co.uk
Latest working kernel version: Unknown
Earliest failing kernel version: pre 2.6.19
Distribution: gentoo
Hardware Environment: x86
Software Environment:
Problem Description:
I have a failing disk drive, and in one type of USB-IDE adaptor bad sectors are
not being handled correctly. This is probably becasue the USB-IDE converter
doesn't seem to report errors from reading bad sectors in the "proper" way, but
it does give plenty of evidence that something is wrong and that the sector
cannot be read.
Alan Stern gave a nice summary here:
http://marc.info/?l=linux-scsi&m=122903295704381&w=2
Various recent kernels seem to do different things when attempting
to read the bad disk:
- 2.6.26 read the whole disk without reporting errors
- 2.6.27 gets in a very long (or possibly infinite) loop
- 2.6.28 gets a bit stuck on the bad sectors, taking several minutes to
timeout, and still does not report error
Steps to reproduce:
Attempt to read bad sectors from a disk drive via a newlink IDE/SATA to USB
disk adaptor.
