One thing to check, is that the BIOS settings have not changed.
Asus has an "overclocking recovery" feature, where if they think
the processor crashed during the last run, the BIOS can
start up with safe settings. That can cause any custom settings
you have used, to be reset to defaults. So first I'd have a look
through the BIOS, and make sure everything is the way you had it.
The way that RAID arrays typically work, is they keep "metadata"
on the drive itself. Another term for this is the "reserved
sector" on each drive. When you set up a RAID array, the RAID BIOS
writes membership info on each drive, so that if the drives are
connected to different ports on the RAID controller, the RAID
BIOS can still figure out which drives are paired together.
It could be that the reserved sector has become corrupted.
The following assumes you want to keep the data on the array...
Generally in a situation like this, I would like to have my
previously prepared backup ready to go. That takes the risk
out of any attempted cleanup operation.
It is possible to use a "delete array" and "create array"
sequence, to repair the reserved sector information. When
creating the array, you have to use the exact same parameters
as were used originally. Also, the relationship of the drives
would have to be maintained. For example, if you had a RAID0
stripe, and the array disappeared, you would not want to
swap the drives on the cables and do a "create array", because
the order of interleave might change.
Creating the array with a mirrored pair (RAID1), will mean the
array will rebuild. You have to decide in that case, which drive
has the good copy of the data, and then the good drive is copied
to the other drive. Copying the drives is how the RAID BIOS
firmware ensures the two disk copies are synced.
In the case of a striped pair (RAID0), you want to use the
"non-destructive" initialization option. A RAID0 can be started
without changing anything, and there may be an option to prepare
the array without disturbing anything on it. That would be the
option you would be seeking to use.
Now, since you say you are reinstalling Windows, it sounds like
there is nothing to lose by using a "Delete Array" and "Create
Array" sequence. You go into the BIOS first, and make sure the
RAID option for the storage controller is enabled. On your
second entry into the BIOS, then the "magic key sequence" to
enter the RAID BIOS screen, will allow you to create the
array again. After that, your Windows installer should be
seeing the RAID array as a destination for the install. Pressing
F6 at the appropriate time during the install, and installing
the RAID driver for the array, will enable Windows to see the
array. Without the F6 installed driver for the storage device,
Windows doesn't know it is there.
