I had a 4 HDD raid0 array which is working perfectly until yesterday. When it show the RAID Bios while booting most of the time it says 6 port 4 devices but it detects only 2. Devices on port 0 and port 3 can not be detected. And because it sees 4 devices but cant detect them while scanning that ports it waits for a while until a timeout. What might be the problem? Cant find a document or answer about this in internet. It is a too specific (for seeing 4 devices but detecting only 2) problem i think who really knows about raid bios for intel can easily say what is or are the resason(s) that can cause this. So i decided to post this here. TY
I do not know if this is of relevance for your issue, but I encounter too troubles with ICH10 and detection of a 2TB HDD ( http://communities.intel.com/thread/22558?tstart=0 ). Only today I learned in a chat with Intel support:
"... to keep you informed on Intel Desktop motherboard we have checked maximum of 1 TB of HDD capacity only and which was found to be working perfectly fine, ..."
The agent announced to escalate the issue.
