I'm experiencing an issue with an Adaptec RAID 3805 controller. When booting the machine, if drives are connected to the card the boot process freezes after the controller starts but before it posts.
If I unplug the drives the boot process will get past this. I can access the array configuration utility, hot plug the drives, and configure and setup an array. If I leave them plugged in I get the same freeze issue as before. I have also tried with an additional sata
These drives were all part of a functional array previously. I have tried re-flashing the firmware, then a firmware downgrade/upgrade. Motherboard BIOS is up to date, has been reset to defaults.
I can't seem to figure out what the issue is, does anyone have any suggestions or experience?
