I have two problem with AMD raid.

1). How I rebuild array (e.g. raid 1) without booting the operating system (and starting raid expert)? In original Promise bios this function was implented, but the AMD bios has no that kind of function.

2). How I recover my data if the motherboard crashed? Looks like the AMD raid store the disk data in special format. Therefore possible recover only if the drive installed onto the same type of raid chip. If I connect it to standard SATA port, I see no valid data to copy or recover.

For 1, you'll need to read you MB manual.  I "think" you can recover from the BIOS.  (if the array is still valid, you just need to define it the same as it was)  If 1 drive is still OK, it SHOULD create the second automaticly.  (I've never used RAID 1)

On 2, this is true of 99.9999999% of RAID controllers.  Google it.  It's one of those reasons most "experts" say don't use ANY RAID.

For 1, of corse the manual tell nothing about recover. Before I use new config in sensitive applcation I try how to recover. I'm sure the AMD raid bios not contain rebuild function, and not recover automaticly. This function moved to opsys driver utility.

For 2, I use many raid. For example the "parent" promise raid build its mirror in a way to help recovery disk data using normal controller. How to do its very simple. The raid information wirted and end of the disk. In that way the nmormal controller and opsys read its data without any problem, and I can save it if ths controller failed.

Looks like just help yourself.

After more test the AMD raid work like Promise (raid1). Store the raid info at end of disk. If the motherboard crash, then you can connect its sata disk to standard sata controller (maybe external USB). You cannot start the opsys, but you have chance to save you're sensitive data from disk using standard copy.
