I tried to copy some files on my ntfs disk (VISTA). I discovered that I can see all my ntfs disks, but there are no folders inside. This are my mount and df readings:

bogomir@linux-ivsy:~> mount
/dev/sdb6 on / type ext3 (rw,acl,user_xattr)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
debugfs on /sys/kernel/debug type debugfs (rw)
udev on /dev type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
/dev/sdb7 on /home type ext3 (rw,acl,user_xattr)
securityfs on /sys/kernel/security type securityfs (rw)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
bogomir@linux-ivsy:~> df

Help appreciated.

The drive is not mounted. You need to mount it read/write if you want to copy files onto it. You mount it with an entry in fstab if it's a permanently attached drive. But if it's a transient attachment, like a USB drive, you use the automount facility to mount it, and adjust that to be writable. Here is a walk through:
HowTo: Mount your NTFS Filesystem/Partition for Read/Write Access in openSUSE 10, 11

swerdna thanks. I was stupid Did not look into fstab, only in fstab-ntfs-config-save. So I had only to change the fstab entries. Thanks anyway.
