Comment 28 for bug 580952

Came here through Google. Very likely the cause of these error messages is a faulty SMB implementation in the proprietary OS of the Freecom Network drive. This is not a bug in Ubuntu.

In the original post, Willem mentions: "The network harddisk is a Freecom 500Gb, which is NTFS-formatted." These devices are built around a "RDC Landisk" chipset, usually the 2891 or 2882 which contain 186 or 486 compatible RISC CPUs.

Their firmware is based on the RTOS Micrium uC/OS-II, so it's not Linux. A bunch of RDC programmers wrote an SMB server on top of that and apparently only tested it against Windows XP and later OS X 10.5. Hence these devices are well known to cause trouble when using them with other operating systems. Unfortunately the complete source code is not available and made for a proprietary compiler (Paradigm 6, devtools.com).

Hope this information helps anyone trying to figure out the same error. The RDC chipsets were not only used in the Freecom Network Drive but also in Conceptronic CHD3NET, Fantec LD-H35NSU2, Packard Bell Netstore 3500, Sitecom MD-250, etc. I expect all these devices to cause these problems.
