Cant mount R60 linux using USB. Help RAM GUY!


Recommended Posts

I can't mount my r60 in linux via USB. It's formatted ext4 with a couple partitions. The wierd thing is I can plug it in via SATA and mount it just fine. Also I can install lilo to the mbr and boot it via SATA or USB! In FAT format it is mountable in OSX over USB. But when I plug it via USB linux doesn't give it a sd[a-z] assignment but rather sg0, which is "not a block device" according to mount. Heres the dmesg:


[ 816.578030] ehci_hcd 0000:00:0f.5: port 4 reset error -110

[ 816.578053] hub 1-0:1.0: hub_port_status failed (err = -32)

and lsusb:

I am sorry Nick but I would suggest you contact the maker of the version of Linux you are using.


I am having the exact same problem. The disk can't be mounted with usb on linux. The problem is that Linux is not creating the /dev/sd* device needed.


I have tested with 3 different usb disks which are working fine, so it's not a general software problem. And I have tried to mount the disk on 3 different computers without success so its not a problem with the computer. (And the disk is working fine when using usb with Windows, except that it is called a fixed disk which it clearly is not).


A much better description of the problem including debug output can be seen at http://superuser.com/questions/225314/linux-usd-disk-just-create-sg-device

But it seems there is a bug in the firmware on the disk where it set scsi_level=0 which seems to cause problems.


Did you ever get it to work?


ps: I have tested the disk with Fedora 13, Fedora 14 and the newest Ubuntu. And they all have exactly the same problem.
