mount USB2: no valid block device

anon187 · 01-02-2006, 05:49 PM

Hi there!

I'm quite new to Linux and the distro Gentoo, and now I've ran into a problem that I just cannot solve myself.

What I want to do is to mount my Creative Nomad Muvo TX (USB 2.0).

This is what I do: mount -t vfat /dev/sda1 /mnt/usb
Then it throws back that /dev/sda1 isn't a "valid block device".

I don't know what more info to give except for the technical info that I can think of. If you'd like to help me with this problem, please ask if there's something else that you need to know! =)

Thanks for your help,
Nicholas, from Sweden

Hi,
Does the device node /dev/sda1 exist on your system? What do you get if you type "ls /dev/sd*"?

Also, does it work if you do "mount -t vfat /dev/sda /mnt/usb"? I don't have experience with this particular device, but some flash devices don't seem to bother with a partition table; the whole space is a single partition.

I have sda and sda1 through 15. I also have the same range for sdb, sdc and sdd. I'll also mention that I only have two USB-ports, and only the Creative-device plugged in.

That mount command throws back the same thing (no valid block device) for all sd* that I've tried.

In WinXP, it is automatically recognized as a "Mass storage device" and it mounts as a removable drive, and it's filesystem is FAT32.

Any more ideas as to what I can do?

Thanks again for all your help,
Nicholas

Hi again!

I solved the problem myself

. And for reference, my solution:

I recompiled my kernel (2.6.14-gentoo-r5) with some scsi-modules (I don't remember really which ones), and somehow the system loaded the right module automatically when I plugged in the device. The module's name that it loaded is: sd_mod.

Thanks again for the help, and hopefully this may help someone else! =)

Cheers,
Nicholas

After that I mounted with: mount /dev/sdc1 /mnt/usb

This is dmesg btw:
