usb hard drive is not recognised
 

hi, i'm having problem with my 4 gb usb hard drive. i'm using knoppix and ubuntu live and none of these seem to recognise my usb. In ubuntu it doesn't show anything, the light on the stick just switch on ; on the knoppix a hard disk sda device appear on the Desktop and when i click on it i have an error message...

"could not mount device.
the reported error was:
mount: i could not determine the filesystem type.and none was specified".
here is the link to the result of the dmesg cause file too long:

thanks very much for helping.

After you plug in the device wait 10secs and run the command ' dmesg ' in a command terminal. Post last 15 lines of the output.

hi, these are the last 15 lines of the dmesg command after pluged in the usb hard drive :
end_request: I/O error, dev sda, sector 0
sd 3:0:0:0: SCSI error: return code = 0x10070000
end_request: I/O error, dev sda, sector 0
sd 3:0:0:0: SCSI error: return code = 0x10070000
end_request: I/O error, dev sda, sector 0
program dmraid is using a deprecated SCSI ioctl, please convert it to SG_IO

It doesn't seem to like the drive.It can be anything from the USB controller to the USB module with your current running kernel.

Thoughts are go into the bios and see if you have a box called Legacy USB and check it or uncheck it and reboot. See what dmesg responds after plugging the drive.

Try a newer kernel. Or an older kernel.

If a desktop install a PCI to USB adapter card and see if that works.

List current modules ' /sbin/lsmod ', ' /sbin/lcpci -v ', and also ' /sbin/lsusb '

I likewise am not familiar with the error messages, but have you tried to mount it manually? Assuming you know the file system that the USB drive was formatted under, specify that as well
