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@xxxxxxxxxxxxxxxxxxxx ReportedBy: kernel@xxxxxxxxxxxxxxxxxxxx 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. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
