USB problems remain - but not for long I hope!

Asked by Roberta Jean

Or I presume it's a mounting problem.
On an HP 6700 Pavilion 4gigs memory running Ubuntu10.10 under menus: System/Administration/Disk Utility is the only thing seeing any of my three USB sticks when a PNY 8gig flash drive is plugged in. It's not on the desk top, it isn't seen anywhere else in all the other menus. The flash drive has, so far, been impossible to read any of it's contents. The drive works fine on our Mac and (excuse my wording) Windows machines. <[cough cough blehhhh] Did I just say that dub-ya word again?!?> It is seen when I open a terminal and do 'sudo fdisk -l' (lower case L). So actually it is seen but still unreachable. I have done a C: drive format twice now and it is still the same way.
I have come to one other conclusion. Ubuntu is way up ahead of that “W” thingy!

As per request:

That information is there in question 137852. I was asked to deliver it in a
different manner with more information, so I did. Yes, it has changed
because the situation has changed slightly and needs to reflect those
changes.

The information you asked for is here:

robertajean@robertajean-HP-Pavilion-dv6700-Notebook-PC:~$ mount
/dev/sda1 on / type ext3 (rw,errors=remount-ro,commit=0)
proc on /proc type proc (rw,noexec,nosuid,nodev)
none on /sys type sysfs (rw,noexec,nosuid,nodev)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
none on /dev type devtmpfs (rw,mode=0755)
none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
none on /dev/shm type tmpfs (rw,nosuid,nodev)
none on /var/run type tmpfs (rw,nosuid,mode=0755)
none on /var/lock type tmpfs (rw,noexec,nosuid,nodev)

robertajean@robertajean-HP-Pavilion-dv6700-Notebook-PC:~$

Thanks for asking!

Roberta

Have a look at: https://help.ubuntu.com/community/Mount
USB FAT32 keys are mounted automatically by daemon "udev".
But I don't know if udev manages NTFS keys.
Having NTFS key is unusual. Whay do you have such key ?
You can add these keys in /etc/fstab tab.
Also have a look at:
   https://help.ubuntu.com/community/Mount/USB#User%20Privileges

Thank you Delance.

When the flash USB drives are mounted on the computer they ask for security passwords. On the drives is some intellectual proprietary documents that I'm working on which is why they're NTFS as an anti-hacking measure. The documents also ask for passwords when I open them. Thanks to you I won't have to recreate them.

Your information has been very helpful and I thank you for being so knowledgeable with your work at Ubuntu!

Sincerely,
Roberta
