If the data is not important to you look to see if there is information on
sectors 1 to 63 on the hard drives.  This could be the reason.  Also, there
is information put on the back of the drives as well.  Lastly, Some Raid
controllers put the info in the Firmware. 

If the RAID info is in the firmware only way to do it is use the RAID
controller and set them up as JBOD.

Subject: [H] Hard Drive "remembers" it use to be a RAID0 member

I recently assembled a new system using hard drives from the previous
system. They are 2 WD Black 1TB drives I HAD set up as RAID0 boot array. I
re-installed them as individual drives under the IDE selection in the BIOS
(the motherboard is a P6T6 WS Revolution). They show up and work fine. I
deleted the partition, set up a new simple volume and did a simple format on
each. They show up and/or work fine in the BIOS, Computer, and Disk
Management.

I set up the new boot array (on different drives) and installed windows
vista 64 ultimate. I then switched the BIOS from IDE to AHCI. When I boot
the system, the 2 drives that appear as separate 1TB drives when designated
as IDE, become a single 2TB drive that "requires format," (i.e., the drive
appears blank and unusable) under AHCI. In Disk Management, it appears as a
single drive with a small partition, a large partition, another small
partition, and another large partition. When in IDE mode, no small
partitions are visible.

It appears that the two drives somehow "remember" they were a RAID0 pair and
nothing I do seems to completely remove the data creating this problem.
Anyone have any ideas how to split this pair up to be 2 separate drives when
configured as AHCI.

Second question--I thought that AHCI in the ICH10R would allow hot swap-safe
removal of a hard drive. I even installed the Intel Matrix Storage Manager
but have not been able to safely remove a hard drive (the option is NOT
available). The motherboard also has a pair of Marvel eSATA ports that also
do not seem to be hot swap/safe removal capable. I ended up installing a
JMicron pcie card that enables hot swap.

Any insight into these two issues?

Thanks,
