unique question about RAID 0

In a RAID 0 setup with 2 SATA drives, Does it matter if drive #1 accidentally got switched with drive #2?
I've had my computer disassembled for a few weeks while trying to replace the PSU, and I forgot which drive was SATA #1.
 
I thought It stripes the data, not mirrors it. Or do both drives contain a copy of the full complete file and then it stripes half the data from each copy when reading?
 
It shouldn't matter, it just needs the all the disks in the volume to be there (normal/healthy) In your case just needs the 2 to be connected. Perhaps some boards have quirks, but I've never experienced that.

Also, in your case, RAID0 is striped (one big drive)... not mirrored like RAID1
 
On boot the controller will discover the drives, as long as you have both of them it should work okay

I've migrated my raid 5 array across a few platforms, after the discovery process it identifies the array and is usable.
 
Man, now that I think about it, with multiple disks in a RAID volume, if it was picky like that it would such a pain in the ass!

Well then I got something else wrong with the computer because it will freeze during POST.
The short story is: this is my gaming computer, and it was sitting unused for months because I don't have time to play games. I pressed the power button to turn it on and nothing happened. I checked the power button and it was good. Replaced the CMOS battery because it was over 10 years old. Checked the PSU, it had a blown fuse. I replaced the fuse and it blew that fuse too. I replaced the PSU and now the computer is messed up. Took some pictures and posted them below.
This is the first screen that comes up.
When I hit F1 , it freezes at the next screen below.

Here is a picture of inside to show how everything is hooked up. I know the pictures won't help much but when I replaced the PSU I left all the DATA cables hooked up the MB. The original manufacturer who built the computer had all the wires stuffed between the case so they would be hidden. Which had them in a bind and made some too short to reach the peripheral. So I routed them in a practical manner so I can work with them. As a result I had to remove the HD's and redo all the wires in the front section of the case. I was having trouble finding a correct type of PSU. So time went by and things got moved around and I might have the HD's switched because I forgot to mark which one was #1.
Also just in case it matters this is a P4 Socket LGA775 with PCIE and SATA. Thanks for your help and I hope you will continue to help me figure this out. Please!
God Bless

Usually that failsafe mode message is from the cmos being cleared from a dead battery (or removed in this case).

The stuck at verifying DMI data seems like it's having trouble handing off to the bootloader
 
It sounds like it's not a simple fix that I can do. If only I could find someone that would be willing to be honest about fixing it right in exchange for good cash. (computers too old).
 
Disconnect both hdd's and see if the system continues to boot and give the message saying no operating system found or something similar. If it does, then you can assume there is an issue with one or both drives.
 
This happens to me when I do a BIOS upgrade and it resets. If the CMOS was reset due to loss of power, it's more than likely that in the BIOS you need to re-enable RAID. On my PC under SATA configuration, I need to change it from AHCI to RAID.

That was the problem, thanks. I had to change too many things on this computer before I got it up & running. And due to my inexperience to computer repair I did things I should not have done. You might say I got lost in the jungle. Anyway I finally found the HD configuration in an unsuspecting place. And now it boots to the desktop.
Thanks again for your patients helping a novice.
