[opensuse] A bug in KDE when using ext3 in a USB disk?

Hello,community!
I'm just a tenderfoot,I don't know where to report a bug,and I even
know not whether it is a bug.
I describe it here,and I hope anyone can help me.And, excuse me for my
poor English,it's not my first language.

I'm using openSuse 10.3,and I often made it broken. So, I must put the
important date in my USB disk. When I need the data, I mount the disk on
my system. For security and avoiding the disk scrap,I format my disk as
ext3 instead of fat32.

But,in KDE,if you use the terminal to operate the disk(for
example,mv,rm,cp and so on), an I/O error will arise.The following
command it copy from my terminal:

||***The USB disk partition is mount under /media/SafeCopy automatically by KDE.***||

kermit@linux-myt:/media/SafeCopy/test> pwd
/media/SafeCopy/test
kermit@linux-myt:/media/SafeCopy/test> ls -l
total 4
-rw-r--r-- 1 kermit users 2 2005-09-10 16:25 Text File

||***"Text File" 's owner can't chmod it***||

kermit@linux-myt:/media/SafeCopy/test> chmod 777 Text\ File
chmod: changing permissions of `Text File': Read-only file system
kermit@linux-myt:/media/SafeCopy/test> rm Text\ File
rm: cannot remove `Text File': Read-only file system



||***For finding the answer to this question, I strace it.***||

||***THE COMMAND END***||

If I just operate the disk by KDE's GUI, there will not be these errors. But, this limited me when I must modify something as root.I must end the current session,and relogin as root.It waste more time,and not safe.

I hope somebody can help me whether it is a bug.
Thanks!
Kermit
