Hi,

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.

Best regards,
