Hi,

I own a GA-X58-UD5 mb with 6 sata channels (ICH10R) and additional 4 channels with a different chip. system is running with 4x 2TB disks with BIOS set to RAID and W7 Ultimate x64 absolutly stable since at least 2 years. I now wanted to plug in a 4TB disk. But disk was listed with 1.6TB in disk managment (BIOS reported 3.6TB); switch from MBR to GPT did not change the situation. hence I downloaded a new IRST driver 11.0 something (old one was 9.0 something) as exe file from INTEL download page. installation went well (including management UI which i did not use). file copy (50GB) to/from new disk went well. 1 day later the system "suddenly" slows down dramatically. shutdown took 30 minutes. new start again 30 minutes. still slow. next start gave a blue screen with something "unmountable disk". virus test are negative.

might this be related to the new diver? if yes, any ideas how to find the right ones which can handle 4TB disks?

thx much in advance
Chris

Hi Fernando,

thank you very much for your swift reply. Very much appreciated!!

Just that I understand your feedback correctly: You are saying that it is RAID BIOS related (so the RAID ROM on the mainboard) if >2TB disks will be supported, correct? Given that the ROM version is correct, is there any specific IRST driver version needed to support disk > 2TB?

Best regards
Christian

It is BIOS Version 10.6.0.1091. so >2TB should work. Do i need to use one of your modified driver or any from 10.5. up.
Again thank you for your help!!
