[SOLVED] One usb memory is working, another isn't

[Mark_in_Hollywood]

I have two usb memory sticks/devices.

One is 256 meg. It is working. Files can be moved from the hard drive to the memory stick and vice versa.

The other is 1 gig. It shows up as:

mark@Lexington-19:~$ lsusb
Bus 004 Device 003: ID 3538:0054 Power Quotient International Co., Ltd

but files cannot be read from nor files moved/copied to it.

From a LiveCD session, I have used GParted to partition and format the stick, time and time again.

This HH is less than 3 days old. All packages are up to date. No modifications to system files have been made. The device is listed in /media as a folder named: usb.

Please see attached screenshots.

Have you tried transferring files as root?

[Mark_in_Hollywood]

I don't know how to do that as root. I'm mostly a gui user.

If you give me the terminal command structure, for example:

sudo -

cp /home/filename

to where the usb drive is, I can try it, but I don't know whether to try to write the file into:

/dev
/media
/mnt

or all of the above.

I forgot this earlier

Disk /dev/sdb: 1010 MB, 1010826752 bytes

[rbc]

It should be
cp /filedirectory/nameoffile /media/disk

Try it as non-sudo first. If that doesn't work
sudo cp /filedirectory/nameoffile /media/disk

[Mark_in_Hollywood]

I'm a trifle baffled. Using sudo the files copied, but don't show in the Gnome file manager browse folder or open features.

mark@Lexington-19:/media/usb$ cd /home/mark/Desktop
mark@Lexington-19:~/Desktop$ cp /home/mark/Desktop/usbmounting /media/usb
cp: cannot create regular file `/media/usb/usbmounting': Permission denied
mark@Lexington-19:~/Desktop$ sudo cp /home/mark/Desktop/usbmounting /media/usb
mark@Lexington-19:~/Desktop$ cd /media/usb
mark@Lexington-19:/media/usb$ ls

In terminal, type this please and post back: mount

According to your third screenshot, the flash drive is being mounted at /media/disk, not media/usb. is that not true?

[Mark_in_Hollywood]

Output of mount:

mark@Lexington-19:/home$ mount

The screenshot shows as:

mount point: /media/disk

more than that I can't answer.

[rbc]

Good. So type this:
cp /home/mark/Desktop/usbmounting /media/disk

Then use terminal, or nautilus to navigate to /media/disk and see if the file transferred

[bumanie]

I don't know much about this, but I suspect the problem may be related to the 'nodev' entry. At least in fstab 'nodev' means something like - 'not to interpret the device'. I am no expert on this though, but it does seem that your usb stick is not being interpreted correctly. Sorry I don't know how to fix it other than your third screenshot does have a permissions button where you may be able to change something. You may have to wait for more expert advice.

[Mark_in_Hollywood]

Good. So type this:
cp /home/mark/Desktop/usbmounting /media/disk

Then use terminal, or nautilus to navigate to /media/disk and see if the file transferred

mark@Lexington-19:/home$ cp /home/mark/Desktop/usbmounting /media/disk
cp: cannot create regular file `/media/disk/usbmounting': Permission denied
mark@Lexington-19:/home$ sudo cp /home/mark/Desktop/usbmounting /media/disk
[sudo] password for mark:
mark@Lexington-19:/home$

see screenshot, Nautilus now shows the file in the device.

I see these lines below added into /etc/fstab. Will this solve this without affecting other usb jumpdrives? Is what is below currently good?

sysfs /sys sysfs defaults 0 0
usbfs /proc/bus/usb usbfs defaults 0 0
none /dev/shm tmpfs defaults 0 0
none /dev/pts devpts defaults 0 0

[bumanie]

You could try that. No guarantee that it will work. But if it doesn't you should be able to remove the entries you add. I have not heard of usb devices/lines to get usb to boot being added to fstab unless they have been hard drives with grub installed. Really can't answer what it may or may not do.

[Mark_in_Hollywood]

I rebooted using GParted LiveCD to delete any data or corruption on the jumprdrive.

I told GParted to delete the entirety of the drive and re-partitioned using Primary and ext2.

On reboot, the same problem, on the Properties page the device says: ext3, but on the media properties page it says: ext2. And still no permissions.

I tried:

mark@Lexington-19:~$ sudo chmod -R 755 /media/USB/
[sudo] password for mark:
chmod: cannot access `/media/USB/': No such file or directory

that's not it. Should it have been chown?

Is there a formatting command for this device like the old dos disksettes?

format a:/sys? or some such in Linux?

[Mark_in_Hollywood]

mark@Lexington-19:~$ ls -lh /media/
total 36K

drwx------ 4 mark root 16K 1969-12-31 16:00 UDISK 28X

drwxr-xr-x 2 mark root 4.0K 2008-05-20 10:44 usb

How do I change this line drwxr-xr-x to drwx?

[Mark_in_Hollywood]

So, I've made it worse?

mark@Lexington-19:~$ ls -lh /media/
total 36K

drwx------ 4 mark root 16K 1969-12-31 16:00 UDISK 28X

How can the line below be changed to look like the line above?

drwxrwxr-x 2 mark mark 4.0K 2008-05-20 17:16 usb

!!EUREKA!!

I have found a use for Microsoft operating systems.

I took my "defunct" usb memory stick/jumpdrive to a friend's house. Upon plugging the device into a usb port, Windows XP found the device, reported it as unformatted and asked me if I wanted to format it.

I said "YES".

Upon finishing the formatting, the device is now read/write.

Thanks to everyone who responded to this post.

USB Sticks should generally be formatted only as FAT32/FAT16. I think that is why you couldn't read off of it.
