When I try to copy or move files to my USB sticks, sometimes I can, sometimes, the system tells me I don't have permission.

These USB sticks were formatted in Windows. When I list the directories, the persmissions look the same, and of course, it says the owner/group is root for all files.

What could I look up to teach me what is going on here? Can I use Webmin to correct the problem? Could Virtualbox have done something to the USB sticks? I didn't have this problem when I first installed LM10. Sometimes one of my USB sticks automounts on /media/usb, other times it automounts on /media/ItsVolumeName. Doesn't seem to be any rhyme or reason that I can see up to this point.

Also, after the automount, there is no way to unmount w/o using the disk utility (from Red Hat) or umounting as root. Before, I could simply right click the icon or disk in the file manager, and select Unmount.

LM10 amd64 Gnome, Virtualbox 4.0.4 r70112. All updates applied.

Thanks.

Are you using more than one user account on the Linux Mint? The first user account that you create is different than the ones that follow regarding group membership.

No, it's the same account I created at the time of install.

I posted something relevant in "Isn't linux crazy" in the general forum.

1) you could make a usb drive writable to all if it is partitioned as FAT32 and formated as vfat with "mkfs -t vfat /dev/sdcx". It automounts with an icon in the Desktop. You could backup your files and reformat your usb drive and test.
2) There is umount; it could now be eject(as a disk), but not too sure. Once ejected, it need to be manually mounted again. Please check.

Best Regards.

I had the same problem and started formating mine

mkfs.vfat -F32 /dev/sdxx

Well, I can give that a try, but I'm going to research this some more with the Virtualbox thing. I don't recall there being a problem like this before installing VB. It may take me a while to figure that one out, but if I fail to find anything substantial, I'll backup the contents and try formatting as both snailchess and Larry Webb say. Thanks.

Let us know, I do not run VM, just an old fashion multiboot.

Well, I think I've found the answer. When I was fishing for USB info about my system, I went into Synaptics PkgMgr and typed 'usb' in the search box, and went down the line deciding whether to install any of the packages. One of which was 'usbmount'. This is the program that installed the usb0-9 directories. Anyway, I removed it, and now a USB device is available to LM10 unless I 'boot' a VM that shares that device. Then it's only available to the VM. Maybe that's not quite right, but right now, I can deal with it.

Can we close our own posts? Or does a SysAdmin have to do that? I think this one is done.

You can mark you thread as solved.
