Version 6.0.0 of the system software has been released. It is based on Windows XPE SP2 and solves many issues. Please provide your shipping address (no PO Boxes) if you wish to try version 6.0.0. We can ship you a copy.
Alternatively you can download a copy from the LaCie public FTP site.
FTP server address: 184.108.40.206
File name: ED v6.0.0 ECS.iso
Please note that the 4 HDD must be zero'ed for the v6 restore to work.
However, interestingly when we looked closer at the CD's included with the device they were V6.0 software. For some reason we received an unit with an old version of software.
So upgrade and things should be rosy.
