Tomas,
The Fixes/Updates for driver version 5.04.2013.1016 don't seem too complicated:
Version 15.04.2013.1016 update
1. Package updated to include WHQL
Version 15.04.2013.1016
1. SWR 1.34 release package.
2. PnP ID's added for several platforms
3. Several minor issues resolved
Version 15.02.2013.0414
1. SWR 1.32 release package.
2. PnP ID's added for several platforms
3. Several minor issues resolved
We haven't heard of other outstanding customer difficulties. What hard disk drives do you have installed? Is your operating system installed on the disks that disappear with firmware version 5.04.2013.1016? The reason I ask is it would be beneficial to see if there are any log entries shown within the RAID Web Console 2 application. Without any information to troubleshoot this, its hard to determine the cause.
Regards,
John
