We're trying to install from scratch, a copy of Ubuntu Server 14.04 LTS on Dell PowerEdge T430 shipped with 4 HD of each 1To.
We have set up each HD with RAID 0 in order to enable Ubuntu Server to detect them.
When we launch the partitioning, we obtain a I/O error.Please, refer to the screenshot joined with this post.
A complete diagnosis has been done successfully without any errors.
Thank you in advance for your help.
