I had an issue with raid 5, when the system is booted. I believe it correctly detect LD and Port, so you can swap cable around while the computer is turned off and it will still be ok upon boot.
I decided to customize my sata cable with nice cable, my system was in sleep mode and I said to myself it will ok anyway it's plug and play!
But I mess up and switch port 3 with port 4. Upon resume windows never saw anything wrong. I decided to look at RaidExpert to see if anything was wrong and went for a synchronization with redundancy check only. It was way too long and believed that if anything was wrong it would have found out in the beginning of the scan.
Then problem start to arise, I reboot and windows want to repair my drive corrupting the filesystem while doing so. I shut it down knowing something was wrong. I look back at cable and realize that I've switch 3 and 4, with the system turn off I plug them back in correct order but upon boot they are assign like they were "reversed". So I boot back into windows (the raid isn't my main) and then put the system to sleep and switch the port 3 and 4.
Now everything seem fine, but I wanted to report this issue! I know it was my fault but isn't the system supposed to detect issue like that since it's plug and play.
