2009-10-21 07:19:47 NTFS Module: Permission denied

Hi,
I have enabled NTFS as module and also selected write support for NTFS.
When I mount a pen-drive in NTFS format, I am able to do the read operation but when I try to do write operations I get "permission denied"
Using 2009RC1.
Anyone please help.
Thanks in advance,
Jai

When the device enumerated, device property displayed “write protection off”. But still I am not able to do any write operation

so run `mount` and make sure the partition has actually been mounted read/write
also by default, things are only accessible by root

Mike,
I am facing the issue only after mounting with root permission. Please find below the log of drive enumeration, mounting steps and when I try to copy a file existing in root prompt to the mounted drive I am getting "permission denied"

please read the documentation:
The only supported operation is overwriting existing files, without
changing the file length. No file or directory creation, deletion or
renaming is possible. Note only non-resident files can be written to
so you may find that some very small files (<500 bytes or so) cannot
be written to.

Thanks Mike.
If you don't mind could you please provide the link for this document. I tried to browse for the document related to mounting a drive using NTFS filesystem, but my search didn't help.
