problem with specific USB drive in new distributions
I have a USB drive that will now longer mount. It still mounts in OpenSuSE 11.0, which is built on kernel 2.6.25, but it will not mount in Ubuntu 8.10 or four other distributions that are built on kernel 2.6.27. All of my other USB devices mount in all the distributions I currently use or have recently tested.
Here is the info for this drive from hwinfo: UDI: /org/freedesktop/Hal/devices/usb_device_4971_a002_8F29E2_if0_scsi_host_0_scsi_device_lun0_scsi_generic Unique ID: CLb3.vQ_wcuH+9uD SysFS ID: /class/block/sdb SysFS BusID: 5:0:0:0 SysFS Device Link: /devices/pci0000:00/0000:00:1d.7/usb7/7-6/7-6.5/7-6.5:1.0/host5/target5:0:0/5:0:0:0 Hardware Class: disk Model: "WDC WD16 00BB-56GUC0" Vendor: usb 0x4971 "WDC WD16" Device: usb 0xa002 "00BB-56GUC0" Revision: "20.0" Serial ID: "8F29E2" Driver: "usb-storage", "sd" Driver Modules: "usb_storage" Device File: /dev/sdb (/dev/sg2) Device Number: block 8:16-8:31 (char 21:2) Speed: 480 Mbps Module Alias: "usb:v4971pA002d0001dc00dsc00dp00ic08isc06ip50" Driver Info #0: Driver Status: libusual is active Driver Activation Cmd: "modprobe libusual" Drive status: no medium The lsusb information for this device is: Bus 007 Device 004: ID 4971:a002. When I run a blkid command, no UUID id displayed for this drive in the distributions that will not mount it. Any ideas anyone? |
How exactly is it not mounting? Is it just failing to mount, or is the drive not being detected at all, that is, no /dev entries are being created? Are you talking about the gui automounter only? Have you tried mounting it manually? What kind of errors do you get? Did you try fscking the drive? Is there anything different about this drive compared to the others that may affect what's going on? What does "fdisk -l show when you have the device plugged in?

Disconnect it. Connect it again. Wait a minute. Post "dmesg" output from the first line where it mentions new USB device.

Ok.. Try "dmesg | less", scroll up and post lines between the report on new USB device and the cyclical error you have posted.

And /dev/sdb1 doesn't appear? Did you try building a new vanilla kernel on an old distribution or installing new distribution kernels there?

I installed new distribution kernels; I don't think I am ready to try building kernels yet. I am using Mint 6 currently, but have tested Ubuntu 8.10, Fedora 10, and Mepis 8 beta 5. The drive behaves in the same way in all of them when trying to connect through the USB interface. I think all these distributions are built on kernel 2.6.27. As I noted in my original post, this drive still connects without problem via USB to openSuSE 11.0, which is built on kernel 2.6.25. Also, I don't know if you read in a reply I made to post from someone else, this drive will connect automatically in Mint 6 via its Firewire connection. |
Well, if you tried to compile a few kernels, you'd have a good chance to either make your distribution not spoil vanilla kernel here or submit a useful Linux kernel bug report.. But without compiling your own kernel it is useless. I have never seen such an error on my computers, so I cannot help you in feeding your curiosity.

Thank you for the attention you gave my problem, Raskin.
